OK this last talk of the day it's gonna be by Radislav on which kind of our about scale-dependent du more on metric analysis of pleasure mapping naggin and pound that and we want to of and but but a given the genealogical dependency you morphometric analogy and the manga part about located at the southern bank then it to the research probably a year ago when being at University of Nebraska demand are working on my much I the degree it would have to be mentioned is
that that approach approach to 2 different techniques together 1 of them is that along way to the problem of ultimately geomorphological mapping in in the sense of complex feature extraction of older D E and the 2nd 1 is the region related and it deals with the geological and geomorphological problems will located at 9 about but the region which is 1 of the youngest other the place of the all Montagnier area of a specific as well as the principles the used and that basically the dynamics of the prostitutes which 0 Purim holiday it's because of the very high the vertical exaggeration and that the amount of a potential energy divided by the elevation and the the changes it has to be mentioned that the climate causing all the factors which influence the location of the glacier at denying by but had really again at the data can be found that by a very small angles located around the region and sometimes you need to
medical age very precisely in the sense of a glacier inventory in the sense of the global warming order what the capacity and the and the human community which leaves in the interval and end up in the lower part of the valley when you're using remote sensing techniques you may get into the difficulty which in the which lead into into the fact that glaciers there's a lot more recovered so the very can I don't like the solar energy in the same way and you cannot distinguish the places where from very walls and it's important to note that sometimes the same level at the can be a can be being generated by 2 or more problems so you have 2 or more properties while the result is only the same model magically to I want to arrive at the very end a relationship between the monochromatic properties of the terrain and the real landscape land for the real to political and the 2nd objective was to identify the so-called imaging is there an object in the Central European literature known as smart and to find out whether there is any relationship with the in the that is because attributes of the monitor I assume that there is a relationship between them automatic properties and land on and basically we cannot leave it there also and assume that moreover can be extracted from the DEM music that analogy a and it really be at the next big we had to the program yeah he has to be taken into consideration when dealing we can imagine non trivial this the German logical framework in the matter energy in action and the land from the queue here here during the all have a feeling that something like that at the however no presided mathematical definition has been given in the hands of of yeah can how many here the level of out there but the 2 programs we can have a small when applied to a couple of landslide light or slope land can build all valid when you put a value and the region together you can get them manner a vindication scale to a continental you can get the example the bad examples in the land of the urinary network between and mountain region those 2 networks that kind of a equivalence and during aerial object we can have for example and Beijing in their mother died in an area oracle Asia reality the study area 9 properties located at node and make them over here and basically that the 9 departments at the edge of the river an industry with all those mountain region they originate at the top of denying the part about and they divide the
inflation rate could value largest of glacial valley at the area I was talking about the generative theory for example the 1st order topography is built by the method of it because originated by the tectonic what it posted here attractor located in located over here the 2nd order to programming is that the problem being generated by later glacial valley while the region get connected together the correct order to bother the smaller in size what do you you want to buy the land of light and the principle is heavily dominated by the value of the river in 1 of the highest at the place of the uh those of the same but cold and if the on those was very low this is the 2nd picture of the research area through that 22 there were glacial valley located at the 9 the private area particularly part of them were taken for the more in-depth research recovered later and Dutch English given rectangle rather than the area with a typical Alpine glacier so it doesn't doesn't go to at the end of the valley those going to the water at Beijing extracted using air water in the the input word that what that procedure was a digital elevation models made of and support their images that images you may don't think about it you make you know you may have a question or was it really have to to develop automated factory paving in that had really exaggerated area but if you have a feeling that the more exaggerated that there is the more easily it into it to extract the typical melody but 0 multivariate had to be you girls glacial really extracted from the property and basically in the combination over the region and the a man was used by now you probably know that each what it was expected that apparently playing with a goal region and a mouse then a dot blot it was used to compute difference that think about the individual glacial melting then S page was used to build the find a problem that of image this didn't try hard was a world in which enable all all rules I was able to relieve the state art out very however probably newer pendulum and then 24 CPU is generating computer but the
main advantage was of almost unlimited light the area the graphical capabilities and almost a limited of the while it in the correct from the bathing at larger here at the level of it might be quite difficult to go more in depth and to try to extract the smaller the that that would be a really non-trivial OK that's not the result of the Prodigy and energy by 20 meters slope and approach curvature as you can see there's a lot of noise at the provincial on the latent and basically hi my current paper variations and I want to I wanted to use the clicker analogy to it's about money out it necessarily to do and data preprocessing you cannot work which had to get slope angle map
that make it here is the methodological design the part GM will propose an model magic analogy will depend on the begin to graph then the marble top were extracted using clustering and then clamping then those model what is the world of and make the problem curvature and then dental character the you as he had then the new edition of field were taken as the if the data for the following for each model itself from the elevator and there was computed mean elevation and maximum elevation minimal elevation that variation and loss and the head of the grayscale images what you the reader might be the same person rope angle but that each individual market then by destructive effects of these map and some of them were chosen In the event that they represented the the body of a glacier to be back the best there was effect together in 1 month you will be mobility data and then by the final clustering what then the final clustering was performed and in ideal situation the matter could be divided into 2 region later and that not later in the English goes we talked about applications
using in the research grant was mainly used in that stage of the procedure are there right now I can imagine do you only open source for the entire procedure if you think the island region and in this particular packages it is they got promising result property regularized by everything India this quite a because knowledge of the visual on the latent and basic and mainly I deeper variations over the small area so what I a randomly sampled the origin DM taken 25 per cent of the original because and use them beat are in the algorithm using that make benzene and moving the produced the and don't be confused by different rate of those images which is the result for the rope angle that the best visible application could change the slope of the area while understood data preprocessing that I recommend data variational was removed the result was close and think again I candidate variation was removed by moving release build the 3 D media but you have a histogram over here that the body of the great but integration you grayscale images because if you use colourado sometimes you may be computed with the result will degrade the images which approach is that when 280 take very very close nearly all of the data can be the result of property and and completely remove he did his mother and baby and there's a lot of anger the molecule I used for a very occasional the proper analogy basically the the probable error rate on the beach you know that the problem of water flow playing the elevation of arrival from the original DM but that but they about evenly distributed over the over the and entire the year so it toward of the importance this the lower lying in the original BM the baseline is different than both the basically the extremes of the world were removed but the end of the slope was preserve and that's what I want I propose that might be because of the final analogy orders from 3 D images of the slope and bank and of the so bandwagon and the slope angle it a configurable the level of Angola is that the way that the greater body and it's even better to be added to the 3 D image of the map of the of the ecclesia that that's invasion encourages you playing quite a bit of it the parameters is important because of the generated better curvature and but this is very hot very large geographic regions so it could be there the results that the very large geographic area that has been more than the 9 kilometers of the direction the results of applying the analogies don't at 8 o'clock class that made of books and things like a decline because of i will not be now and well was much again educated having a couple of results available in front of you don't that model of made of angle very figure will get very typical spatial pattern of the individual of individual moment of located at about a great of ideological died while the moment of of the World Bank located at a very low they differ in I very much very very interesting don't of them patrol more appropriate parameter and all that and in curvature and you can see more details at the body glacial and located at Bendigo along the segment of the glacial while the market at the value very delicate Celtic that both are very dendritic structures and it's hard to explain I don't know what symmetricproperty computed for each of the model taken elevation and slope angle man what part of the you that the the the elevation envelope Bengal were used as the input data yeah the great calmat representing those that would be so then i'll monitor properties represented by gray scale image this for example means angle of computing for each you
should read the map in the following the minimum value I the maximum value of life which means that the law values of the mean slope angle of the 2 molecules are located at the place of the body Galatians the same monitor or monitor properties based on a small angle model if you can be a multimedia didn't make any sense at at workplace extraction but some of them if you don't have highly usable I was looking for but imagery so I can put them together in 1 mole per layer data around and use the final class that analogies so mu 1 or 0 and later on the language so that there are more automatic both monitor properties based on what curriculum at a level that really didn't make any sense but 1 of them very good developed based on the meanings of angle but highly usable I to have them mean slope angle based on the graph of the original model and mean slope angle used from multiple of Europe anger monitor I use both of them I take them together in a lot more people play around applying analyticity to class so many later on obligation yeah there is to apply the classical analogy that cover blade light from nonglacial plenty of but this is really because of the analogy glacier something between later and a very low value slope the next picture but then the result of 5 and a class like that analogy the the main is and the girl with a higher number of glass there is were not improve didn't improve both of the result and you can only be determined by building a declared In independently would agree that we can occur it was locally made the value we can make the more which is not glaciated no but it extracted data the parent features which are not glaciated now but that's life in general the glacial feminine and this is the angle for the greater than that is that's what should be dead in the only we always want to use of there's no generating and monitor production the only in other in other words we want to have a a land forms to be homogeneous in a random automatic properties but what if there is a land and water vapor homogeneous change of the rope on homogeneous change of the curvature were homogeneous gender I think it's also the heat and the type of the generating we have to think about the then that he came out when looking at the that dependent man that is run geometry get review called paper which should be taken into the consideration of when we want to marriage but then more with in the real the that and and that shape the position of the century or the longer segment of the market model or the number of the neighbor model of along the that along the along the centerline or contextual relationships should be should be studied and developed the 1 of the moment can be merged together and for example I know real highly yeah article on highly heterogeneous land when we take a look OK a couple of times last slide that it take a look at the distribution of global and conventional curvature integrate scale the Candida but the feature reached the alienated later almost perfectly however contrary to that have a clue how to use that local change of related to extract the glacial or any other conclusion yeah the automatic analysis provided some new in life however it's not it is not a trivial task to my above heterogeneous plentiful and save and contextual information should be taken into the consideration of I would like to thank the couple of people and situations were put in the project and then a supporting my participation of that culture and I think you really think
few
whichever discrete a couple questions and using the research they you you were presented here and do you have any method to need the volume of the glacier and the the density of of rock return I if you know the matter which can they come into computable inoculation that a whole founding and basically the volume of the juridical like the volume of the real world ladies 1st the almost precisely to make the number of available or they can be available the couple e-mails it was found in the approach to make the profiles and then compute the volume by all watching all those Williams segments together that require fieldworker connecting that required was a couple of brought by using it was receiver and the Lin another question had would uses a radar on updated to penetrate the who so by methodologies not then at the end of the that but I think I think it was something like that that 1 time and the final question was you In and really here and it the risk of the quality of the result of the that we can say that the the an eroding very very drastically so is there a risk of influence laughter they likely the and that part that region is known within each period of time and then that the perfect lighting appearing and the mechanism is like that the
glacial moraine doesn't allow the water to leave from the water and the water is accumulating in between the glacier which is the source of the water and between the front rain but when the amount of matter at the the critical value that then you know not to be stable anymore and that among the working with the very high of speed together derive market and everything is coming through the valley capital that and even of the documentary and then the real measurement we would down to make the amount of water in the of their goal of Iraq's OK obtained without 3 questions in 1 perfectly content tangled speakers in Ontario requested offline analysis you all tomorrow morning what not an age of their knowledge that they're very glad that we have that he there should have been an eye in our yard they get the food they buy that for some problems but it has allowed only to be told you can um the keep that they had a great day after out right now where you know all you were if you want to rule the remainder of their and their informal and uh the 1st meeting OK and outdated you want there that with the x
