and next up this 3rd yeah I was about to say something about about here and you you got into this slow-acting efficient here time from murder Australia but there may be other than now so you can talk about that improving the GM generation by enhancing the resolution of remotely sensed digital imagery but think you 1 of the
things that we the only OK out them and the 1st the 1st
place and down on I like to do things to the organizing committee for given the opportunity of being presented but a quick presentation and along which Marcela model and quick and yes my name is that out gave most common among university students on world university student and the University of Newcastle Australia and located about 180 k no told the Sydney with a population of about 400 thousand and people at Professor justifies my current supervisors In the area of databases where the relational structure model which combines a series of crimes of the same object and that I create a higher resolution and composition and you can help in the for the full legal on the left and the right and an pure solution where the combination of all of those images which have to be and and place of the of upbeat the bias of people mounted and the generator of a high-resolution image In this case you can the caller comes from Australia and is worth 1 dollar the the the presentation outline and digital image resolution enhancement like the and well I believe white implemented at writing out the resolution that had to you acquire resolution I do we acquire the images the image matching registration process and some genetic consideration we go along with that some medical examples and an application of a very simple Boolean model and finally all asymptotically all and and future future work as well and please think of structure from images in order to optimize have a treaty models of an object thing for them at a remote sensing and it is probably the best way to have different images taken at different angles the same object and by doing that you can obtain a Treaty of the object that have enhanced-resolution well it in a way that your views about the laws solution image is less visible than the 1 on the right we show the high resolution and then on the bed of digital elevation models will be obtained from the higher resolution images of the image from the left this too much from the right and that Indian indeed thank the structure of the algorithm basic cost that much more complex than that a of summarizes just to confirm the idea and you better get quite scary images which is not enough to acquire images of object from different angles and you match the images and the matching the images left and right we 1st and match and the register the images on the left then imagine and registered images from the right and finally we apply an enhancement processes and which give better images and thereafter we created the model accreditation of images and yet we can acquire digital images from scanners and digital still camera digital video cameras and satellite system the satellite system may be a problem because when you have to pick up of the images from satellites and the satellite will more gotten down and I think that by and composition of Cloud and shade where was kind of digital video cameras and digital cameras so we can kind of control the situation imagine session in between we have to images and taking at the same object taken with a flight movements of pixel movement at each digital image can be presented as well because we have evolved we temple a lady because in the corner which is X X 1 Y 1 but the
elevation with the great value and to create a couple of services and we try to match those services in the where those surfaces that correspond to 1 another and how hard it there simple representation of that 2 2 images of the target image and we have the observation and it has to be because the level currently images station in matching of surfaces and have an accuracy of about 0 . 1 of the peak and going forward and you can find
images at different positions and therefore and thereby and you can improve resolution that the interpolation biologically image that actually places in the pixels sense but it cannot yeah simple
register the people and the importance of example of how the produce the is they a that because nobody can took a picture and is lowest pixel we map it we map it on and a lower not higher resolution and great and we create an equation which we write and our little dog detected with friends and it will the and to the right of the little higher resolution because it is the birth of a weighted mean of the area covered by the you have a low-resolution
picture of onto the violation because and extremely but this can and people example here the 1 I'm not aware that you can build it with parent paper and I did that because we want to find and lower solution and the the the the pixel detected by the camera they trying to construct a simple equation and as you can tell that the 1 which is the variance at pixel i call it a variable X 1 but half to the next big big filled with color and they're probably will plus take the next 1 will be explored but I have a lot of data on the here we have another image which starts with apple here again we can form and use of equations that in time in the same way that led to use of 14 model because when a molecule represents a thinking of and this fight because they can be represented by the ballistic equation the and then by evaluating the various at that point 1 and half a point x is and we create the a little weight polynomial and and encompass of all the operations and multiplications where we want because of the final equation having a spherical but linear equation like this we can simply told them by the squared and then get the of a good estimate of the actual pixels the characteristics that obviously have people right from referral and global search for the presentation of the 2 and I generate a function which incorporated the edges of the image as well because of the surface and does not require the use of sparse sparse matrix storage techniques and support for a more balanced system of observation equation as compared presented to polynomials that can some of in between points can just go up and down I'm speaking too bluntly now but 1 example of this situation I can that this is the
simplest and enables them from Australia what I did was just to put scanner Canada different positions and that get different that pictures there will define but as you expanded as you expand the natural increase in spending image you can double that would go there will be a little bit but by combining all of and then you can come up with this product and in this case you can probably see more
clearly and how it with a picture of a picture and it can also apply rotation the degree of the provider for that the ratio means the 1 . 0 means that I have a picture which is which is great 1 . 7 that because of the course images video that is 100 by 100 it will be 100 headed by 170 that's 1 at the pitcher plant so it is just a postcard that i can solve for this can you can buy the book and against the application parliament inspiration to 1 . 9 important and I got an enhanced confidence that were kind of it should be much better I guess 3 D reconstruction from that is the last of the cost and said I think not apply the sort we the situation and this is again a very simplistic example and the yeah global justice arithmetical object and I took the only images from the left and from the right of this section I scanned them and created course images and from then tried to reconstruct back to the trans surface there is much more important to do it but I'll try to you
can find information in the paper in the future directions and this is this concludes my presentation and wanted to the capability of the Boolean model as a tool for creating applications using other models with the presentation of digital image like the spline wavelet a comparative approach independent affecting the other methods for aerial and satellite images directory to interest me more than 1 but there are applications that you might not be interested like industrial video images architecture and also security issues the clicker thank you be
OK so now I need long question what I had in mind is what the church of yes there is another
important thing the crucial and bring to the image registration and that the services matching is got by that doesn't work it has to to be a sub-pixel movement between the images
so you know exactly when you match the surfaces represented by the digital images is presented by surfaces you must have a like the best possible matching for that we have achieved accuracies for positive examples have successfully by for and that sort of thing you can have a picture of what can we do not use control points is just a normalized cross-correlation of great value on which also determines the rotation as well and that got that images of course you must get better digital elevation models there is no doubt about that if you have images from most the OK
if it's clear that he made co-registration his edict the key here there would be OK back that this correlation the deal corpora for making it that world although they be made on selected pointer without the knowledge of the whole image he had them the letter candidates for example they use normalized cross-correlation and using Windows
assailed the just look for the best window and so can do when correlated and therefore it better right the achievements of the lectures that have been in category we look at the heart of the and if the computer has been entirely and I want you to legislate about a year and a think about that construct a pendulum a professor and and then there's the and so in terms of time and if I if I was to process said about training images those 6 6 recorded by correlating would take about an an hour and a half of the lecture example in the case of the control sorry about my
accent we I think in your education and good if you want to overcome that can go and then you have a different kind of knowledge that in an independent American down where replicate and the problem is that the whole world with a whole robot if you agree with me a the event and that is different in that of that there is little difference that in the in that is what of
it is 1 of the things that blindfolded in explains that this little completely yes in this case you need the number 1 limitations and you need to have the object here maybe that's a little bit of a company on the so and what happens if you have of different a lot conditions and you took a picture I took a picture of you know the sort of a video camera 2011 trying to 2nd and then I do to venting tomorrow you invent position but tomorrow we got a cloudy and then that a
problem here a quick question and you have a resource
online or where the presentation can be we can here or the this time from the data this paper it on if you wanna about a while yet they they in the paper that not the the main paper example you can it by and the other 1 is not thank you thank you thank you very difficult to understand I just want 1 people with the source code that comes with it you have a choice good for the career planning on releasing it but it not obvious that it out and compare them completely the finally the king of the program which not that class what 1st then what want 1 as an advantage for use by the
procedure on the area of of the room we during the distortions which distortions caused by pairing there because if you had yet it 1 of my own investigation that's why I put it at the end and trying to apply these were an immune satellite images and if I had the chance to have a say on the set of all the images in that simultaneously taken as being distortion will be available on but an aerial images is not so yeah yeah so if the difference in terms of time so that you know that there possibilities here alright great thanks again
this is what happens when you know what you get all of that they think again to the
organising committee at a time and the
