Automatisierte Medienanalyse
Diese automatischen Videoanalysen setzt das TIBAVPortal ein:
Szenenerkennung — Shot Boundary Detection segmentiert das Video anhand von Bildmerkmalen. Ein daraus erzeugtes visuelles Inhaltsverzeichnis gibt einen schnellen Überblick über den Inhalt des Videos und bietet einen zielgenauen Zugriff.
Texterkennung – Intelligent Character Recognition erfasst, indexiert und macht geschriebene Sprache (zum Beispiel Text auf Folien) durchsuchbar.
Spracherkennung – Speech to Text notiert die gesprochene Sprache im Video in Form eines Transkripts, das durchsuchbar ist.
Bilderkennung – Visual Concept Detection indexiert das Bewegtbild mit fachspezifischen und fächerübergreifenden visuellen Konzepten (zum Beispiel Landschaft, Fassadendetail, technische Zeichnung, Computeranimation oder Vorlesung).
Verschlagwortung – Named Entity Recognition beschreibt die einzelnen Videosegmente mit semantisch verknüpften Sachbegriffen. Synonyme oder Unterbegriffe von eingegebenen Suchbegriffen können dadurch automatisch mitgesucht werden, was die Treffermenge erweitert.

you know that turns but thing that Battle of the Bands the other thing going on so thank you 4 thank you for all the organizers so fast John Bosco saline 18 shops and thank you for being here for 2 listen to me I'm going to talk about a strong word this minus a provider of statements at contained in France the topic is about the regularity properties of some run members sit around and talk about it at another conference for young people some glad to read talk it through to all these 2 2 2 2 2 some the young people that up the know yet so it's a good occasion the this impossible of a class of market processes is dropped the basic problem is is is the falling so let us consider of continuous time run the stochastic processes are indeed so X In 0 1 the letter defined the obligation Meyer of this process which is separately the time spent by this process at any fixed Maribel setting already so the question is the regularity of all this matter this run In the 1st the director the ruling the most basic question is is the absolute continuation of this matter so in In and moderate terminology is also called occupation downstage In the mock organs college context it is often called look at times so when you look time nominee we can consider another kind regularity properties for this matters it is called local dimensions so for this matter we consider a point in the in the in the support of we search for we want to observe some kind ,comma old fool them occupation narrow center at this point acts it is simpler than the positive room number age such as they have this relation of it is the 1st of what is not always what we find cause this limit economic may not exist and under another observation is that follow some simple for many in that happened that this explanation age may depend on the position of this act so

find by this process is is this :colon it Is recognizes the casting is because in respect to some Paulson plant process focus and Paulson naira generated by possum .period process was this often this intensity I did so let us remember that we want to study the the the hostile dimension of this side of singularities so need a translation from this formulation and the way true to computer to do the competition look so the 1st saying that rely on them and then we can say is that we consider it .period acts in support of this matter this follows Marra is just the rent of this process with some closed with his they consider appointing the in the in the support we can series quantity will consider planted in the the set with this project so the solution is needed at age minus edition shown sold for even minor scales can you 0 we have this inequality it is the best describes this the time spent by this process and inside the ball with his radio spot on it is it is offered wanted by something like this and news that the process cannot be too slow so this would translate into the incremental process and it is a means that it was an increment Of the process is larger than the increment power to some 1 over age essentially not employed by Baker OK so when a son increments which means something from his estimates to do and for other connotations for the 2nd

case estimated is is the following if we consider increment this is not exactly the increment of our process and but that increment truncated large nigger nigger and 2 near under then the the the the planning firm and power to 1 lower Delta Is a truncated or large amounts officer of a certain scale then we have this uniform control for the uniform control for increment of the process and a lotta Johnson's on a much smaller to control once we have this we can kill good estimate for this

Abstract  A point in the state space of a stochastic process is called “thin” if the associated occupation measure of the ball centered at this point is exceptionally small. We consider in this talk the Hausdorff dimension of thin points of a class of Markov processes with jumps. This is a joint work with Stéphane Seuret.
