Video summarization by group scoring
In this paper a new model for user-centered video summarization is presented. Involvement of more than one expert in generating the final video summary should be regarded as the main use case for this algorithm. This approach consists of three major steps. First, the video frames are scored by a group of operators. Next, these assigned scores are averaged to produce a singular value for each frame and lastly, the highest scored video frames alongside the corresponding audio and textual contents are extracted to be inserted into the summary. The effectiveness of this approach has been evaluated by comparing the video summaries generated by this system against the results from a number of automatic summarization tools that use different modalities for abstraction
About loss of regularity and "blow up" of solutions for quasilinear parabolic systems.
Starting from sufficient conditions for regularity of weak solutions
to quasilinear parabolic systems, uecessary conditions for loss of regularity are
formulated. It is shown numerically that in some situations loss of regularity
("blow up") really happens accordingly to these conditions
