In this paper, we derive a principal component regression (PCR) method for estimating the optical flow between frames of video sequences according to a pel-recursive manner. This is an easy alternative to dealing with mixtures of motion... more

The paper focuses on an approach to a near-duplicate videos search. The search is based on the comparison of scene relative lengths in the space L2. The comparison is made with Gale-Church hypothesis. The concept "shot descriptor" was... more

The paper focuses on the algorithms of the event detection in content-based video retrieval. Video has a complex structure and can express the same idea in different ways. This makes the task of searching for video more complicated. Video... more

Abstract: Several scene-change detection algorithms have been proposed in literature up to now. Most of them use fixed thresholds for the similarity metrics used to decide if there was a change or not. These thresholds are obtained by... more

В работе рассмотрен подход для поиска нечетких дубликатов видео. Поиск основан на сравнении относительных длин сцен в пространстве L2. Сравнение проводится с учетом гипотезы Гейла-Черча. Вводится понятие «дескриптора сцены». Для ускорения... more
