Scene-Based Shot Change Detection and Comparative Evaluation
A key step for managing a large video database is to partition the video sequences into shots. Past approaches to this problem tend to confuse gradual shot changes with changes caused by smooth camera motions. This is in part due to the fact that camera motion has not been dealt with in a more fundamental way. We propose an approach that is based on a physical constraint used in optical flow an...
متن کاملCompressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملScene Structure and Change Detection Running Head: Scene Structure and Change Detection Scene-like Structure Enhances Change Detection
Does scene-like structure enhance change detection? Theories of scene perception, neural representation of scenes and object recognition seem to imply that it should. However, extant evidence from the change detection literature is thus far ambiguous with respect to this question. The four experiments reported here demonstrate that scene-like structure does, in fact, enhance change detection. I...
متن کاملRobust video shot change detection
In th i s paper we present a novel improvement to existing schemes for a b r u p t shot change detection. Existing schemes declare a shot change whenever t h e f rame to f rame histogram difference (FFD) value is above a particular threshold. In such a n approach, a high value for t h e threshold results in a small number of false a larms a n d a large number of missed detections while a low va...
متن کاملScene Change Detection Based on Audio-Visual Analysis and Interaction
A scene change detection method is presented in this paper, which analyzes both auditory and visual information sources and accounts for their inter-relations and coincidence to semantically identify video scenes. Audio analysis focuses on the segmentation of the audio source into three types of semantic primitives, i.e. silence, speech and music. Further processing on speech segments aims at l...
