SIGNIFICANT SCENE DETECTION AND FRAME FILTERING FOR A VISUAL INDEXING SYSTEM |
摘要 |
<p>A video indexing system analyzes contents of source video and develops a visual table of contents using selected images. A system for detecting significant scenes detects video cuts from one scene to another, and static scenes based on DCT coefficients and macroblocks. A keyframe filtering process filters out less desired frames including, for example, unicolor frames, or those frames having a same object as a primary focus or one primary focuses. Commercials may also be detected and frames of commercials eliminated.</p> |
