Abstract
A system and method for analyzing video include segmenting video stored in computer readable storage media into keyframes. Near-duplicate keyframes are represented as a sequence of indices. The near-duplicate keyframes are rendered in a graphical representation to determine relationships between video content.
Claims20
A method, comprising:
- segmenting video stored in computer readable storage media into keyframes;
- representing near-duplicate keyframes as a sequence of indices;
- and
- rendering the near-duplicate keyframes in a graphical representation to determine relationships between video content, wherein the graphical representation includes a relevance to a topic and a relationship over time between similar videos within a corpus of videos.

A method, comprising:
- segmenting video stored in computer readable storage media into keyframes;
- representing near-duplicate keyframes by descriptors;
- creating equivalence classes for the near-duplicate keyframes;
- representing videos as sequences of equivalence class indices;
- sorting and linking videos in at least one equivalence class;
- and
- rendering the near-duplicate keyframes in a graphical representation to determine relationships between video content, wherein the graphical representation includes a relevance to a topic and a relationship over time between similar videos within a corpus of videos.
