Title:
METHOD AND DEVICE FOR CLASSIFYING VIDEO BLOCKS
Document Type and Number:
Japanese Patent JP3358692
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automatically classify images into sets of similar shots without finely dividing the image for the unit of a shot and without damaging time order property.
SOLUTION: First of all, the feature amounts of respective shots are calculated and the shot is used as the block in an initial state (step 111). The degree of similarity between adjacent blocks is calculated (step 112), the adjacent block or step showing the maximum degree of similarity among the calculated degrees of similarity is merged with one block (step 113) and the feature amount of the merged block is calculated (step 114). The steps 112-114 are repeated until the classification is sufficiently performed, and the number of blocks is gradually decreased.
