Title:
METHOD, DEVICE, AND PROGRAM FOR SEARCHING FOR DYNAMIC IMAGES
Document Type and Number:
Japanese Patent JP2017021606
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To conduct searching or grouping using a dynamic image itself as a query more precisely and more easily with lower cost compared to a conventional case.SOLUTION: A feature quantity extraction part 22 extracts the respective feature quantities of a query dynamic image and a target dynamic image. A dynamic image representative frame selection part 23 acquires representative frames in chronological order of the query dynamic image and the target dynamic image on the basis of the relation of the feature quantities, using one of a time-interval k average method, a time-division k average method, a time-binding pair-wise nearest neighbor method, and a time-division pair-wise nearest neighbor method. Further, a similarity calculation part 24 obtains the similarity between the query dynamic image and the target dynamic image from the similarity between the representative frames of the query dynamic image and the target dynamic image and searches for a dynamic image which is similar to the query dynamic image on the basis of the obtained similarity.SELECTED DRAWING: Figure 1
