METHOD FOR COMPARING GROUPS OF IMAGES

摘要

The invention relates to a method for comparing a group of images, called candidate group, with reference groups of images, said reference groups being stored in a database with their representing key frames to which are associated local features and global features. The method comprises the following steps: - detecting an image within said candidate group, called key frame; - computing a global feature of said key frame; - comparing said computed global feature with the global feature of each key frame of the reference group; - if the differences between said computed global feature and each stored global feature are above a predefined threshold then: computing a local feature of said key frame; comparing said computed local feature with the local feature of each key frame of the reference group.
