METHOD OF OBTAINING A MEGA-FRAME IMAGE FINGERPRINTS FOR IMAGE FINGERPRINT BASED CONTENT IDENTIFICATION, METHOD OF IDENTIFYING A VIDEO SEQUENCE, AND CORRESPONDING DEVICE

摘要

A temporal section that is defined by boundary images is selected in a video sequence. A maximum of k stable image frames are selected in the temporal section of image frames having a lowest temporal activity. Image fingerprints are computed from the selected stable image frames. A mega-frame image fingerprint data structure is constructed from the computed fingerprints.
