VideoComparison (version 0.15)

Video Comparison Tool

Description

It will take the vectors of motion for two videos (coming from a variant of shotdetect code allowing to store detailed motion vectors in JSON format, for instance) and it will look for comparing taking out the common chunk. Then, provided you have some image's hashes it will compare their signature in order to make up the decision about chunk similarity of two video files. ShotDetect is a free software which detects shots and scenes from a video (http://johmathe.name/shotdetect.html).
