Abstract

A new motion feature for video indexing is proposed in this paper. The motion content of the video at pixel level, is represented as a Pixel Change Ratio Map (PCRM). The PCRM enables us to capture the intensity of motion in a video sequence. It also indicates the spatial location and size of the moving object. The proposed motion feature is the motion histogram which is a non-uniformly quantized histogram of the PCRM. We demonstrate the usefulness of the motion histogram with three applications, viz., video retrieval, video clustering and video classification.
