Video evidence appraisal using changing keypoints: A case study

Abstract

The objective of this paper is to present the video authentication method that is accepted as evidence in court. In this regard, this paper aims to compare and analyze the changes in the keypoints at the door and peripheral parts of washing machine in the video required for authentication. To this end, two keypoints were set in this video. The first keypoint was set at the door hook of washing machine in this video. That is to say, the first keypoint is a “moving keypoint” because it is set at a moving object. The second keypoint was set at the latch hole of washing machine in this video. Unlike the first keypoint, this second keypoint is a “fixed keypoint”. This comparative analysis on the above-mentioned two keypoints provided the objective authentication result, thereby playing a big role in proving the innocence of defendant. © Research India Publications.
