Key-Frame Extraction Method from Single-Lens Undersea Video Sequences

Abstract

The process of key-frame extraction of the undersea video is different from that on the land. The effective key-frame extraction will promote research and retrieval of underwater video. In this paper, we first introduced the characteristics of the undersea video, and then proposed a new key-frame extraction method based on Sensitive Curve brightness change for single-lens undersea video sequences which measures the light shot boundary brightness change. The experiment results show that the proposed algorithm can extract key information of the undersea video quickly, and have a good performance for the noise point.
