Target Segmentation and Feature Extraction for Undersea Image Based on Function Transformation

Abstract

Because of the specialty of undersea channel and the complexity of undersea environment, many uncertain factors affect the quality of undersea image. Consequently, it is a difficult problem to segment and identify targets for undersea image. In this paper, a novel target segmentation and feature extraction approach for undersea image based on function transformation is presented. The approach overcomes the influence of complex environment and uneven illumination effectively. Experimental results demonstrate that the approach is valid for target segmentation and feature extraction for undersea hydrothermal vent image.
