Algorithm for Underwater Cable Tracking Using CLAHE based Enhancement

This paper proposes an algorithm for tracking cables from underwater images. The proposed algorithm goes through a pre-processing stage which aims at enhancing the image for facilitating the line detection process. Then the image is segmented using a clustering algorithm and the edges are detected using the Sobel operator. The detected edges are then passed through Hough Transform algorithm for getting the lines. The algorithm has been tested on underwater images having cables with different orientations and is seen that the cable gets tracked, whatever its position be. Cables having different colours on them pose a problem while choosing the number of clusters in the segmentation process. The proposed algorithm can be thus modified by introducing provisions for handling different colours on the same cable.
