A method for segmentation of color images and contour detection (Q1980286)

This article focuses on segmenting color images of water sources and detecting contours of the water sources. Based on the observation that, on the blue channel, the water area in the image is darker, a threshold algorithm identifying the blue pixels is presented to solve the problem. The algorithm has been tested on four images of different sizes and resolutions to show its effectiveness. To show the practicality of the algorithm, it is expected to do experiments on more color images and also check the effects of selected thresholds on results.
