APPLICATION OF CONTRAST ENHANCEMENT AND VISUAL SALIENCY OPTIMIZATION METHOD IN GOLF COURSE IMAGE

摘要

The present invention provides an image contrast enhancement and visual saliency optimization method and the application thereof to a golf course, the method comprising the following steps: obtaining an original realistic image of a golf course, and decomposing the original image into RGB three-channel colour images, i.e. three images in total; after the obtained original realistic image of the golf course is subjected to image smoothing, sharpening, and contrast enhancement, merging same into a realistic colour image of the golf course; and determining, according to requirements, whether the desired visual effect for the image has been achieved, and if the desired visual effect for the image has been achieved, finally obtaining a realistic image with enhanced contrast and optimized visual saliencyd, and if the desired effect is not achieved, decomposing the image into the RGB three-channel colour images, and repeating the above processing process, so that the image of the realistic image of the golf course is clear and the edges are obvious. The visual effects, such as fairways, long grass, greens, sandpits, and trees in the golf course, are significantly improved, and a realistic image, which has a higher contrast and a better visual effect, of the golf course is obtained.
