Analysis of a composite domain typhoon cloud map enhancement algorithm
Typhoon cloud map enhancement is to increase the visualization of typhoon by increasing the contrast and color of images,to provide accurate image for the subsequent prediction path and image segmentation.This paper proposes an effective method to enhance the contrast of typhoon cloud map,first,the input image for reverse phase operation and gradient processing,obtain the gradient domain and reverse image information,increase the detail information of the typhoon cloud map;then use a simple and effective improvement model to generate the distribution function,enhance the contrast of the image;through the enhanced image fusion,to obtain the final enhanced typhoon cloud map.The proposed method achieves better subjective results and objective evaluation than several enhancement methods.
