摘　　要：台风云图增强是通过增加图像的对比度和色彩,增加台风的可视化,为后续预测路径和图像分割提供准确的图像。文章提出一种有效的增强台风云图对比度的方法,首先对输入图像进行反相操作和梯度处理,获取梯度域和取反的图像信息,增加台风云图的细节信息;其次,使用一个简单有效改进直方图的模型来生成分布函数,增强图像的对比度;最后,通过对增强后的图像进行融合,得到最终的增强台风云图。与几种增强方法相比,文章提出的方法获得了更好的主观结果和客观评价。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.
