提出了一种改进的自适应对比度均衡遥感图像增强方法,首先将图像划分为互不重叠的子块,在计算当前对比度均衡图像子块局部统计参数系数时,引入了一个覆盖该图像子块邻域图像子块的矩形滑动模板,利用模板内图像的局部统计参数计算对比度均衡变换系数。在增强对比度的过程中引入了平滑因子,在增强图像的同时抑制了图像中噪声。遥感图像增强实验结果验证了改进方法的有效性。
An improved adaptive contrast-enhanced remote sensing image enhancement method is proposed. Firstly, the image is divided into non-overlapping sub-blocks. When calculating the local statistical parameter coefficients of the current contrast-balanced sub-block, a sub-block neighborhood Domain image sub-block rectangular sliding template, the use of local statistical parameters within the template image contrast equalization transform coefficients. In the process of enhancing the contrast, a smoothing factor is introduced to suppress the noise in the image while enhancing the image. The experimental results of remote sensing image enhancement verify the effectiveness of the improved method.
