| 摘 要： | 提出一种基于小波降噪、多尺度图像分割和颜色传递的遥感图像彩色化增强方法。该方法利用一种多尺度图像分割技术,将图像分割为若干子区域,在子区域之间进行亮度匹配和颜色传递,减少了颜色传递误差,再与采用软阈值方法的复数小波包降噪预处理相结合,来增强遥感图像的细节分辨能力。试验结果证明,基于图像分割和色彩传递相结合的方法,其参考彩色图像不需要与目标图像配准,只要特征、风格相近似,就可以对纹理结构相对较简单的全色遥感图像实现全自动的彩色化增强。彩色化的结果图像在美观程度及目标的可识别度上都有了明显增强。

| Abstract: | This paper presents a newframework of remote sensing images enhancement based on wavelet denoising ,multi‐scale image segmentation and color transfer .A multi‐scale spectral image segmentation algorithm segments images into several sub‐regions .We match luminance and transfer color between the sub‐regions in order to reduce the error .The framework also involves a wavelet denoising preprocess to enhance the ability of distinguishing details of images .The experimental results demonstrate that the method can auto colorize those remote sensing images without registration which have simple textures and structures .The results not only look better in visual but also improve the recognition of objects . |
