摘　　要：针对基于小波分析的图像增强技术一般只适用于黑白图像,而伪彩色处理技术不能够充分处理图像中某些细节信息的缺陷,提出基于小波分析和伪彩色的遥感图像增强处理方法。增强后的遥感图像无论在视觉效果上还是在噪声特性上都有了很大的改善。该方法简便易行,计算量小,在应用中有较大的灵活性。该方法还具有运算速度快,可操作性强等特点。在遥感图像增强研究方面具有广泛的应用前景。Method of remote sensing image boosting which aim at lacuna of technology of image boosting based on wavelet analysis which can commonly deal with black and white image and fake chromatic processing can＇t adequately dispose some detail messages of image based on wavelet analysis and fake chromatic processing is put forward. Boosted remote sensing image has gotten improvement commendably either in vision effect or in characteristic of yawp. This method can execute simply and its workload is little and it can apply actively. This method possesses peculiarities of quick operation rate and better maneuverability and it has broad application foreground in remote sensing image boosting.
