摘　　要：在遥感影像的处理过程中,针对遥感影像各瓦片数据生成的快视图之间存在色差的问题,通过对整景影像数据和各瓦片数据进行分析,在采用2%线性拉伸算法进行影像处理的基础上进行改进,提出使用共享直方图信息的策略来进行快视图的生产,即用整景影像的直方图信息代替各瓦片直方图信息来决定各瓦片应去除的像素点,然后再对瓦片剩余像素点的灰度值进行线性拉伸,以此来达到减小各快视图之间色差的目的。In the process of remote sensing images processing,in order to reduce the Chromatic aberration among the quick-views of different tiles of remote sensing image,through comparison and analysis of the data of remote sensing image and tiles,proposes a new strategy based on 2%-linear-stretch algorithm and histogram sharing.The main idea of this strategy is to use the histogram of the whole image to replace the histogram of the tile to determine the pixels should be moved in tile,and then stretch the gray value of remain pixels.This strategy aims to reduce the Chromatic aberration among the quick-views.
