摘　　要：将适用于全色遥感影像的线性增强技术直接应用到海岛礁彩色遥感影像增强处理中,实现了一种高速地具有色彩保持特性的海岛礁彩色遥感影像增强方法。将其与传统直方图方法、基于直方图的色调不变增强方法进行了对比实验,实验结果表明该方法不但有效改善了海岛礁彩色遥感影像视觉质量,还保持了海岛礁彩色遥感影像的色彩信息。此方法处理的海岛礁彩色遥感影像具有视觉效果好、色彩鲜明等特点,更有利于其后续处理。This paper introduced the linear enhancement scheme for grey scale images to color island image enhancement,which realized a hue invariability color island image enhancement quickly.Compared with color image enhancement methods such as traditional histogram equalization,the method of hue invariability based on histogram equalization,the experiment results demonstrate that the method discussed can not only improve visual effect,but also keep hues information of the color island image.Color images enhanced by this method own good visual effect,richness in color and become much more convenient for image processing.
