对多分辨率彩色图像进行增强。

使用multibandread函数读取Erads lan格式的多分辨率数据；使用对比度拉伸函数imadjust增强图像；使用去相关拉伸增强函数decorrstretch增强图像-Multi-resolution color image enhancement. A multi-resolution data to use the multibandread the function reads Erads lan formats　enhanced image contrast stretching function imadjust　using the decorrelation stretch enhanced function decorrstretch enhanced image
