imadjust

调整图像亮度函数

J IMADJUST(I,[LOW_IN HIGH_IN],[LOW_OUT HIGH_OUT],GAMMA)

GAMMA默认值为1（线性映射），GAMMA<1——曲线上凸，GAMMA>1——曲线下凹

图像I与图像f的类型一致，任何类型的图像[LOW_IN HIGH_IN],[LOW_OUT HIGH_OUT]取值均在0—1范围内(计算时函数自己转换)-adjust image brightness function imadjust　 J　 IMADJUST (I, [LOW_IN　HIGH_IN], [LOW_OUT　HIGH_OUT], GAMMA)　GAMMA default is 1 (linear mapping), GAMMA < 1　on convex curve, GAMMA>　1- concave curve　identical to the type of image I and the image f, any type of image [LOW_IN　HIGH_IN], [LOW_OUT　HIGH_OUT] values are in the range of 0-1 (when calculating the function to convert their own)
