[Special Effects] adjgamma DL : 0: 图像预处理-图像去噪方面-滤波器-matlab的实现程序，非常清晰- ADJGAMMA- Adjusts image gamma. function g = adjgamma(im, g) Arguments: im - image to be processed. g - image gamma value. Values in the range 0-1 enhance contrast of bright regions, values > 1 enhance contrast in dark regions. Peter Kovesi School of Computer Science & Software Engineering The University of Western Australia pk @ csse uwa edu au http://www.cs.uwa.edu.au/~pk July 2001 function newim = adjgamma(im, g) if g <= 0 error( Gamma value must be > 0 ) end if isa(im, uint8 ) newim = double(im) else newim = im end rescale range 0-1 newim = newim-min(min(newim)) newim = newim./max(max(newim)) newim = newim.^(1/g) Apply gamma function
