Description: 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.

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
