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

Description: This function was written to allow rotation of both X and Y labels without making tricky guesswork about how to rescale the image.
It works on full figures and subplots, and more control over scaling can be obtained by using subplot in combination with XYrotalabel
