Imadjust g=imadjust(f,[low_in,high_in],[low_out,high_out],gamma) Includes various contract transformations. Chapter 3
Intensity Transformations and Spatial Filtering Logarithmic and Constrast Transformations
g=c*log(1+double(f)) gs=im2uint8(mat2gray(g)); % to range [0,1] and to gray scale Contrast transformation g=1./(1+(m./(double(f)+eps)).^E) Use of eps prevents overflow if f has any zero values
m is turning point Chapter 3 Intensity Transformations and Spatial Filtering
Stem and plot Find out syntax from typing help stem and help plot in MATLAB.
Chapter 3 Intensity Transformations and Spatial Filtering Histeq command
g=histeq(f,hspec) hspec is a specified histogram. If you do g=histeq(f,256) you get histogram equalization.
