RGB channel Equalixzation for 8-bit & 24-bit

Today,I perform various type of histogram equalization or contrast equalization .These are performed on following type of images:-     

a) 8-bit color

b) 8-bit gs

c) 24-bit color

d) 24-bit gs

Each type of image uses following five methods:

a) b

b) g

c) r

d) rgb ( All together but channel by channel)

e) r+g+b (each separately)

So ,I get total 20 output images for 4 input images which are respectively 8-bit gray scale,8-bit color,24-bit gray scale & 24-bit color image.Output images are in above sequence. Here is the input images & output images:

Input Images

Output Images for first image which is 8-bit grayscale

Output Images for second image which is 8-bit color image

Output Images for third image which is 24-bit grayscale image

Output Images for fourth image which is 24-bit color image
