Example :

This is the source picture

First step

First filtering step:

The image high tones are toned to yellow

Colorize (exp_l=3,rf=100,gf=100)
Second step

Second filtering step:

The image low tones are toned to violet

Colorize (exp_l=-3,bf=-50)

 

Source Filtered

Example:

the same steps applied to a color image.

Testing ..

Testing : saturation factor (in green)

for testing purpose (exp_s=.4):

 

  1. Colorize
    (ga=0,exp_s=.2,rf=200)
Filtered

Subtracting blue (bf=-200) in image dark tones with enhanced source weight (ga=1.2) and saturation exp factor of 0.4

 

  1. Colorize (ver,exp_s=.4,exp_l=-3,
    bf=-200,ga=1.2)
Filtered

The same image without

saturation factor

 

  1. Colorize (ver,exp_l=-3,
    bf=-200,ga=1.2)
