This is the filtered picture:

The saturation curve is exponentiated by 2

ExpSat (exp_s=2)

Example:

this is the source picture.

This is the filtered picture:

The saturation of blue areas is enhanced, while that of the yellow-red is exponentiated:

1. ExpSat(hlow=190,hhi=220,exp_s=.5)

2. ExpSat(hlow=220,hhi=60,exp_s=2)

Selection of the blue -> yellow portion

for testing purpose:

1. ExpSat(hlow=220,hhi=60,exp_s=2,
   test=true)

Example:

(Nuragic Launeddas player - X sec B.C. )

This is the filtered picture:

The saturation of red areas is enhanced, while that of the green-blue is exponentiated:

1. ExpSat(hhi=70,hlow=360,exp_s=.7,post_s=1.3)

2. ExpSat(hlow=70,hhi=360,exp_s=3)
