Hello Ion

In your case to pass from one histogram to the other is as easy as multiplying any pixel by a factor.

In a more complex scenario you should have to set a window of your histogram and determine which function to apply, like:

New color = F(Old color)

Remember to use function int Grayscale(const Color& c). The conversion to gray is more adequate Smile

.

PD. The second histogram strange zeros seem to indicate that there is a problem in the conversion program.

Best regards
Iñaki
