Hello there!
How can i achieve some color enhancements with the Intels IPP library?
I'm working with RGB32 images and in particular would like to:
- Raise/lower the single "RGB channels"
This could this be achieved via "Image Arithmetic and Logical Operations", i think.
Just "Add"/"Sub" values from RGB channels. Right?
- Adjust "color temperature"
Not sure about this, but i red some advices to devise my own stratagy, changing the color between red and blue.
Any idea/comments about the most common/practical way to do it?
- Raise/lower "black color" value
Well i suspect the color space conversion to HLS and adjsuting the "lightness" (L) value, than back to RGB?!?!
- Adjust "color saturation"
color space conversion to HLS and adjsuting the "saturation" (S) value, than back to RGB?
- Gamma correction
Isn't the same as "adjustment of black color"?!?!
- Adjust "contrast"
A combination of simultaneously admjustment of "saturation" and "lightness"?
higher contras -> higher saturation + lower lightness ?
lower contras -> lower saturation + higher lightness ?
Thank You very much in advance!
Regards,
Max
