I'm looking for a filter in openCV library that change the image chromatically. For example, the blur does not change the colors of the image, I need one that do it.

I got a colored image, I need to apply a filter that distorts the color. For example, if I have an image with a lot of blue, with this filter this blue will be less or more intensity.

My images are in L* a* b* colour space and I need to work in it.

Please be more specific/precise about your goals and show what you have tried so far. Thanks. – Mark Setchell Feb 06 '19 at 13:59
Added more explanation, I have not found anything to do that... – Davide577 Feb 06 '19 at 14:02
Look here at HSL and consider selecting blues and increasing saturation... https://en.m.wikipedia.org/wiki/HSL_and_HSV – Mark Setchell Feb 06 '19 at 14:08

I need to work in L*a*b* color space, there is not a filter such as blur that change colors? And I need to do that with various intensities. – Davide577 Feb 06 '19 at 14:12
If you already know you need to work in **Lab** colourspace you are clearly able to improve the quality of your question... so that would be a good place to start getting help. – Mark Setchell Feb 06 '19 at 14:25
Ok, I updated the question. – Davide577 Feb 06 '19 at 14:34
It's not really a filter that you need. You just need to apply a function that decreases the **a** and/or increases the **b** if you want to decrease the blue component. – Mark Setchell Feb 06 '19 at 15:01
