How to desaturate background. Help needed.

[schwarzwals]

Guys I need your help figuring this one out.

I want to desaturate the background around the person. There's a lot of blue in it. How can I do that ? I have a lot of files like this.
Would appreciate some examples.

hi, I think you can try u2net (human segmentation model, for human overall shape segmentation) + pymatting (https://github.com/pymatting/pymatting, for getting hair matting) to achieve an relatively high quality alpha channel and then the background can be tuned or changed based on the alpha channel.

or you can use rmbg directly: https://github.com/danielgatis/rembg, to see if that satisfies your requirements.

@xuebinqin I don't want to remove the background....i want to desaturate it...it has a lot of blue/magenta in it...and I thought that if you can have a good mask of a human, invert it and desaturate the rest....don't touch the human...is this possible ?

[xuebinqin]

yes, that is possible. human segmentation can be used to desaturate or change the color of the human and non-human regions based on your demands. Otherwise, your whole image will be desaturated which is probably not what you want.
