in photoshop if you try to cut out at the middle of the edge, the edges look rigid. If you let anitaliasing in the selection that you are trying to extract, you get background color mixed. Which doesn't let it be on other colors.

So i know programitacially it's possible to extract transparency, like see immediate color of background, use that to calculate transparency of anti aliasing pixels and calculate and then use that.

But i can't think of a way doing it in photoshop this always leads to a dead end and lots of work. this is no problem is image is very high definition. Because even hard edge looks clean edge. Possible ways include cutting at hard edge but than fading edges. But this isn't a solution and not a possibility in all situations.

Or do it your way: extract this cat and bring it to red or white background. enter image description here

hi, did you try using Layer > Matting ? There is few options depends on what color was the background. E.g. when you are extracting something from white background you should use Remove white mate on layer with extracted object etc... –  Lukaydo Oct 30 '13 at 13:16
    
i didn't know of that..thanks..this is like approaching a problem in reverse instead of extracting color neutral transparency we turn transparency of extruded image white or black. –  Muhammad Umer Oct 30 '13 at 18:07
    
i tried it but it works like only 50% time with some accuracy. Other times meh. –  Muhammad Umer Oct 30 '13 at 18:46

Questions which ask for answerers to make modifications on a specific image are frowned upon because it sets a precedent of doing free work for people. If you remove the request for citizens to work on a specific image, and just use the image as an example of the kind of thing you're talking about, this question will be much better for it. –  BESW Oct 30 '13 at 19:48
    
you realize picture was added after days. I asked for something but someone commented on a different approach now that it's clear other approaches accomplish what i want i put an image that can be clear example of what i want. So if others post any technique because of this image it'd be sure to be the one that i am looking for. There is big or in question. Image is meant to remove confusion. But if you don't like it then why bother. And not just answer the question if you can. –  Muhammad Umer Oct 30 '13 at 20:26

Short, best, only accurate method in my opinion is to get as close as possible with traditional methods, then grab a brush and paint on a mask. There's no substitute for the human eye. No automated process can determine what is visually more striking. While a 10% grey pixel may be needed for one image, it may not be needed for the next. Software can't make that distinction - it merely sees a 10% grey pixel.

Quality work takes expert craftsmanship. If everything could be automated, people would no longer be needed.
