Poisson matting
WebSep 17, 2016 · where \(\alpha \) is the alpha matte for each pixel with range in [0, 1]. Since F, B and \(\alpha \) are unknown, seven variables are to be estimated for each pixel, which makes the original matting problem ill-posed. Image matting techniques [1, 2] require users specify foreground and background color samples with strokes or trimaps as shown in … WebVarious exemplary Poisson matting techniques can be used to generate a high quality matte for use in extracting the koala from the image 100. The extracted image of the koala can then be used, for example, to form a composite image. Various exemplary techniques described herein rely on one or more assumptions.
