WebSparse Coding for Alpha Matting . Existing color sampling based alpha matting methods use the compositing equation to estimate alpha at a pixel from pairs of foreground (F) and background (B) samples. The quality of the matte depends on the selected (F,B) pairs. In this paper, the matting problem is reinterpreted as a sparse coding of pixel ... Websum of the sparse codes for F pixels directly provides the a. Initially, the pixels in the trimap are classified into high-confidence and low-confidence based on probabilistic segmentation.
