WebMassachusetts Institute of Technology WebMar 11, 2024 · Abstract: We observe a common characteristic between the classical propagation-based image matting and the Gaussian process (GP)-based regression. The former produces closer alpha matte values for pixels associated with a higher affinity, while the outputs regressed by the latter are more correlated for more similar inputs. Based on …

WebClosed Form Matting. Customized implementation of the closed form matting alogrithm which is proposed by A. Levin 。. This is an alogrithm for image matting by giving certain constraints, i.e. trimap or scribble. WebClosed-form Matting of “Grayscale” images Assume that both F and B are “approximately constant” over a small window around each pixel. By this assumption equation (1) can be rewritten as ≈ a + b , ∀i ∈ w------------------------------ (2) · a = 1 / F - B · b = -B / F - B · w – small image window 4. Cost function
