Splet12. mar. 2024 · Our PLADE-Net is based on a new network architecture with neural positional encoding and a novel loss function that borrows from the closed-form solution of the matting Laplacian to learn pixel-level accurate depth estimation from stereo images. Spletpymatting.laplacian.laplacian module. This function constructs a linear system from a matting Laplacian by constraining the foreground and background pixels with a diagonal matrix C to values in the right-hand-side vector b. The constraints are weighted by a factor λ. The linear system is given as.

Splettors of the Matting Laplacian, while our framework admits a larger set of solutions. Although we have motivated the need for a framework for alpha matte estimation for multiple layers, our pre-sented analysis can also be applied to problems other than alpha matting.
