Abstract
Digital image matting is widely used in virtual reality, augmented reality, and film and television production. It is mainly used to solve the problem of separating foreground information from background information. Specifically, it is to solve the value of the unknown pixels between foreground and background information. Digital image matting methods mainly include sampling method and affine method, this paper proposes a sampling method that combines Sparse-Coded and Robust matting algorithm, named SRMatting. The robust algorithm uses a local sparse single-point sampling method at the edge. Sparse-Coded sampling has a lot less color redundancy than dense sampling. Still, local edge sampling has the problem of insufficient depth and breadth color information collection. Therefore, this article combines the Sparse-Coded algorithm (global depth sparse method) with the sampling part of the Robust algorithm to enrich the diversity of samples and adds the preprocessing steps to the new algorithm SRMatting to improve the accuracy of the solution and reduce the amount of calculation.
