WebFast Weighted Median Filter Weighted median is used in many of computer vision applications for its properties in sparsity representation. We re-implement an efficient algorithm to reduce computation complexity from O(r2) to O(r) where r is the kernel size. Web4 de jan. de 2024 · Bilateral Blur: A bilateral filter is a non-linear, edge-preserving, and noise-reducing smoothing filter for images. It replaces the intensity of each pixel with a weighted average of intensity values from nearby pixels. This weight can be based on a Gaussian distribution. Thus, sharp edges are preserved while discarding the weak ones.
