| Abstract(in English) | Vector Median Filters (VMF) that consider the correlation among the color components are often used for impulse noise removal. In addition Switching VMFs (SWVMFs) have been proposed to improve the preservation of pixel values in noncorrupt pixels. The filtering performance of SWVMFs depends on not only the accuracy in the filtering step but also the accuracy in the noise detection step, therefore, the estimation of a suitable window shape for the noise detection step in SWVMFs is one of important problems. In this study, for color textures, we formulate the design of the noise detector for SWVMFs as an optimization problem, and estimate optimal shapes directly from degraded images. Numerical experiments show that designed noise detectors outperform general filtering shapes. |
