The workshop was part of a larger program of performances and master classes, most of which highlighted an artist working with TouchDesigner (maotik, Theo Groeneboom, Rui Martins) and technical projection experts from Smart Simulation and product specialists from Barco. Most filters that are used for image smoothing are linear low-pass filters that effectively reduce noise but also blur out the edges. The Kuwahara filter can be defined as a non-linear smoothing filter that does not compromise the sharpness of the image or the positions of the edges and is traditionally recognized by this second… Any ideas on how to get the sectors will be greatly appreciated . After loading an image, this code applies a linear image filter and show the filtered images sequentially.

Due to this adaption, directional image features are better preserved and emphasized. σ ：高斯函数的标准差 . This example compares the following mean filters of the rank filter package: local mean: all pixels belonging to the structuring element to compute average gray level.. percentile mean: only use values between percentiles p0 and p1 (here 10% and 90%).. bilateral mean: only use pixels of the structuring element having a gray level situated inside g-s0 and g+s1 (here g-500 and g+500) In this paper, we propose an efficient algorithm to accelerate this filter .
