NPR Filters
An image processing tool based on WebGL implemented some Non-photorealistic rendering (NPR) related algorithms. Supported basic image filters (Sobel, Laplacian, Gaussian, Difference of Gaussian (DoG), Bloom). Implemented Line integral convolution, Extended DoG (XDoG), Flow-based XDoG, Kuwahara filter, Generalized Kuwahara filter and Anisotropic Kuwahara filter
