Set of two Arnold Imager plugins that use the Kuwahara Filter to achieve a stylized NPR look.

Use Python packages, like OpenCV, Skimage and Pillow to process digital images

Three different image filters were implemented using OpenCV: Kuwahara filter, Gaussian filter, and Mean filter.

Developing an artistic abstraction of photo-realistic images using the Kuwahara filtering technique

NPR Studio is a WebGL-powered web solution for stylizing images with traditional Non-Photorealistic Rendering techniques.

The Kuwahara filter is a non-linear filter used for image smoothing while preserving edges. It divides the image into overlapping square regions and computes the mean and variance of pixel values within each region. Then, it selects the region with the smallest variance and replaces all pixels within that region with the mean value of those pixels.

This project implements the Kuwahara filter, a non-linear image smoothing algorithm designed to preserve edges while reducing noise. Developed in C, it includes versions for both PC and embedded systems, processing grayscale images in the PGM format.
