Computer Vision & Image Processing Tutorials
WebGL (Web Graphics Library) is a part of HTML5 browser features. The technology allows usage of OpenGL ES 2.0 capabilities. WebGL is a JavaScript API that allows GPU-acceleration through shader code (OpenGL Shading Language – GLSL). The below tutorials describe how to do online image processing and filtering by HTML ‘canvas’ element and WebGL graphics.
The Median filter is a nonlinear noise reduction filter that is widely used in image processing. It is very effective in cases of salt and paper noise (impulsive noise) and […]

The Mean filter is a linear low-pass blur filter where each pixel in the output image has average value of its neighboring pixels in the input image. The algorithm is […]

The Hough Transform is a method to find shapes in an image. The classical transformation is initially designed to identify lines in the image. Later the transform extends to identify […]
