The Symmetric Nearest Neighbor Filter or Symmetric NN filter is a non-linear edge preserving image processing filter. It is a very effective noise reduction technique that removes noise while maintaining sharp […]Read: "Symmetric Nearest Neighbor Filter"
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 […]Read: "Median Filter – Edge Preserving Filter"
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 […]Read: "Mean Filter for Fast Noise Reduction"
The goal of this tutorial is to reveal major details about Gaussian blur and how to use it for image processing and machine vision tasks. FivekoGFX implements a WebGL version […]Read: "Gaussian Blur – Noise Reduction Filter"
