List of image filters from computer vision and image analysis. Photo filtering for image analysis and processing online photo filtering and enchantment
Symmetric Nearest Neighbor Filter
The Symmetric Nearest Neighbor Filter (SNN) is a non-linear edge preserving image processing filter. It is a very effective noise reduction technique that removes noise while maintaining sharp image edges. …
Median Filter – edge preserving filter tutorial
The Median filter is a nonlinear noise reduction technique that is widely used in image processing. It is very effective in cases of salt and paper noise (impulsive noise) and …
Mean Filter: Box blur for fast noise reduction
The Mean filter is a linear low-pass blur photo filter where each pixel in the output image has average value of its neighboring pixels. The algorithm is also famous as …
Gaussian Blur – Noise Reduction Filter
Gaussian blur is an essential part of many image processing algorithms. It serves to clear the noise in the images, as well as a general visual effect in various graphics …
