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 …
Hough Transform – Basic Shape Detection
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 …
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 …
