Tutorials on many image-processing operations



A great collection of tutorials on many image-processing operations:

  • Labeling image pixels — histograms, classification, connected component analysis.

  • Morphology — dilation, erosion, opening, closing, hit-and-miss transform, thinning, thickening, skeletonization and medial axis transform.

  • Digital filters and noice reduction — mean filter, median filter, gaussian smoothing, conservative smoothing, crimmins speckle removal, frequency filters, Laplacian/Laplacian of Gaussian filter (edge detection), unsharp filter.

  • Feature detectors — Roberts cross edge Detector, Sobel edge detector, Canny edge detector, compass edge detector, zero crossing detector, line detector.

  • Image transforms — distance transform, Fourier transform, Hough transform.
