Feature points extraction is a common computer vision task where Harris Corner Detector fits well. Corners are important features of an image, since they provide useful information for objects detection. […]Read: "Feature Points Extraction using Harris Corner Detector"
Color space conversion is transformation from one color representation into another. In image processing this is a common approach for better image representation to help solve certain tasks. There are […]Read: "Color space conversion"
The Skin Detection and Segmentation is a process of finding skin-colored image regions from video frames or still pictures. Typically this is a preprocessing step in the image analysis to find […]Read: "Skin Detection and Segmentation in RGB Images"
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 gradient Non-maximum suppression also known as edge thinning is a process of extracting thin, one pixel wide object’s contours. This process follows gradient detection as a post processing step. […]Read: "Gradient Non-Maximum Suppression"
The Sobel filter (also called Sobel-Feldman operator) is an edge detection filter, that results in image emphasizing edges. Computer vision and image processing applications frequently use this filter to extract image […]Read: "Sobel Filter – Sobel-Feldman Edge Detection and Gradient Extraction"
