Image Segmentation - Auckland

2010-3-8  Region similarity. The uniformity or non-uniformity of pixels to form a connected region is represented by a uniformity predicate, i.e. a logical statement, or condition being true if pixels in the regions are similar with respect to some property (colour, grey level, edge strength, etc).This predicate does not restrict the grey level variation within a region because small changes in signal ...

Connected Component Labelling - GitHub Pages

2016-8-11  Connected Component Labelling (CCL) is a technique used in Image Processing to identify blobs of pixels in an image. A blob, or connected component, is an area of connected foreground pixels: a single shape made up of a continuous mass of pixels, where from any pixel inside it you can travel to any other pixel inside it, without ever leaving ...

How to implement region growing algorithm? - OpenCV

2015-6-3  region_growing. imageprocessing. asked Jun 3 '15. RB. 90 2 6 10. I want to use the Region Growing algorithm to detect similar connected pixels according to a threshold. I have also check some posts in the web but non of them offered a pseudo code for an example. I am also wondring if that algorithm is implemented in opencv library?

Region growing is an image segmentation algorithm. It ...

Region growing is an image segmentation algorithm. It examines neighboring pixels of initial seed points and determines whether the pixel neighbors should be added to the region. The region is iteratively grown by comparing all unallocated neighboring pixels to the region. The difference between a pixel's intensity value and the region's mean ...
