Intro2Robotics: Connected Components in a Binary Image
Often in machine vision we’d like to know how many objects are in our camera image. This video illustrates a popular algorithm that requires just two raster scans through the image, from Chapter 11 in \”Robot Modeling and Control\” by Spong, Hutchinson, \u0026 Vidyasagar. We first convert the image to greyscale, apply a threshold value chosen to minimize the withingroupvariance, and then apply two raster scans to first assign labels to object pixels while generating an equivalency list, then a second raster scan to relabel all components according to the equivalency list.
Note: this video reveals that Fig. 11.3 is actually a dead dinosaur under a comet.
The image used is imRGB below, the thresholded values are imBW, the connected components are cc:
