OpenCV Detection of Dark Objects Against Light Backgrounds
The results of some experimentation with and comparison between raw OpenCV functions and the cvBlobsLib library to detect darker coloured spots against lighter backgrounds. (more…)

Object Detection Using the OpenCV / cvBlobsLib Libraries
A short example of how to utilize various open source library functions that can be used to identify and analyse strongly connected components for a given input image.
In the example I have given here, the image represents microarray sample spots printed to a slide using a Xaar inket printer. Using our robotic equipment, a camera is mounted to the printhead, so that images are taken of the spots, as they are being printed on-the-fly, usually in linear groups of 12 or 32 at a time: (more…)
