Binary image feature extraction
WebApr 19, 2012 · I'm assuming that all of your 'features' are properly connected (4- or 8-connected). If that's the case, the algorithm you're looking for would fall under the umbrella of connected component labelling. You can implement the two-pass algorithm described … WebApr 5, 2012 · Feature Extraction On the first sight, that Feature Extraction part looks like a good scenario for Hu-Moments. Just calculate the image moments, then compute cv::HuMoments from these. Then you have a 7 dimensional real valued feature space (one feature vector per image).
