Nettet3.1. HOG implementation details We have implemented the Histogram of Oriented Gradi-ents (HOG) as formulated in [8]. Given an input image (of size M N), the main parts of the HOG computation are as follows 1. Compute image gradient in X and Y directions. 2. Determine the best orientation (among 18 ﬁxed orien-tations) of the gradient at each ... NettetTo use the FHOG extractor you just need to create the object: HogFeature FHOG (cellSize, scale); After that you obtain the FHOG features from your image like this: cv::Mat features = FHOG.getFeature (image); Results The out.avi shows the performance of the presented FHOG extractor when used to detect cars (using a SVM classifier).
