API Modules � � � � core - a compact module defining basic data structures, including the dense multi-dimensional array Mat and basic functions used by all other modules. imgproc - an image processing module that includes linear and nonlinear image filtering, geometrical image transformations (resize, affine and perspective warping, generic table-based remapping), color space conversion, histograms, and so on. video - a video analysis module that includes motion estimation, background subtraction, and object tracking algorithms. calib 3 d - basic multiple-view geometry algorithms, single and stereo camera calibration, object pose estimation, stereo correspondence algorithms, and elements of 3 D reconstruction. features 2 d - salient feature detectors, descriptors, and descriptor matchers. objdetect - detection of objects and instances of the predefined classes (for example, faces, eyes, mugs, people, cars, and so on). highgui - an easy-to-use interface to video capturing, image and video codecs, as well as simple UI capabilities. gpu - GPU-accelerated algorithms from different Open. CV modules.

如何製作自己的Object Detector 1. 2. 3. 4. 5. 6. Collect a database of positive samples and a database of negative samples. Mark object by objectmarker. exe Build a vec file out of positive samples using createsamples. exe Run haartraining. exe to build the classifier. Run performance. exe to evaluate the classifier. Run haarconv. exe to convert classifier to. xml file
