BaseCascadeClassifierclass

base cascade classifier value in the OpenCV API.

CascadeClassifierclass

example: samples/facedetect.cpp

CascadeClassifier_convertfunction

Convert a legacy Haar cascade file to the newer cascade serialization format in the virtual filesystem.

groupRectanglesfunction

Groups the object candidate rectangles.

HOGDescriptorclass

Implementation of HOG (Histogram of Oriented Gradients) descriptor and object detector.

HOGDescriptor_DescriptorStorageFormatclass

Native enum entries for hogdescriptor descriptor storage format. Pass an entry to enum-typed arguments or its .value to numeric arguments.

HOGDescriptor_getDaimlerPeopleDetectorfunction

example: samples/hog_tapi.cpp

HOGDescriptor_getDefaultPeopleDetectorfunction

Returns coefficients of the classifier trained for people detection (for 64x128 windows).

HOGDescriptor_HistogramNormTypeclass

Native enum entries for hogdescriptor histogram norm type. Pass an entry to enum-typed arguments or its .value to numeric arguments.

Constants
