In the below example, the main set of functions is called within a callback function, as this allows the threshold value to be controlled from a GUI in OpenCV. importcv2ascvfromicondetection.demo.demoimportrender_rectangles,candidate_rectangle_demofromicondetection.boximportgrayscale_blur,canny_det...
1. Detect faces in an image In this first example, we will provide an image to FaceDetect and it will draw rectangles around the faces it finds in the image. # Tell FaceDetect to use mode imagefacedetector=FaceDetect({'mode':'image'})# Tell FaceDetect to start detections on a desired...
(bounding boxes and labels). Then it extracts the annotations using theextract_xml_informationfunction and stores them in adictionary. Afterwards, the image is loaded with thecv2.imreadmethod from theOpenCVlibrary. The image and its bounding boxes are resized to the requiredtarget sizeof the ...
