WebContour area is given by the function cv2.contourArea () or from moments, M [‘m00’]. area = cv2.contourArea(cnt) 3. Contour Perimeter ¶. It is also called arc length. It can be found out using cv2.arcLength () function. Second argument specify whether shape is a closed contour (if passed True ), or just a curve. WebImage Data. Image data is passed to and from NPPI primitives via a pair of parameters: A pointer to the image's underlying data type. A line step in bytes (also sometimes called line stride). The general idea behind this fairly low-level way of passing image data is ease-of-adoption into existing software projects: WebSelects ROI on the given image. Function creates a window and allows user to select a ROI using mouse. Controls: use space or enter to finish selection, use key c to cancel selection (function will return the zero cv::Rect). bj and the bear wheels of fortune
