Today, I want CV2 cut with a ROI (Region Of Interest) of the time,
It is written
result,
Found to be wrong phrase interception img
It should be:
Earlier 纵后 Horizontal
This OK
cv2.selectROI usage:
selectROI(windowName, img[, showCrosshair[, fromCenter]]) -> retval . @brief Selects 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). . . @param windowName name of the window where selection process will be shown. . @param img image to select a ROI. . @param showCrosshair if true crosshair of selection rectangle will be shown. . @param fromCenter if true center of selection will match initial mouse position. In opposite case a corner of . selection rectangle will correspont to the initial mouse position. . @return selected ROI or empty rect if selection canceled. . . @note The function sets it's own mouse callback for specified window using cv::setMouseCallback(windowName, ...). . After finish of work an empty callback will be set for the used window.
selectROI(img[, showCrosshair[, fromCenter]]) -> retval . @overload
It is such, ┏ (^ 0 ^) ┛
