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.
