Now we are getting into the actual function which is selectROI(). And store it in a variable to access it in the future for further manipulations. NumPy library plays a very crucial part in this program because OpenCV uses NumPy as the backbone to do all image manipulations.īefore doing all sorts of functions in an image it is obvious to read the image first. First of all, we need to import the required libraries which in our case it is OpenCV and NumPy. We can also draw a tracking figure(rectangle) on the area using the coordinates or we can precisely and freely crop an image. We can pass that particular area as an input for another task. Using this function in OpenCV, we can precisely and manually select the area of interest we needed from the image and hence we can perform many tasks for that specific area.

fromCenter: if true origin of selection will match initial mouse position.

showCrosshair: if true crosshair of the selection rectangle will be displayed.

window_name: name of the window where selection process will be shown.
