2. How do you find the coordinates of a contour?
3. How do you check if a point lies inside a contour OpenCV?

How do you find the contour area in OpenCV?

Contour area is given by the function cv. contourArea() or from moments, M['m00'].

How do you find the coordinates of a contour?

The Co-ordinates of each vertices of a contour is hidden in the contour itself. In this approach, we will be using numpy library to convert all the co-ordinates of a contour into a linear array. This linear array would contain the x and y co-ordinates of each contour.

How do you check if a point lies inside a contour OpenCV?

To determine if a point is inside, outside, or on the edge of a shape you can check if the point is within a contour using cv2. pointPolygonTest() . The function returns +1 , -1 , or 0 to indicate if a point is inside, outside, or on the contour, respectively.
