Extracting Shapes From Images Using Opencv And Python
Extracting Shapes From Images Using Opencv And Python. The operations to perform using opencv are such as segmentation and contours, hierarchy and retrieval mode, approximating contours and finding their convex hull, conex hull, matching contour, identifying shapes (circle, rectangle, triangle, square, star), line detection,. I'm extracting shapes from images and, if a shape is too big (according to some features like area, for instance) then i extract this shape and analyse it separately.

The operations to perform using opencv are such as segmentation and contours, hierarchy and retrieval mode, approximating contours and finding their convex hull, conex hull, matching contour, identifying shapes (circle, rectangle, triangle, square, star), line detection,. So, the issue here is that i am not getting why the findcontours() function for python3 version of opencv returns a null hierarchy and, consequently, no contour is found. In this tutorial we will learn that how to do opencv image segmentation using python.
