which function in openmv is close to cv2.approxPolyDP of opencv?
how about the minEnclosingCircle、fitEllipse of opencv？
Hi, see find_blobs() and it’s outputs. There’s really no contour support, though, onboard.
i want to get the vertex coordinate of shape. 
We have this: image — machine vision — MicroPython 1.24 documentation
Which you can use to get the enclosing circle or ellipse.
thank you，i want to get the three vertex of triangle shape
