WitrynaThis turns the image to black and white, highlighting the points of interest to make the contour-detection algorithm's job easier. Thresholding makes the image's object's border totally white, with the same intensity across all pixels. From these white pixels, the program can now discern the object's edges. 3. Find the Contours.

Witryna24 kwi 2024 · The f indContours function: OpenCV provides us with the findContours function which finds the contours in an image and stores it as a numpy array of coordinate points. The function definition is ... Witrynamethod. Method for approximating the contours. It can take the following values: 'none': stores absolutely all the contour points. 'simple': compresses horizontal, vertical, and diagonal segments and leaves only their end points (the default). 'l1': applies one of the flavors of the Teh-Chin chain approximation algorithm (Teh & Chin, 1989).
