How to Detect Shapes in Images in Python using OpenCV?

Webb1 dec. 2024 · So, to detect shapes we first need to analyze and understand the contours of that shape. The easiest way to do that is to use binary images (the object that we need to detect should be white and the background should be black). Hence, to detect contours we need to apply threshold or Canny edge detection. Let’s take a look at the following image. If you want to create a border around an image, something like a photo frame, you can use cv.copyMakeBorder().
