WebDec 1, 2024 · 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. Here, in the image above we can see several different shapes. WebJun 17, 2013 · If the contours of the shapes are discriminative enough, you can try shape context. To classify shapes, feed in these features into any classifier -- SVM or random forests for instance.
