Binary shape analysis in computer vision
WebBinary images need only a single bit to represent a pixel value. These images are commonly used as masks for selecting or removing a certain region of an image. It is … WebBinary images are extensively used for document analysis and even in industrial machine vision tasks. Here is a sample binary image: Figure 2.37: QR code as an example of a binary image. Now, let's see how we can convert an image into a binary image. This technique comes under the category of thresholding.

In the second part, we analyze both classification and matching of binary shapes using SIFT and Bag of Features.
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.
