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. WebFeb 1, 2016 · In computer vision and image processing, image moments are often used to characterize the shape of an object in an image. These moments capture basic statistical properties of the shape, including the area of the object, the centroid (i.e., the center (x, y) -coordinates of the object), orientation , along with other desirable properties. how fast can a lawn mower engine go
