The shape context is intended to be a way of describing shapes that allows for measuring shape similarity and the recovering of point correspondences. The basic idea is to pick n points on the contours of a shape. For each point pi on the shape, consider the n − 1 vectors obtained by connecting pi to all other … See more Shape context is a feature descriptor used in object recognition. Serge Belongie and Jitendra Malik proposed the term in their paper "Matching with Shape Contexts" in 2000. See more Step 1: Finding a list of points on shape edges The approach assumes that the shape of an object is essentially captured by a finite subset of the points … See more • Matching with Shape Contexts • MNIST database of handwritten digits • Columbia Object Image Library (COIL-20) • Caltech101 Database See more A complete system that uses shape contexts for shape matching consists of the following steps (which will be covered in more detail in the Details of Implementation section): 1.
