Neighborhood coding is a binary image representation method that has been performing successfully for a variety of applications such as features extraction for image recognition, shape descriptor, and image compression. Despite the success of this coding method, the representation lacked a formal notation. Here, we proposed a formal mathematical notation to represent any binary image into a neighborhood...
A novel coding algorithm for binary images based on neighbourhood relations is used for the problem of handwritten numerals recognition. Each pixel of an image is transformed into a set of representative vectors by coding it according to the number of neighbours in the four directions (north, east, south, west). These neighbourhood vectors are transformed into a set of codes satisfying the boundary...
