What is chessboard distance in image processing?
The chessboard distance metric measures the path between the pixels based on an 8-connected neighborhood. Pixels whose edges or corners touch are 1 unit apart. Quasi-Euclidean. The quasi-Euclidean metric measures the total Euclidean distance along a set of horizontal, vertical, and diagonal line segments.
How do you find the distance between two pixels?
P(x , y), q(s , t) The Euclidean distance is the straight- line distance between two pixels. City Block P(x , y), q(s , t) The city block distance metric measures the path between the pixels based on a 4- connected neighborhood. Pixels whose edges touch are 1 unit apart and pixels diagonally touching are 2 units apart.
What is adjacent pixels?
In this approach, groups of adjacent pixels in a neighborhood wherein the value of a specific feature (intensity, texture, etc.) remains nearly the same are extracted as a region. Region growing, split and merge techniques, or a combination of these are commonly used for segmentation.
How do you measure the distance of a chess board?
On a chess board, where one is using a discrete Chebyshev distance, rather than a continuous one, the circle of radius r is a square of side lengths 2r, measuring from the centers of squares, and thus each side contains 2r+1 squares; for example, the circle of radius 1 on a chess board is a 3×3 square.
