## Sobel Operator

The Sobel operator is an algorithm for edge detection in images. Edge detection for those who are not familiar with the term, is an image processing technique to discover the boundaries between regions in...

## Detecting corners of image using Non-Maximum Suppression

Non-maximum supression is often used along with edge detection algorithms. The image is scanned along the image gradient direction, and if pixels are not part of the local maxima they are set to zero....

## Color depth

Color depth is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color...

## Euclidean distance

The Distance Formula Very often, especially when measuring the distance in the plane, we use the formula for the Euclidean distance. According to the Euclidean distance formula, the distance between two points in the...

## connectivity and path

Paths A path from pixel p with coordinate (x, y) with pixel q with coordinate (s, t) is a sequence of distinct sequence with coordinates (x0, y0), (x1, y1), ….., (xn, yn) where :...

Two pixels p and q with values from V are m-adjacent if :   1. q is in the set N4(p), or 2. q is in the set ND(p) and the set N4(p)∩N4(q) has...
