Montanari [4] has investigated a type of quasi-Euclidean distance mapping. The distance between two points is defined as the length of the shortest chain-coded path and each step of the path can, in the simplest case (order 1), be selected from the 4 possible steps in the d 4 neighborhood. computation, and image segmentation [2]. Distance transform algo- rithms are excellent tools for a variety of applications, such as image processing, computer 

Euclidean distance is consequently a candidate because, representing images as points in a high dimensional Euclidean space, the so-called image space, is a common starting point of most recognition algorithms.

Glossary - Distance Metrics Distance Metrics It is often useful in image processing to be able to calculate the distance between two pixels in an image, but this is not as straightforward as it seems. The presence of the pixel grid makes several so-called distance metrics possible which often give different answers to each other for the distance between the same pair of Distance transform of binary image - MATLAB bwdist D = bwdist(BW) computes the Euclidean distance transform of the binary image BW.For each pixel in BW, the distance transform assigns a number that is the distance between that pixel and the nearest nonzero pixel of BW.. You optionally can compute the Euclidean distance transform of a 2-D binary image using a GPU (requires Parallel Computing Toolbox™). (PDF) A fast algorithm for computation of discrete ...

1)Euclidean distance is calculated as the square root of the sum of the squared differences between a new point (x) and an existing point (xi) across all input  CHAPTER 4 4. METHODS FOR MEASURING DISTANCE IN … from the nearest boundary and is an important tool in computer vision, image processing and pattern recognition. In the distance transform, binary image specifies the distance from each pixel to the nearest non-zero pixel. The euclidean distance is the straight-line distance between two pixels and is evaluated using the euclidean norm. On the Euclidean Distance of Images R2 - AMiner On the Euclidean Distance of Images Liwei Wang, Yan Zhang, Jufu Feng Center for Information Sciences School of Electronics Engineering and Computer Sciences, Peking University Beijing, 100871, China {wanglw, zhangyan, fjf}@cis.pku.edu.cn Abstract We present a new Euclidean distance for images, which we call IMage Euclidean Distance (IMED). Evaluation of Euclidean and Manhanttan Metrics In Content ... Two different distance metrics, via, Euclidean distance and Manhattan distance, are used in two color spaces, RGB and HSV. Firstly apply the color image conversion, i.e., in the form of RGB. One must have to apply the color conversion technique first with the help of color model, i.e., HSV (Hue, Saturation, and Value).

In this method, the number of clusters is initialized and the center of each of the cluster is randomly chosen. The Euclidean distance between each data point and all the center of the clusters is computed and based on the minimum distance each data point is assigned to certain cluster.
