Frequently in image processing an unknown image is identified by matching features from the image to features of known images. One method of doing this is to compute a distance measure between the features of the two images. This measure indicates the dissimilarity between the images. This distance measure is computed for each of a large set of different known images. The process of exhaustively locating the known image with the minimum distance, and therefore the best match is called nearest neighbor matching.
The aim of the edge thinning process is to remove the inherent edge broadness in gradient images while retaining edge continuity of the image. Such a process is required so that a useful silhouette of the target can b...

An analysis of the statistics of the moments and the conventional invariant moments shows that the variance of the latter become quite large as the order of the moments and the degree of invariance increases. Moreso, ...

A system which accepts a two-dimensional scene as input and produces an image of the scene as output introduces degradations to the image which cause a loss of information about the original scene. A mathematical mode...
