DEFINITION

Classification: 382/205

Local neighborhood operations (e.g., 3x3 kernel, window, or matrix operator):

(under subclass 195) Subject matter in which the image under analysis, together with any pattern* therein, is divided into a plurality of generally two-dimensional neighborhoods (also known as windows, sections, or regions), and a computation is executed on each neighborhood based on a local computational algorithm or on a set of mapping operators which transform various qualitative geometric properties of the image into quantitative values.

(1) Note. To be classified herein, the neighborhood operation is for use in the recognition of a pattern*. If a neighborhood operation is used for the transformation of an image or to perform a morphological operation, proper classification is in this class, subclass 209.
