Class Information
Number: 382/266
Name: Image analysis > Image enhancement or restoration > Edge or contour enhancement
Description: Subject matter wherein processing is done to visually enhance the outlines of individual characters or objects of interest in the image by emphasizing high frequency, transitional image data while deemphasizing or removing low-frequency, homogeneous background image data.

Sub-classes under this class:

Class Number Class Name Patents
