Class Information
Number: 382/210
Name: Image analysis > Pattern recognition > Template matching (e.g., specific devices that determine the best match) > Spatial filtering (e.g., holography)
Description: Subject matter in which an optical image of each pattern* to be recognized is transformed into a light amplitude distribution that is proportional to the two-dimensional Fourier transform of the pattern* image, and a spatial filter located in the transform plane modifies selected Fourier components of the resulting Fourier spectrum.
