Simultaneous projection feature analysis apparatus

摘要

In an apparatus for serially performing simultaneous feature processing and similarity discrimination of an image such as a character or any other figure, an input image is multiplied by a first multiplier into a plurality of optical pattern images which are respectively supplied to means for detecting different types of projection features. The means for detecting different types of projection features simultaneously performs different types of projection operations of the input image. The optical pattern image obtained by converting a vector corresponding to the different types of projection features is displayed on a vector display. The optical pattern image displayed on the display is multiplied by a second multiplier into optical images which are then respectively supplied to different types of reference masks. Optical pattern matching between the optical images from the second multiplier and the different types of reference patterns is simultaneously performed.
