ABSTRACT:
In a vector discrimination apparatus for performing discrimination such as class classification and recognition of a vector consisting of vector components corresponding to features of predetermined information, an optical pattern displayed on a display at a position corresponding to the size of the vector component is optically multiplied by a multiplier to form multiple images each having a substantially identical shape in the vicinities of various types of reference masks, and pattern matching is established between the multiple images and the various types of reference patterns formed on the reference masks. Discrimination such as class classification and recognition of the vector consisting of the vector components corresponding to the features of predetermined information such as a character or the like can be performed at a high speed, although the apparatus configuration is simple and low cost.
