ABSTRACT:
Attributes or features of a portion of a picture are represented by one or more strokes which are formed using special purpose hardware and a processing algorithm which operates in a hypothesize-and-test mode. Each assumed stroke is tested using parallel processing, and the test result is used to determine the next hypothesis. A minimum of information is maintained indicating prior test results.
