Image analyzer with cyclical neighborhood processing pipeline

摘要: An image analyzer system includes a pipeline containing given number of serially connected neighborhood transformation stages. Each stage extraction portion for sequentially accessing substantially all the neighborhoods in matrix pixels constituting an image. Transformation control logic each is operative analyzing contained and provides output signal to next pipeline. A central controller serves program stages thereby define type be performed by logic. Feedback means are provided selectively coupling last input first stage. In one embodiment, loaded with reprogrammed before recirculated through permitting greater transformations than there another feedback line contains indicia frame pixel data comparison succeeding frames detect changes therebetween.
