Abstract: The disclosed embodiments include an apparatus implemented in a semiconductor integrated chip. The apparatus is configured to operate a composite function, comprising a first function and a second function, on a first patch of an image. The apparatus includes a first function operator configured to operate the first function on the group of pixel values to provide a first processed group of pixel values. The apparatus also includes a delay system configured to maintain the first processed group of pixel values for a predetermined period of time to provide a delayed processed group of pixel values. The apparatus further includes a second function operator configured to operate a second function on at least a second processed group of pixels and the delayed processed group to determine an output of the composite function.

Abstract: The present application provides a method of corner detection and an image processing system for detecting corners in an image. The preferred implementation is in software using enabling and reusable hardware features in the underlying vector processor architecture. The advantage of this combined software and programmable processor datapath hardware is that the same hardware used for the FAST algorithm can also be readily applied to a variety of other computational tasks, not limited to image processing.
