“…Objects such as robots and motor vehicles have a well-defined boundary, and edge detection is easier. Earlier attempts to perform image contour extraction using analog circuit techniques were very similar to their digital counterparts [10]. Discrete time sample systems are used, and processing is performed after the outputs of the pixels are sampled and stored in analog form on an S/H circuit.…”

The implementation of real-time edge detection and image segmentation using analog VLSI is described. A novel technique of image segmentation using radially propagating signals is discussed. Current-mode processing is used to avoid offset voltages and lead to circuit implementations which are compatible with standard CMOS processes. A system using raylike signal propagation and implemented using 3#-CMOS technology is described together with experimental results.
