Abstract :
The OPTIC is a high performance VLSI device designed for use in general-purpose real-time vision systems. The chip incorporates a fast proprietary (see [1]) shape- and edge-recognition algorithm, which does not require any preprocessing of the grey-level image. This makes the device especially suited to difficult machine vision problems where the image quality varies over time. The full-custom 1.5μm CMOS circuit contains 80,000 transistors and operates at an image sampling rate of 25MHz.
