Real-Time Computer Vision and Robotics Using Analog VLSI Circuits

The long-term goal of our laboratory is the development of analog resistive network-based VLSI implementations of early and intermediate visionalgorithms. We demonstrate an experimental circuit for smoothing and segmenting noisy and sparse depth data using the resistive fuse and a 1-D edge-detection circuit for computing zero-crossingsusing two resistive grids with different spaceconstants. Todemonstrate the robustness of our algorithms and of the fabricated analog CMOS VLSI chips, we are mounting these circuits onto small mobile vehicles operating in a real-time, laboratory environment.
