The long-term goal of our laboratory is the development of analog resistive network-based VLSI implementations of early and inter(cid:173) mediate vision algorithms. We demonstrate an experimental cir(cid:173) cuit for smoothing and segmenting noisy and sparse depth data using the resistive fuse and a 1-D edge-detection circuit for com(cid:173) puting zero-crossings using two resistive grids with different space(cid:173) constants. To demonstrate 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, labo(cid:173) ratory environment.
