Finding Junctions Using the Image Gradient
(1991-12-01)
Junctions are the intersection points of three or more intensity surfaces in an image. An analysis of zero crossings and the gradient near junctions demonstrates that gradient-based edge detection schemes fragment edges ...
Computing 3-D Motion in Custom Analog and Digital VLSI
(1994-11-28)
This thesis examines a complete design framework for a real-time, autonomous system with specialized VLSI hardware for computing 3-D camera motion. In the proposed architecture, the first step is to determine point ...
