Threshold logic networks with CMOS Flash memory - Edge detection in images

What is it about?

A faster on-chip approach to edge detection and spatial filtering is proposed. The proposed circuits can be integrated along with the CMOS vision sensors to provide high speed signal processing on images. The circuit removes the need to have analog to digital converters before images can be processed, making it possible to achieve analog processing of pixel information.

Why is it important?

The proposed circuit idea can be integrated into conventional CMOS pixels for high speed filtering applications use in surveillance, object detection and tracking and feature analysis. Since the camera industry is more than $15 billion and growing, the applications of threshold logic networks offer wide range of possibility in real-time image processing.
