One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...

Pixel size scaling is a development trend in CMOS Image Sensor (CIS) to achieve high array resolution and chip miniaturization for lower cost and smaller device form factors. The latter is especially important for mobile smart handset market. Technology challenges arise due to the scaling for maintaining optical and electrical pixel performance. The limited pixel size constraints the in-pixel t...

The last few years have seen the advent of Smart Cameras, surveillance-camera sized devices with onboard programmable logic. Usually, Digital Signal Processors (DSPs) or general-purpose (GP) microprocessors are used, but obviously the specific field of image processing allows for many architectural optimizations, such as the use of single-instruction multiple-data (SIMD) processors for filterin...

Smart cameras are among the emerging new fields of electronics. The points of interest are in the application areas, software and IC development. In order to reduce cost, it is worthwhile to invest in a single architecture that can be scaled for the various application areas in performance (and resulting power consumption). In this paper, we show that the combination of an SIMD (singleinstructi...
