Abstract

Real time image analysis has undergone a rapid development in the last few years, due to the increasing availability of low cost computational power. However computing power is still a limit for some high quality applications. High-resolution medical image processing, for example, are strongly demanding for both memory (∼250 MB) and computational capabilities allowing for 3D processing in affordable time. We propose the reduction of execution time of image processing exploiting the computing power of parallel arrays of Field Programmable Gate Arrays (FPGAs). We apply this idea to an algorithm that finds clusters of contiguous pixels above a certain programmable threshold and process them to ..
