Digital video processing requires significant hardware resources to achieve acceptable performance. Digital video processing based on dynamic partial reconfiguration (DPR) allows the designers to control resources based on energy, performance, and accuracy considerations. In this paper, we present a dynamically reconfigurable implementation of a 2D FIR(More)
—A Computer Aided Diagnosis system based on mul-tiscale amplitude-modulation frequency-modulation (AM-FM) methods has been recently developed for discriminating between normal and pathological retinal images. The original Matlab implementation of this system required large amounts of computational time and memory resources that would not permit real-time(More)
Diabetes afflicts an estimated 171 million people worldwide. Diabetic patients are at risk of a wide range of complications including peripheral neuropathy (or diabetic foot). The condition if left untreated will lead to ulcers and eventually lower extremity amputation. Current existing diagnostic techniques for peripheral neuropathy are mostly qualitative(More)
The discrete periodic radon transform (DPRT) has extensively been used in applications that involve image reconstructions from projections. Beyond classic applications, the DPRT can also be used to compute fast convolutions that avoids the use of floating-point arithmetic associated with the use of the fast Fourier transform. Unfortunately, the use of the(More)
