Advances in retinal research has recently enabled significant development in the arena of biomedical prostheses, thus enhancing the quality of therapeutic healthcare for patients suffering from retinal disorders. All vertebrates have complex vision systems, and mapping these neuroanatomical processes into a hardware platform to mimic retinal functionality is yet to be successful. A thorough understanding...
This paper implements an established signal flow platform with its foundation derived from a system of nonlinear integral equations, characterizing the functional behavior of the signal that traverses from the photoreceptor to the ganglion cell in the vision processing architecture. While an increase in computational speed over the conventional method of solving a system of nonlinear ordinary differential...
Our visual processing system is remarkably good; the retina is nothing like the CMOS image sensor, or for that matter, any of the vision processing architectures that have driven vision systems research for over three decades. Therefore, before embarking upon the complex task of architectural mapping of the retina into hardware, it is essential to gain a realistic insight into the theoretical functions...
Sensory search engines in a variety of applications, including DNA sequencing, are beginning to influence the way new search nanoarchitectures are constructed. This paper presents a novel nanoarchitecture based on a complementary resistive switch (CRS) construct for smart sensor search engines. Detailed operational principles of CRS, CRS-based memory array, and image matching applications using the...
