Vision-simulated imaging (VSI) is the computer generation of synthetic images to simulate a subject's vision, by incorporating the characteristics of a particular individual's entire optical system.  Using measured aberration data from a Shack-Hartmann wavefront aberrometry device, VSI modifies input images to simulate the appearance of the scene for the individual patient. Each input image can be a photograph, synthetic image created by computer, frame from a video, or standard Snellen acuity eye chart -- as long as there is accompanying depth  information. An eye chart is very revealing, since it shows what the patient would see during an eye examination, and provides an accurate picture of his or her vision.  Using wavefront aberration measurements, we determine a discrete blur function by sampling at a set of focusing distances, specified as a set of depth planes that discretize the three-dimensional space.

For each depth plane, we construct an object-space blur filter.  VSI methodology comprises several steps:  (1) creation of a set of depth images, (2) computation of blur filters, (3) stratification of the image, (4) blurring of each depth image, and (5) composition of the blurred depth images to form a single vision-simulated image.
VSI provides images and videos of simulated vision to enable a patient's eye doctor to see the specific visual anomalies of the patient. In addition to blur, VSI could reveal to the doctor the multiple images or distortions present in the patient's vision that would not otherwise be apparent from standard visual acuity measurements. VSI could educate medical students as well as patients about the particular visual effects of certain vision disorders (such as keratoconus and monocular diplopia) by enabling them to view images and videos that are generated using the optics of various eye conditions. By measuring PRK/LASIK patients pre- and post-op, VSI could provide doctors with extensive, objective, information about a patient's vision before and after surgery.  Potential candiates contemplating surgery could see simulations of their predicted vision and of various possible visual anomalies that could arise from the surgery, such as glare at night. The current protocol, where patients sign a consent form that can be difficult for a layperson to understand fully, could be supplemented by the viewing of a computer-generated video of simulated vision showing the possible visual problems that could be engendered by the surgery.

Despite phenomenal advancements in semiconductor technology over the last five decades, today’s computers still struggle with certain tasks that are easily performed by a young child. One of the first electronic implementations of a pulsed neuron was introduced in 1937 and since then research efforts have covered a wide spectrum, ranging from single-transistor models to powerful parallel processors comprised of digital signal processors. This talk will highlight some of the recent developments in the field of hardware-based neurocomputing and then present work from the University of Idaho. For the last three years, an interdisciplinary team from engineering and computer science has been working toward the development of CMOS circuits capable of mimicking the biological and signal mechanisms observed in the human nervous system. This work, funded by the National Science Foundation, is part of a larger effort within the Neuroscience program at the University of Idaho (www.grad.uidaho.edu/neuro).
