Study of a retinal layer model to generate a spike waveform for a color deficient and strabismus individual.

The physiological modeling of retinal layers to provide an insight into how the incoming image is converted into its equivalent spike train that can be decoded by the human brain is a key issue. Most of the retinal layer models concentrate mainly on image compression, edge detection and image reconstruction. A retinal layer model to generate spike waveform corresponding to the visual information is not covered much in the literature.

Physiological modeling for detecting degree of perception of a color-deficient person.

Physiological modeling of retina plays a vital role in the development of high-performance image processing methods to produce better visual perception. People with normal vision have an ability to discern different colors. The situation is different in the case of people with color blindness.

Perturbation methods to track wireless optical wave propagation in a random medium.

We consider certain problems in optical wave propagation in linear and nonlinear media in a regime of low-level atmospheric refractive index fluctuations. The perturbation theory hinges on the identification of such perturbing parameters to study its effect on the characteristics of the propagating free-space optical beam. Here, we illustrate the application of the few perturbation methods that are used to track the distorted traversing free-space optical fields.

Monte Carlo simulation of NIR diffuse reflectance in the normal and diseased human breast tissues.

The spectral reflectance measurements in tissue reveal physiological meaning. Normally, functional changes like, increase in total hemoglobin concentration, decrease in oxygen saturation, etc., are observed when there is an abnormality creeping in the normal tissue.
