The CNS Vision Lab conducts psychophysical and computational modeling studies of many aspects of visual perception. Some of our research projects are:| CONFIGR: CONtour FIgure and GRound | |
|---|---|
 |
CONFIGR is a model that performs long-range contour completion on large-scale images, using a mechanism that fills-in both figure and ground via complementary process. |
| Color Perception | |
 |
What determines the color of objects that you see? |
| Heading Perception: Where am I going? | |
 |
A model of motion processing neurons demonstrates how primates, including humans, determine their direction of travel from visual input. The model links neurophysiology with psychophysics and technology. |
| Spatiotemporal frequency-dependent speed perception | |
 |
The perception of velocity is influenced by many factors besides the physical speed and direction of moving objects. In particular this project investigates the influence of temporal sampling on speed perception. |
| Spiking Bipole Cells | |
 |
A model of cortical Layer 2/3 pyramidal cells shows how grouping can be done at the level of small cell populations. Model cells consist of two compartments governed by Hodgkin-Huxley equations and are connected via slow synapses. |
