Thesis Title: Computational Models of the Retina on Neuromorphic Hardware

The aim of this PhD research is to create a more refined understanding of retinal function in natural visual environments and thus create improved emulations of retinal function. Biological-inspired computational models of the retina will be developed, modelled through careful analysis of cell spike datasets recorded using multi-sensor arrays from retinas that were exposed to different visual stimuli. These computational models will be initially modelled in software (MATLAB) and then implemented on neuromorphic hardware (hardware design to mimic the biologic behaviours).

The research programme has the following objectives:

  1. Investigate more sophisticated, biologically plausible computational models of the retina, as compared to the current state of the art, and thus develop an improved understanding of how visual information is encoded in spikes from retinal ganglion cells.
  2. Analyse and model, using a high-performance cluster-computing system based on FPGAs, how the retinal response to synthetic images differs from natural scenes and how such differences are encoded.
  3. Develop specific models for selected retinal cells, for emulation in neuromorphic hardware, to solve challenging practical problems of dynamic vision in a much more biological and computationally efficient manner.
  4. Integrate such hardware emulations of specific cells to emulate overall retinal function using neuromorphic hardware (very large scale integration (VLSI) circuits that mimic neuro-biological architectures) for application in cognitive robotics.
