A Processing Platform for Optoelectronic/Optogenetic Retinal Prosthesis Abstract The field of retinal prosthesis has been steadily devel- oping over the last two decades. Despite the many obstacles, clinical trials for electronic approaches are in progress and already demon- strating some success. Optogenetic/optoelectronic retinal prosthe- sis may prove to have even greater capabilities. Although resolu- tions are now moving beyond recognition of simple shapes, it will nevertheless be poor compared to normal vision. If we define the aim to be to return mobility and natural scene recognition to the patient, it is important to maximize the useful visual information we attempt to transfer. In this paper, we highlight a method to simplify the scene, perform spatial image compression, and then apply spike coding. We then show the potential for translation on standard consumer processors. The algorithms are applicable to all forms of visual prosthesis, but we particularly focus on optogenetic approaches.
