Retiner 1.0 is a software platform running under Matlab 6.5 intended for a highly parametric simulation of retina models. It presents a friendly user interface allowing to set a variety of retina model parameters, apply the model to an image source, and watch the results of the processing performed in the form an array of spike events.
This software has been developed to allow researchers to essay and adjust retina models, predict its output, and compare it to the same output for biological records under the same stimulus. This way, the team of experts involved in the development of a cortical prosthesis for the CORTIVIS project has a tool useful for the design of the retinal stage of the implantable device.
The fact of being running on Matlab allows almost any mathematical combination of filters to be applied to the model.
The next section describes some of the features of Retiner 1.0.
