Real-Time Retinal Processing for High-Resolution Optogenetic Stimulation Device

We present in this paper an image processing technique called Circular Distortion and Motion Compensation (CDMC) that can perform real-time retinal processing with geometric compensation for the ring structure arraignment in the retina for bipolar and ganglion cells. The system was running on an embedded platform of Raspberry Pi 3 and managed to achieve a respectable 12 frames per second on a $640\times 480$ resolution live video capture from a webcam. The system emulates biological processes occurring in the retina such as motion estimation and temporal filtering while compensating for the radial shift of ganglion and bipolar cells in human retina. The proposed algorithm is efficient enough to run on mobile hardware with battery powered device in real-time and it is ideal for high resolution optogenetic stimulation devices that targets the retina.
