Implementation and Validation of a Looming Object Detector Model Derived from Mammalian Retinal Circuit



The model of a recently identified mammalian retina circuit, responsible for identifying looming or approaching objects, is implemented on mixed-signal focal-plane sensor-processor array. The free parameters of the implementation are characterized; their effects to the model are analyzed. The implemented model is calibrated with real stimuli with known kinetic and geometrical properties. As the calibration shows, the identified retina channel is responsible for last minute detection of approaching objects.

The explanation of the neurobiological system level background of the model by Botond Roska is greatly admired.
