Image Segmentation using Neuromorphic Integrate-and-Fire Cells

This paper introduces an electronic circuit implementation of an integrate-and-fire cell. The cell generates output current pulses when the input light intensity exceeds a given threshold. A firing cell also transmits its firing pattern to neighbouring cells, thereby causing blocks of cells to fire...

Summary:This paper introduces an electronic circuit implementation of an integrate-and-fire cell. The cell generates output current pulses when the input light intensity exceeds a given threshold. A firing cell also transmits its firing pattern to neighbouring cells, thereby causing blocks of cells to fire in synchrony when their detectors receive similar input light intensities. The synchronicity and frequency of the pulses can be used to code an image into separate regions or objects. The actions of the cell are demonstrated with the simulation of a linear 8-cell array
