Image edge detecting by using the bacteriorhodopsin-based artificial ganglion cell receptive field
The differential response of the bacteriorhodopsin film was employed to fabricate a 2D ON-center ganglion cell receptive field. The receptive field was characterized as a zero-cross filtering, which was successfully used to detect the edge of an image.
