IMAGE RECOGNITION SYSTEM USING A PROGRAMMABLE PHOTONIC NEURAL NETWORK

A system uses arrays of spatial light modulators (SLMs) connected to a processor and an image capture device. An image is input into a first array of SLMs. The processor determines if the output of the first array matches an image stored within a database. If a match is found, the processor outputs a stored image to an image processing system. If a match is not found the processor directs the output from the first array into an input of an array of SLMs adjacent to the first array. The determination step is iteratively performed for the remaining arrays of SLMs until a match is found or no arrays remain. If no arrays remain, the processor selects a stored image from the database and obtains user feedback from a user input system. The feedback is then stored in the database and associated with the n−1 array of SLMs.
