Abstract
The provided is a device for image based on FAPNN and a recognition method, comprising creating training transparent matrices corresponding to various discrete image categories in the training analog image dataset, recording each image for each image category by a Fourier convolution in one cell of the training transparent holographic matrix; generating different separate holographic cells on the 3D holographic memory matrix by simultaneously Fourier convolution of all images recorded on the training transparent holographic matrix; recording, with mechanical or optical change of the training transparent matrices, various image categories in different holographic cells of the 3D holographic memory matrix at different angles of reference beam and object beam; and receiving the analog image to be recognized, recognizing the image to be recognized and obtaining an image recognition result through values recorded in the holographic cells in the 3D holographic memory matrix.
