System and Method for Optical Convolutional Image Processing Using Spatial Light Modulation and Photosensitive Kernel-Embedded Film

A system for optical convolutional image processing, comprising:

• A spatial light modulator configured to emit spatially modulated light corresponding to an input image (101);
• A photosensitive film (102) positioned in front of the spatial light modulator, wherein the film is embedded with a convolutional kernel by a process comprising:
• Exposing the photosensitive film to a light pattern corresponding to a pre-trained convolutional kernel (201);
• Chemically developing the exposed photosensitive film to stabilize the imprinted kernel (204);
• Fixing the developed film (205) to ensure the stability of the kernel, thereby forming a stable, spatially modulated filter that modulates the amplitude of the light based on the spatial distribution of the kernel;
• An output plane (103) positioned to receive the modulated light, wherein the final image result formed is the convolution of the input image and the kernel;
• A camera configured to capture the final image formed on the output plane.
