End-to-end image mapping pipeline using neural networks
A recently granted patent (Publication Number: US12003746B2) outlines a computer-implemented method for image mapping using neural networks. The method involves receiving source and destination images, partitioning the process into forward and backward paths, reshaping images using neural networks, computing a joint neural network cost function, and determining operational parameters through back propagation. The method allows for converting images between different color grades and dynamic ranges, with the potential to encode image data in a video signal for reconstruction on recipient devices.
Furthermore, the patent describes the encoding of image data in a video signal along with metadata, enabling the generation of reconstructed image data of a different color grade. The method includes operational parameters for neural networks, allowing for the manipulation of color spaces and dynamic ranges. The joint neural network cost function is a key component, facilitating the conversion of images between various color grades and ensuring compatibility with different display devices. This innovative approach to image mapping and encoding opens up possibilities for enhanced visual experiences and efficient data transmission in multimedia applications.
