Latest Patents

Jianhui Chang holds a patent for a "Method, device, system, electronic device, and storage medium for image processing." This application discloses a comprehensive image processing method that operates at the encoding end. The method involves extracting a one-dimensional feature vector from an original image block and transforming it into a multidimensional feature map. It also includes quantizing and encoding the one-dimensional feature vector to generate a first code stream, while discretely encoding the multidimensional feature map to create a second code stream. This dual-layer encoding approach allows for efficient compression and maintains information integrity during image reconstruction, even at low bit rates. As a result, it significantly improves visual effects and user experience.
