With a total of 2 patents to his name, Yuan's work is recognized for its innovative approaches to encoding and decoding techniques.

Latest Patents

Yuan's latest patents include a coefficient coding/decoding method, an encoder, a decoder, and a computer storage medium. The first patent outlines a method that involves parsing a bitstream using adaptive binary arithmetic coding. This method utilizes a first context model based on quantization coefficient positions to decode values of non-zero identifications. If the value is identified as a first value, the method continues by parsing the bitstream with a second context model to obtain values of preset identifications. The process further includes determining a target order for exponential Golomb coding and utilizing an exponential Golomb decoding algorithm to reconstruct quantization coefficient absolute values.

The second patent focuses on a coefficient encoding method and a coefficient decoding method, along with corresponding devices and a storage medium. In this method, the coefficient value is determined based on syntax elements obtained through decoding. These elements include flags for non-zero identification, absolute values, modulo results, residual values, and sign indicators. The absolute value of the coefficient is calculated from the sum of numerical values preset for the coded flags, along with the product of the encoded residual value flag.
