Title: Innovations of Xiaoran Cao in Image Encoding and Decoding

Introduction

Xiaoran Cao is a prominent inventor based in Beijing, China. He has made significant contributions to the field of image processing, particularly in encoding and decoding methods. With a total of 12 patents to his name, his work has advanced the efficiency and accuracy of image data handling.

Latest Patents

Cao's latest patents focus on innovative encoding and decoding methods that utilize multiple image block division manners. One of his notable inventions is a decoding method that involves parsing a bitstream to determine if a current coding block needs partitioning. If partitioning is required, the method identifies whether to partition the block horizontally or vertically. The block is then divided into four rectangular subblocks accordingly, which are used to reconstruct the original coding block.

Additionally, he has developed an encoding method that also employs multiple image block division manners. This method determines the division manner and direction of an image block, allowing for the sequential arrangement of image subblocks. It assesses whether these subblocks require further subdivision and, if not, predicts the encoding object in the frame based on the subblocks to obtain residual data. This process includes transformation, quantization, and entropy encoding, ultimately writing the division manner, direction, and coded residual data into a bitstream. This innovative approach enhances prediction accuracy, especially when dealing with minor pixel value changes.
