Latest Patents

One of Yi Song's latest patents focuses on encoding and decoding methods and apparatuses for enhancement layers. This innovative encoding method allows an encoder to obtain a reconstructed block of a base layer of a to-be-encoded picture block. It calculates the difference between corresponding pixels in the to-be-encoded picture block and the reconstructed block of the base layer to create a residual block of the enhancement layer. The method determines a transform-block partitioning manner of the residual block and performs transformation based on this manner. This application simplifies the processing procedure for the encoder and significantly improves encoding efficiency. Additionally, it enhances the compression efficiency of the residual block through an adaptive TU partitioning method.

Another notable patent involves a spherical image processing method and apparatus. This method includes obtaining a spherical image and determining its sphere center. It also identifies the user's viewpoint when viewing the spherical image, which can be any point other than the sphere center. The method determines pixel expansion and shrinkage regions based on the sphere center and the viewpoint, allowing for effective image processing operations. This includes pixel expansion processing in the expansion region and pixel shrinkage processing in the shrinkage region.
