Latest Patents
One of his latest patents is titled "Low-complexity panoramic video coding method considering distortion temporal propagation." This innovative method analyzes inter-frame reference relationships under a random access coding structure. By establishing a distortion propagation chain, it optimizes the encoding process by adjusting encoding parameters based on distortion impact factors of coding units. Additionally, it addresses oversampling issues caused by varying geometric deformations in different latitude regions during the projection of spherical images in panoramic videos. This is achieved by adjusting coding parameters according to the ratio of area changes at different latitudes, significantly enhancing coding performance.
