Publication number: 20240064327Abstract: Disclosed herein are exemplary embodiments of methods, apparatus, and systems for performing content-adaptive deblocking to improve the visual quality of video images compressed using block-based motion-predictive video coding. For instance, in certain embodiments of the disclosed technology, edge information is obtained using global orientation energy edge detection (“OEED”) techniques on an initially deblocked image. OEED detection can provide a robust partition of local directional features (“LDFs”). For a local directional feature detected in the partition, a directional deblocking filter having an orientation corresponding to the orientation of the LDF can be used. The selected filter can have a filter orientation and activation thresholds that better preserve image details while reducing blocking artifacts. In certain embodiments, for a consecutive non-LDF region, extra smoothing can be imposed to suppress the visually severe blocking artifacts.Type: ApplicationFiled: November 3, 2023Publication date: February 22, 2024Applicant: Microsoft Technology Licensing, LLCInventors: Xiaoyan Sun, Zhiwei Xiong, Feng Wu

Publication number: 20230167718Abstract: Disclosed is a method for identifying secondary reservoir formation boundaries and combined extraction of multiple asymmetric mining coalbed methane. This method fully combines the displacement transfer mechanism after multiple mining to determine its influence on a horizontal thrust of overlying strata after a first mining, and then determines evolution characteristics of pressure arches. Combining the identification of different types of pressure arches with a layout of a surface well accurately determines a secondary reservoir formation range of coalbed methane. By adopting the method of mining face overlying strata in series for combined extraction, coalbed methane from multiple mine faces is extracted by one well to greatly improve the coalbed methane extraction effect.Type: ApplicationFiled: July 22, 2022Publication date: June 1, 2023Applicants: Hancheng Zaozhuang Industrial Co., Ltd., Chongqing UniversityInventors: Xiaoyan SUN, Quanle ZOU, Qican RAN, Peimiao SANG, Jinyan LIANG, Wei PI
