Publication number: 20240155147Abstract: 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: January 11, 2024Publication date: May 9, 2024Applicant: Microsoft Technology Licensing, LLCInventors: Xiaoyan Sun, Zhiwei Xiong, Feng Wu

Publication number: 20240070744Abstract: Embodiments described herein provide systems and methods for training a sequential recommendation model. Methods include determining a difficulty and quality (DQ) score associated with user behavior sequences from a training dataset. User behavior sequences are sampled during training based on their DQ scores. A meta-extrapolator may also be trained based on user behavior sequences sampled according to DQ score. The meta-extrapolator may be trained with high quality low difficulty sequences. The meta-extrapolator may then be used with an input of high quality high difficulty sequences to generate synthetic user behavior sequences. The synthetic user behavior sequences may be used to augment the training dataset to fine-tune the sequential recommendation model, while continuing to sample user behavior sequences based on DQ score. As the DQ score is based on current model predictions, DQ scores iteratively update during the training process.Type: ApplicationFiled: August 19, 2022Publication date: February 29, 2024Inventors: Yongjun Chen, Zhiwei Liu, Jianguo Zhang, Huan Wang, Caiming Xiong

Patent number: 9523571Abstract: An adaptive depth sensing system (ADSS) illuminates a scene with a pattern that is constructed based on an analysis of at least one prior-generated depth map. In one implementation, the pattern is a composite pattern that includes two or more component patterns associated with different depth regions in the depth map. The composite pattern may also include different illumination intensities associated with the different depth regions. By using this composite pattern, the ADSS can illuminate different objects in a scene with different component patterns and different illumination intensities, where those objects are located at different depths in the scene. This process, in turn, can reduce the occurrence of defocus blur, underexposure, and overexposure in the image information.Type: GrantFiled: October 31, 2014Date of Patent: December 20, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Zhiwei Xiong, Feng Wu, Yueyi Zhang, Pengyu Cong
