Publication number: 20220207821Abstract: An image rendering method and a related apparatus, terminal and storage medium that: obtains a low-resolution first shadow map and a high-resolution second shadow map of a target virtual object, determines a first texel range of each texel and a central point in the first shadow map, performs scaling processing, based on the central point, on the first texel range by using a scaling coefficient to obtain a second texel range, and performs shadow rendering on the target virtual object according to the second texel range. A shadow map-based image rendering process is implemented, and since a calculation amount of determining a map position according to a low-resolution map is relatively small, image rendering efficiency is improved. Additionally, rendering of a high-resolution shadow map is completed, generation of edge aliasing is avoided, and an image rendering effect is improved.Type: ApplicationFiled: March 17, 2022Publication date: June 30, 2022Applicant: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Huabing XU, Shun Cao, Nan Wei, Xiaochun Cui, Congbing Li, Rongxin Zhou, Wenyan Li

Publication number: 20220028373Abstract: Methods for automatically evaluating ASR outputs and providing annotations, including corrections, on the transcriptions—in order to improve recognition—may be based on an analysis of sessions of user voice queries, utilizing time-ordered ASR transcriptions of user voice queries (i.e., user utterances). This utterance-based approach may involve extracting both session-level and query-level characteristics from a voice query sessions and identifying patterns of query reformulation in order to detect erroneous transcriptions and automatically determine an appropriate correction. Alternative, or in addition, ASR outputs may be evaluated based on user behavior. The outcomes may be classified as positive or negative. An ASR transcription may be labeled using the description of the outcome. The labeled transcription may be used as training data to train a model to output improved transcriptions of voice queries.Type: ApplicationFiled: July 22, 2021Publication date: January 27, 2022Inventors: Wenyan Li, Ferhan Ture, Jose Casillas, George Thomas Des Jardins
