  • Publication number: 20220207821
    Abstract: 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.

  • Publication number: 20220028373
    Abstract: 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.

  • Patent number: 10767058
    Abstract: Corrosion inhibitor materials are provided that release active corrosion inhibitor compounds when they are most needed—in response to changes in conditions, including acid or basic pH, that cause corrosion or occur at the early stages of corrosion. The materials comprise particles that can be dispersed in paints and coatings for metals. The particles in some cases include ionic water-soluble anti-corrosion agents complexed to oppositely charged surfactants and entrapped in silica oxide or metal oxide gels.

  • Patent number: 9233394
    Abstract: Hydrophobic-core microcapsules and methods of their formation are provided. A hydrophobic-core microcapsule may include a shell that encapsulates a hydrophobic substance with a core substance, such as dye, corrosion indicator, corrosion inhibitor, and/or healing agent, dissolved or dispersed therein. The hydrophobic-core microcapsules may be formed from an emulsion having hydrophobic-phase droplets, e.g., containing the core substance and shell-forming compound, dispersed in a hydrophilic phase. The shells of the microcapsules may be capable of being broken down in response to being contacted by an alkali, e.g., produced during corrosion, contacting the shell.
