  • Patent number: 12175787
    Abstract: This application discloses a three-dimensional human pose estimation method performed by a computer device. An initialization pose estimation result of a single video frame in a video frame sequence of n views is extracted based on a neural network model. Single-frame and single-view human pose estimation is performed on the initialization pose estimation result for each video frame, to obtain n single-view pose estimation sequences respectively corresponding to the n views. Single-frame and multi-view human pose estimation is performed according to single-view pose estimation results with the same timestamp in the n single-view pose estimation sequences, to obtain a multi-view pose estimation sequence. Multi-frame and multi-view human pose estimation is performed on a multi-view pose estimation result in the multi-view pose estimation sequence, to obtain a multi-view and multi-frame pose estimation result. Therefore, accuracy of human pose estimation is improved.

    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.

  • Publication number: 20230108993
    Abstract: The present disclosure provides a novel process of using nonionic surfactants in wells at, near, or below, their cloud point temperature for increased oil production from reservoir formations. Adjusting the surfactant cloud point temperature to be proximate to the reservoir temperature results in the maximum surface activity of the surfactant, increased adsorption, and better imbibition performance. The nonionic surfactants may be mixed with a solution on surface and then injected into formation brine for spontaneous brine imbibition and crude oil production from oil-wet unconventional reservoir formations. Also disclosed is a surfactant selection process that comprises initial surfactant screening, surfactant persistence tests, and spontaneous imbibition experiments to evaluate the performance of both ionic and nonionic surfactants in altering rock-oil wetting properties and improving oil recovery.
