  • Publication number: 20240331403
    Abstract: An RGB-T (Thermal) multispectral pedestrian detection method based on a target aware fusion strategy, which aims to accurately determine the position of pedestrians from a pair of RGB and thermal infrared images. Given a pair of RGB and thermal infrared image to be detected, this method firstly extracts multispectral features from the RGB and thermal infrared images; then the extracted multispectral features are fused by using a target aware fusion strategy; finally, the fused features are sent to a detection head for pedestrian detection, and the pedestrian position box and confidence are output. The method can effectively fuse the deep features of multispectral images, enhance the feature expression of pedestrian areas and suppress irrelevant background noise features during the fusion process, and can realize accurate pedestrian detection.

  • Publication number: 20230041552
    Abstract: Techniques for improving a user video game experience are described. In an example, a computer system accesses videos showing separate completions of an activity by a plurality of video game players. From a definition of the activity, it is determined that the activity is a parent of sub-activities. Links to video portions of the videos are generated, wherein each video portion corresponds to a sub-activity. A score is generated for each video portion based on a relevance of each video portion to a user. The links are presented in a user interface to the user based on the score for each video portion, wherein upon selection of a first link, the user interface displays a first video to the user starting at a first video portion showing a completion of a sub-activity by a video game player.

  • Patent number: 11269914
    Abstract: Systems and methods are provided for generating reports reflecting a visualization of, e.g., a dataset on which data analysis has been performed. The data analysis performed on the dataset may be an aggregation of data analysis functionality provided by applications or tools. Dataset visualization is realized in a workspace implemented by a separate application or tool. Potential conflicts regarding updating one or more elements of the dataset are reconciled by implementing a dual operational transform system and method. A global state of the dataset may be determined by a first operational transform system and method, while a local state of the dataset may be determined by a second operational transform system and method. The local state of the dataset may be updated through operational transforms exchanged between the first and second operational transform systems that align the local state of the dataset with the global state of the dataset.
