  • Publication number: 20260065496
    Abstract: Described herein are systems and methods for generating three-dimension point clouds. Phase-shifted images of a sample are captured using a camera. Fring contrast maps are generated based on the phase-shifted images. A label map is generated based on the fringe contrast maps. In-focus pixels are extracted from the phase-shifted images to generate a wrapped in-focus phase map. A rough depth map is generated based on the label map. An artificial phase map is generated based on the rough depth map. The wrapped in-focus phase map is unwrapped and a three-dimensional point cloud is generated based on the unwrapped in-focus phase map.

  • Patent number: 11775474
    Abstract: Systems and methods that enable implementation of content aware file management labeling. Techniques disclosed enable real-time analysis of a data file so that associations between the data file and applicable file management label(s) can be automatically suggested and/or made while a user is working in the data file. A user may deploy an application on a client device to edit a data file. While the user is actively editing the data file, the application may transmit modification data to a content analysis service which analyzes the modification data to determine whether the modifications result in a file management label becoming applicable to the data file. Ultimately, the content analysis service may transmit a verdict to the client device to cause the application to display a labeling suggestion to the user and/or to automatically apply a label to the data file while it is being worked on by the user.
