  • Publication number: 20250078444
    Abstract: The present invention provides a method and system for multi-modal remote sensing image hybrid matching with multi-dimensional oriented self-similarity features. The method comprises: hybrid feature coarse matching is executed by rapidly extracting the image's self-similarity features using the offset mean filtering method and describing the feature points using the directional information of the self-similarity features. Through this coarse matching, an affine transformation model between multi-modal images is estimated, and an initial affine transformation is applied to the matched image. Next, the multi-dimensional oriented self-similarity feature fine matching is performed by constructing multi-dimensional oriented self-similarity template features using the multi-channel self-similarity map obtained from the hybrid feature coarse matching stage.

  • Patent number: 11954200
    Abstract: A control information processing method is provided. The method includes: simulating a controller on a first device based on a target drive file of the first device; receiving control information sent by a second device, the control information being used for controlling the first device to perform a corresponding operation; storing the control information as input information of the controller into a storage space of the target drive file; and obtaining the control information from the storage space of the target drive file in response to receiving a data read instruction that instructs to obtain the input information of the controller.

  • Publication number: 20220154338
    Abstract: Embodiments described herein generally relate to a gas assembly disposed between a mainframe door and process chamber. The gas assembly provides multi-zone gas cross-flow distribution into a processing volume. Each of the zones are independently controlled. The zones each include a single nozzle, the zones each include a plenum fluidly coupled to multiple nozzles, or a combination thereof. The nozzles, such as plenums included with nozzles, are disposed within the manifold between the first major surface and the second major surface of the manifold. An outlet of the nozzles are in fluid communication with the second major surface of the manifold, and in fluid communication with a volume of the process chamber. The multiple, independently controlled zones provide controllability of mass flow for flow sensitive chemical processes. The gas assembly include an adapter plate configured to be coupled to a vacuum mainframe robot.
