  • CALCULATION SYSTEMS FOR PREDICTING PROPPANT EMBEDDING DEPTH BASED ON SHALE SOFTENING EFFECT
    Publication number: 20240133281
    Abstract: A calculation system for predicting a proppant embedding depth based on a shale softening effect is provided, including a sampling test terminal, a scheduling module, a monitoring module, and a calculation module, wherein the scheduling module, the monitoring module, and the calculation module are connected in communication, and the monitoring module is connected to an external operating system through a wireless network, wherein the external operating system is configured to perform a hydraulic fracturing operation and receive a first control signal and/or a second control signal from the monitoring module. The sampling test terminal is configured to test the samples and obtain test data. The scheduling module is configured to determine a target construction parameter.

  • Apparatus and method for optimized image stitching based on optical flow
    Patent number: 11748952
    Abstract: An apparatus and method for efficient image optimized image stitching. For example, one embodiment of an apparatus comprises: feature search area identification circuitry/logic to narrow down a feature search area based on possible overlap between two image frames; feature detection circuitry/logic to identify a plurality of feature points in a first image frame of the two image frames; feature matching circuitry/logic to map one or more of the plurality of feature points from the first image frame to corresponding feature points in the right image frame; image frame stitching and blending circuitry/logic to stitch the first image frame and second image frame based on the mapping of the feature points between the two image frames and to blend a portion of the first image frame with a portion of the second image frame.

  • Tone-mapping high dynamic range images
    Patent number: 10943336
    Abstract: A tone-mapping technique based on bidirectional logarithm stretch enhances the luminance contrast of not only the dark areas but also the bright areas. In other words, the algorithm not only maps the dark pixels brighter but also map the bright pixels darker.
