  • Patent number: 11967123
    Abstract: Provided is a binarization method for CT sectional image of fiber package containing artifacts, which includes: performing brightness adjustment on the source image obtained after converting of the HSV image model by using a composite tangent function; creating a planar morphological structural element having a morphology similar to that of a target object to obtain a background image without the target object; obtaining a second intermediate image by a subtraction operation of the first intermediate image and the background image; improving an image contrast of the second intermediate image again to obtain a third intermediate image; and binarizing the third intermediate image by using a local adaptive threshold binarization algorithm and removing a background noise to obtain a final binarized image. The binarization method can improve the uneven brightness of the image under complex illumination, alleviate the artifacts, and strip similar objects from the background with similar gray scales.

  • Patent number: 11870256
    Abstract: This invention relates to a method for optimising usage 5 of electricity from the grid and energy storage comprising: forecasting a predetermined number of hours of load at a predetermined interval to determine a forecasted load profile; subtracting a peak load from the forecasted load profile by a maximum amount of electricity that can be charged into or discharged from the energy storage to determine a subtracted peak; smoothening peaks 10 within 30 minutes period that are more than the subtracted peak to obtain a final forecast result; and determining optimised battery setpoint actions based on the final forecast result and energy storage operating constraints.

  • Patent number: 8295651
    Abstract: A coherent phrase model for near-duplicate image retrieval enforces coherency across multiple descriptors for every local region. Two types of visual phrase (FCP and SCP) are employed to represent feature and spatial coherency and can be utilized without increasing the computational complexity. The FCP utilizes the information of different features by enforcing the feature coherency across multiple types of descriptors for every local region, and the SCP utilizes spatial information by enforcing the spatial coherency across the spatial neighborhoods of different sizes around every local region. Moreover, the disclosed model improves the matching accuracy by reducing the number of false matches and preserves the matching efficiency because of the sparsity of the representation.
