  • Publication number: 20220375045
    Abstract: A method includes obtaining an input image that contains a particular representation of lens flare, and processing the input image by a machine learning model to generate a de-flared image that includes the input image with at least part of the particular representation of lens flare removed. The machine learning (ML) model may be trained by generating training images that combine respective baseline images with corresponding lens flare images. For each respective training image, a modified image may be determined by processing the respective training image by the ML model, and a loss value may be determined based on a loss function comparing the modified image to a corresponding baseline image used to generate the respective training image. Parameters of the ML model may be adjusted based on the loss value determined for each respective training image and the loss function.

  • Patent number: 10005675
    Abstract: The present invention relates to the field of nonlinear optical crystal materials and provided herein a Li4Sr(BO3)2 compound, a Li4Sr(BO3)2 nonlinear optical crystal as well as preparation method and use thereof. The Li4Sr(BO3)2 nonlinear optical crystal has a second harmonic conversion efficiency at 1064 nm of about two times that of a KH2PO4 (KDP) crystal, and an UV absorption cut-off edge less than 190 nm. Furthermore, the crystal did not disintegrate. By flux method with Li2O, Li2O—B2O and Li2O—B2O3—LiF used as flux agent, large-size and transparent Li4Sr(BO3)2 nonlinear optical crystal can grow. The Li4Sr(BO3)2 crystal had stable physicochemical properties, moderate hardness, and was easy to cut, processing, preserve and use. Therefore it can be used for preparing nonlinear optical devices and thus for developing nonlinear optical applications in the ultraviolet and deep-ultraviolet band.

  • Publication number: 20180137441
    Abstract: The present application relates to an approach for second-time resource reservation based on smart repetitive booking, which comprises: step 1, when an order is received, a first resource reservation is made in accordance with an information of the order, and an information of probability of a resource in a service area being successfully occupied; step 2, when an information of acknowledgement of a service object handover is received, a second resource reservation is made in accordance with the current time and the information of the order. When reserving a resource, the application may repetitively book the same resource based on the situation of the probability of the resource being occupied prior to each service, while making second-time reservation for the resource in the process of execution when confidence of the accuracy of reservation is high.
