  • Publication number: 20190278977
    Abstract: This specification describes techniques for verifying authenticity of an image. One example method includes identifying a baseline image depicting a baseline background; identifying a comparison image depicting a card; identifying a comparison background in the comparison image, wherein the comparison background is an area of the comparison image other than an area occupied by the card; determining a probability that the baseline background matches the comparison background; determining that the probability satisfies a verification threshold; and in response to determining that the probability satisfies a verification threshold, determining that the comparison image was acquired by capturing an image of a physical card corresponding to the card depicted in the comparison image.

  • Patent number: 9237756
    Abstract: A method for preparing and conditioning granular burdock through combined uniform drying by using radio frequency (RF) pretreatment and microwave pulse spouting is provided. The process of the present disclosure includes performing pretreatment on fresh burdock, protecting color, pre-drying by RF, drying through microwave pulse spouting, and packaging. The color and luster of a product are greatly improved after color protection, the RF pre-drying treatment may be performed for 20 minutes, and hot air drying treatments for removing moisture on the surface may be performed for 60 minutes. The method has a short drying time and high efficiency. The sectional microwave pulse spouting treatment needs 60 minutes totally, while the complete hot air drying treatment needs 400 minutes. Therefore the drying time of the method is greatly shortened, and the drying is uniform, and a sample after microwave pulse spouting drying has strong fragrance.
