  • Publication number: 20200336481
    Abstract: A device authentication method, a service access control method, a device, and a non-transitory computer-readable recording medium are provided. In the device authentication method, an authentication request device issues an authentication request transaction in a distributed ledger, and an authentication response device reads the authentication request transaction in the distributed ledger and performs authentication. Thus, no third-party authentication center or coordinate device is required to participate in an authentication handshake process, thereby reducing deployment overhead of an authentication system and improving efficiency of authentication and access service control.

    Abstract: A method and an apparatus for separating a foreground image are disclosed. The method includes obtaining an input image, and color information and depth information of the input image; roughly dividing, based on the depth information of the input image, the input image to obtain an initial three-color image; reducing or expanding, based on the color information of the input image, an unknown region in the initial three-color image to obtain an optimized three-color image; and separating the foreground image from the optimized three-color image. According to the method, the initial three-color image can be optimized based on the color information of the input image, so that a more accurate three-color image can be obtained; thus the foreground image can be accurately separated from the three-color image.
