  • Publication number: 20190244329
    Abstract: Photorealistic image stylization concerns transferring style of a reference photo to a content photo with the constraint that the stylized photo should remain photorealistic. Examples of styles include seasons (summer, winter, etc.), weather (sunny, rainy, foggy, etc.), lighting (daytime, nighttime, etc.). A photorealistic image stylization process includes a stylization step and a smoothing step. The stylization step transfers the style of the reference photo to the content photo. A photo style transfer neural network model receives a photorealistic content image and a photorealistic style image and generates an intermediate stylized photorealistic image that includes the content of the content image modified according to the style image. A smoothing function receives the intermediate stylized photorealistic image and pixel similarity data and generates the stylized photorealistic image, ensuring spatially consistent stylizations.

  • Patent number: 8740073
    Abstract: Methods, systems, and computer readable media for storing and redeeming an electronic certificate on a wireless smart card are disclosed. According to one aspect, the method includes storing tag data on a wireless smart card that is inductively powered when brought into the proximity of an electromagnetic field and is unpowered when outside of the proximity of the field. Tag data is received from a wireless smart card at a wireless smart device reader during an electronic transaction, wherein the card is powered by an electromagnetic field generated by the device reader. The method also includes sending, from the wireless smart device reader, transaction data, which includes at least the tag data and a vendor identifier, to a back-end server. At the wireless smart device reader, an electronic certificate is received from the server, the electronic certificate being obtained by the server using the tag data and the vendor identifier.

  • Patent number: 8165635
    Abstract: Methods, systems, and computer readable media for over the air provisioning of soft cards on devices with wireless communications capabilities are disclosed. According to one method, a soft card provisioning application is instantiated on a device with wireless communications capabilities. A card number for a soft card desired to be provisioned on the device is obtained from a user of the device. An issuer identification number retrieved from the card number is communicated to a provisioning configuration server over an air interface. A provisioning issuer server network address is obtained from the provisioning configuration server based on the issuer identification number. The provisioning information server is connected to, and card-issuer-specific challenge information is obtained therefrom. The challenges are presented to the user, and the user's responses to the challenges are received. A connection is made to the provisioning issuer server corresponding to the network address.
