  • Publication number: 20200097133
    Abstract: The present disclosure discusses smart glasses. The smart glasses may capture an image and then identify one or more objects in the image. The object located at a predefined position or region in the image is informed to a user. With the method, rather than all of the objects in the image, the object at the predefined position or region is informed to a user, such that the informing efficiency of the smart glasses and user experience are improved.

  • Patent number: 10467466
    Abstract: The present application relates to layout analysis on an image. The layout analysis method comprises: obtaining coordinate information of one or more character lines in an image; generating a layout model corresponding to the image by setting character data in regions in a data structure that correspond to the coordinate information of the one or more character lines, the character data including data indicating the presence of character; scanning the generated layout model to read the character data from the layout model, and performing paragraph division on the layout model based on a relative positional relationship of the read character data in the layout model.
