摘要： Systems and methods are provided for sharing a screen from a mobile device. For example, a method includes receiving an image from a mobile device, performing recognition on the image to identify space-delimited strings, and generating a content graph for the image, the content graph having content nodes that represent at least some of the strings and the content graph having edges that represent a relative position of strings associated with the content nodes connected by the edges. The method may also include repeating the receiving, performing recognition, and generating for a plurality of images, the plurality of images belonging to a session, and generating a combined graph from the plurality of content graphs based on similarity of content nodes between content graphs, the combined graph representing text from the plurality of images in reading order.

摘要： Implementations relate to relate to rectification of distortion in an image. In some implementations, a method includes extracting edgelets from an image, each edgelet defined by a location of a pixel having an edge depicted in the image and defined by a direction of the edge. The method finds at least one vanishing point in the image based on intersections of pairs of the edges of the edgelets. Each vanishing point is selected based on a plurality of the edgelets in the image having edges approximately aligned with the vanishing point. Found vanishing points are used to transform the image to reduce image distortion.

摘要： In some implementations of edge-aware smoothing, a method includes determining a boundary map for an input image, where the boundary map associates one of multiple different labels to each pixel of the input image, and the labels indicate one or more edges in the input image. The method determines a set of input pixels of the input image eligible to influence an output pixel of an output image, the output pixel corresponding to a pixel of the input image. A blurred pixel value for the output pixel is determined, where the blurred pixel value is based on the set of input pixels and associated labels from the boundary map that correspond to the set of input pixels. The associated labels are used to reduce blurring in the output image of any of the one or more edges present in the set of input pixels.

摘要： In general, liveness detection techniques are described for facial recognition. The techniques enable potential detection and mitigation of attempts to authenticate by spoofing. An example method includes determining, by a computing device, a challenge pattern against which to match an authentication input to detect liveness, and displaying, using a display device, a graphical user interface (GUI) including an element and moving the element according to the challenge pattern within the GUI. The method further includes receiving, from an image capture device, at least a first image of a face and a second image of the face, and detecting one or more eye movements based on the first and second images of the face. The method further includes determining whether to deny authentication with respect to accessing one or more functionalities controlled by the computing device.
