  • Patent number: 9547799
    Abstract: Aspects of the present invention are related to systems and methods for automatically determining the content boundaries in a digital image. A gradient field may be generated using an edge detector, and the gradient field may be thresholded, by magnitude, to retain strong edges. The resulting localized edge positions may be projected onto a first direction and a second direction to form two projection histograms. The projection histograms may be analyzed to determine the boundaries of the image content. Corners of a cropping rectangle may be computed, and the digital image may be cropped according to the content boundaries.

  • Publication number: 20150067592
    Abstract: Aspects of the present invention relate to methods and systems for interacting with a digital marking surface, in particular, to methods and systems for activating an ink tool. According to a first aspect of the present invention, an activation gesture proximate to an ink tool may activate the ink tool. According to a second aspect of the present invention, an activation gesture may initiate a determination of whether or not an ink mark proximate to the activation gesture is associated with an ink tool and may effectuate activation of the ink tool when the ink mark is associated with an ink tool. According to a third aspect of the present invention, a plurality of ink tools may be activated as a group.

  • Patent number: 8873864
    Abstract: Aspects of the present invention are related to systems and methods for automatic content-boundary detection in a digital image. According to one aspect of the present invention a received image may be preconditioned to form a normalized image from which image-content edges may be detected. Projection histograms in the direction of a known skew angle associated with the image and the normal to the skew angle may be formed to determine image-content boundaries.

  • Publication number: 20130201161
    Abstract: Aspects of the present invention are related to systems, methods and apparatus for collecting and displaying digital-marking-surface content based on semantic tags. Some aspects of the present invention relate to ink gestures that invoke content-unit tagging. Some aspects of the present invention relate to ink gestures that invoke the collection and display of like-tagged content units. Some aspects of the present invention relate to ink gestures that invoke the restoration of a viewport or digital sheet to a pre-collection state. Some aspects of the present invention relate to manipulation of content units in a collection view and the persistence of the content-unit manipulations upon restoration of a pre-collect state. Some aspects of the present invention relate to action invocation from a collection view.

  • Patent number: 8223395
    Abstract: Aspects of the present invention relate to systems and methods for refining text color in a digital image. A pixel of interest from a first plurality of pixels in a digital image may be selected, and the first plurality of pixels may be separated into a second plurality of pixels and a third plurality of pixels based on the color value of the pixel of interest. A refinement color value may be calculated based on the second plurality of pixels when the second plurality of pixels meets a quantity threshold. When the second plurality of pixels does not meet the quantity threshold, the refinement color value may be calculated based on the third plurality of pixels. The refinement color value may be assigned to the pixel of interest.

  • Patent number: 7616810
    Abstract: Aspects of the present invention comprise systems and methods for image illuminant estimation. Some aspects relate to computing an image histogram comprising data relating the frequency of image element color values to color values found under said candidate illuminants, determining match scores for the plurality of candidate illuminants, determining a minimum match score of the match scores and determining minimum match score chromaticity coordinates. Some aspects relate to fitting a surface to the match scores wherein the surface represents illuminant parameter values other than the candidate illuminants, solving for an extremum of the surface and determining chromaticity coordinates of the extremum. Some aspects relate to selecting estimated image illuminant coordinates based on the relative location of the coordinates of one of the candidate illuminants, the coordinates of the extremum and/or the minimum match score chromaticity coordinates.
