Abstract: Aspects of the present invention are related to systems, methods and apparatus for providing a compact, yet informative, representation of meeting content.

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.

Abstract: Aspects of the present invention are related to systems, methods and apparatus for digital-marking-surface spatial management of content units and display of content units. Some aspects relate to diagrammatic gestures that invoke content-unit spatial separation on a digital marking surface. Some aspects relate to the generation and display of a transformed view of content units on a digital marking surface.

Abstract: Aspects of the present invention are related to systems and methods for determining a skew angle associated with a document image. According to a first aspect of the present invention, a rotation vector may be estimated for at least one layer in a vertical-edge buffer and a horizontal-edge buffer. According to a second aspect of the present invention, a rotation vector may be estimated directly from the vertical-edge buffer and the horizontal-edge buffer using a fixed-sized, progressively constrained histogram.

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.

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.

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.

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.
