A method performed by a display system is provided. The method includes projecting a first infrared pattern from a first projection plane of a first projector into a scene, capturing the first infrared pattern from the scene in a capture plane of at least one image capture device, and determining a first correspondence mapping between the first projector and the image capture device from at least the first infrared pattern in the first projection plane and the first infrared pattern in the capture plane.

Various embodiments of the present invention include a grazing routine that selects data objects from a data-object library or database based on selection-criterion values associated with each data object and provides the data objects to a presentation routine that uses the data objects to continuously update a data-object presentation. User input directs subsequent data-object selection by the grazing routine to allow users to intuitively navigate and search a large data-object library in order to locate one or a set of particular data objects. Users can input selection commands to specific presented data-objects in order to focus subsequent data-object selection and data-object presentation to increasingly smaller sub-populations of data objects. In the absence of user input, the sub-population of data objects from which data objects are selected for presentation may be increased.

A concurrent presentation of video segments of a video file enables rapid comprehension of the video file. A video file is segmented into video segments and a condensed representation of the video file is generated. The condensed representation corresponds to a concurrent presentation of the video segments in respective windows in a display area over repeating cycles of a loop period. The concurrent presentation may be processed to concurrently present video segments corresponding to contiguous sections of the video file in respective windows in a display area over repeating cycles of a loop period.

In a method for determining a temporal occlusion cost for a video crop, video image saliency data for a video is received. A video crop is received for a presenting an edited version of the video within a viewing region. The video image saliency data is used to determine a temporal occlusion cost for the video crop.

In a method of evaluating compositional quality of a layout orientation of an image, image saliency data is received for an image to be presented in a viewing region. A layout orientation for presenting the image in the viewing region is received. A composition template embodying an image composition rule is received. The image saliency data and the composition template are utilized to determine a weighted occlusion cost for the layout orientation. The weighted occlusion cost is utilized to determine a composition score indicating quality of the layout orientation with respect to the image composition rule.

In a computer implemented method of generating a collage of images, image saliency data is received for a plurality of images that are to be collaged within a templated viewing region. The templated viewing region is generated by scaling a template relative to the plurality of images that are to be collaged. An initial collage layout is generated within the templated viewing region from the plurality of images. The initial collage layout is optimized, where the optimizing comprises iteratively adjusting the initial collage layout by selecting a minimized layout occlusion cost.

In a method of evaluating an image for a dominant line, warped mesh information regarding saliency of the image is received. Displacements of components of the warped mesh information are determined relative to corresponding components in un-warped mesh information. Statistical representations of the displacements are utilized to evaluate the image for a dominant line.

In a method for generating a dimensionally tractable set of image layout constraints, a selected constraint is applied to limit a dimension of a highly dimensional solution space. Through random selection one or more unconstrained dimensions of the highly dimensional solution space are identified which, when constrained, will further limit the highly dimensional solution space to a dimensionally tractable solution space. The tractability of the dimensionally tractable solution space is associated with a capability of a computational resource.

Various method and system embodiments of the present invention are directed to computational estimation of a tempo for a digitally encoded musical selection. In certain embodiments of the present invention, described below, a short portion of a musical selection is analyzed to determine the tempo of the musical selection. The digitally encoded musical selection sample is computationally transformed to produce a power spectrum corresponding to the sample, in turn transformed to produce a two-dimensional strength-of-onset matrix. The two-dimensional strength-of-onset matrix is then transformed into a set of strength-of-onset/time functions for each of a corresponding set of frequency bands. The strength-of-onset/time functions are then analyzed to find a most reliable onset interval that is transformed into an estimated tempo returned by the analysis.

In a computer implemented method of creating a collage of images, a first image is seeded into a viewing region to start the collage. A plurality of trial layout arrangements are provided with an additional image added to the collage. An occlusion cost is generated for a trial layout arrangement. The occlusion cost represents image saliency occluded and viewing region saliency occluded by the trial arrangement. An image is added to the collage, by updating the collage to reflect one of the trial layout arrangements for which the occlusion cost has been generated.
