A sampling and weighting technique is presented. Given a 3D model that is composed out of n separated entities, a set of parameters is obtained for each entity. A weight is calculated for each entity, giving higher weight for entities corresponding to rarer parameters. Entities are assigned to components based on their corresponding parameters. Entities are sampled based on the weights or based on the components. A new 3D model is constructed from the sampled entities.

Selective 3D registration

A technique for 3D registration of three or more 3D models using parallel computing. The technique treats the pairwise 3D registration problem as an atomic sub-problem, and solves in parallel a plurality of pairwise 3D registration. The initial guess for the pairwise 3D registration is calculated based on the, possibly incomplete, information available at the moment the calculation is made. At each point the available pairwise transformations are examined based on current available information. Transformations that are identified as outliers or as inaccurate are marked for repeated pairwise 3D registration when additional information relevant for the calculation of the initial guess becomes available.

3D registration of a plurality of 3D models

Embodiments are disclosed that relate to interacting with a graphical user interface in a manner to facilitate hands-free operation. For example, one disclosed embodiment provides a method including outputting to a display device a user interface that displays graphical representations of a plurality of alignable user interface objects, each alignable user interface object representing a selectable object. The method further includes receiving depth data from an imaging device, the image data capturing an image of a face directed toward the display device. The method further comprises changing an alignment condition of a first user interface object of the plurality of alignable user interface objects to move the first user interface object into an aligned condition, and changing an alignment condition of a second user interface object to move the second user interface object out of an aligned condition based on the received image data.
