Abstract: Disclosed is a method and apparatus for selecting a part of SLAM map information of a first device for transmission to a second device in a collaborative SLAM environment. In one embodiment, the functions implemented include: determining whether a 3D registration transformation between a map of the first device and a map of the second device is available; and transmitting a part of map information of the first device to the second device according to one of a first strategy or a second strategy based on whether or not a 3D registration transformation between the map of the first device and the map of the second device is available.

Abstract: Disclosed is a computing device that can perform automatic image rectification for a visual search. A method implemented at a computing device includes receiving one or more images from an image capture device, storing the one or more images with the computing device, building a three dimensional (3D) geometric model for one or more potential objects of interest within an environment based on at least one image of the one or more images, and automatically creating at least one rectified image having at least one potential object of interest for a visual search.

Abstract: Systems, apparatus and methods to create a database by a device (such as a server) and to use the database by a mobile device for detecting a planar target are presented. The database allows recognition of a planar target by a mobile device from steeper angles with minimum impact on runtime. The database is created from at least one warped view of the planar target. For example, a database may contain keypoints and descriptors from a non-warped view and also from one or more warped views. The database may be pruned by removing keypoints and corresponding descriptors of one image (e.g., a warped image) overlapping with similar or identical keypoints and descriptors of another image (e.g., a non-warped image).

Abstract: Systems, methods, and devices are described for constructing a digital representation of a physical scene by obtaining information about the physical scene. Based on the information, an initial portion of a planar surface within the physical scene may be identified. In one aspect of the disclosure, constructing a digital representation of a physical scene may include obtaining information about the physical scene, identifying a planar surface within the physical scene, selecting a physical object within the physical scene, placed above the planar surface, detecting properties associated with the physical object, generating a three-dimensional (3D) reconstructed object using the properties associated with the physical object, and representing the planar surface as an augmented reality (AR) plane in an augmented reality environment, wherein the AR plane in the AR environment is capable of supporting 3D reconstructed objects on top of it.

Abstract: Various methods, apparatuses and/or articles of manufacture are provided which may be implemented for use by an electronic device to track objects across two or more digital images. For example, an electronic device may generate a plurality of warped patches corresponding to a reference patch of a reference image, and combine two or more warped patches to form a blurred warped patch corresponding to the reference patch with a motion blur effect applied to a digital representation corresponding to a keypoint of an object to be tracked.
