摘要:
Systems and methods directed to fine-grained interaction with ordinary markerless paper documents and projectors at flexible poses in 3D space. Systems and methods allow for the projection of images onto non-flat variable surfaces by utilizing depth detection techniques in order to project an image or video properly onto a variable surface.
摘要:
Methods and apparatuses for identifying an image based on Embedded Media Marker (EMM) identification. A hierarchal comparison including a first coarse comparison and a second refining comparison is used. The first coarse comparison compares an image with an EMM to images in a database at a low resolution. The results are fed to the second refining comparison, which conducts a comparison at a higher resolution than the first coarse comparison. By utilizing this hierarchical comparison approach, it is possible to identify the image with fewer false positives.
摘要:
Systems and methods provide for mixed use of physical documents and a computer, and more specifically provide for detailed interactions with fine-grained content of physical documents that are integrated with operations on a computer to provide for improved user interactions between the physical documents and the computer. The system includes a camera which processes the physical documents and detects gestures made by a user with respect to the physical documents, a projector which provides visual feedback on the physical document, and a computer with a display to coordinate the interactions of the user with the computer and the interactions of the user with the physical document. The system, which can be portable, is capable of detecting interactions with fine-grained content of the physical document and translating interactions at the physical document with the computer display, and vice versa.

Systems and methods provide for determining a location and size of a visual link to digital media on physical media such as a paper document. An authoring tool for creating a link on a paper document, such as an Embedded Media Marker (EMM), identifies and scores other EMMs and related keypoints on the document to determine similarities between a newly-created EMM and other EMMs and keypoints on the paper document. The scores are visualized for a user on a display in order to position and size the newly-created EMM in a location on the paper document that will avoid confusion with other EMMs and related content. The location and size of the newly-created EMM may be automatically adjusted based on the scoring of the keypoints and related EMMs.
