摘要： A method of capturing content on an erasable, e.g. wipeable, board or surface. The method may comprise inputting camera data for a succession of image frames, the camera being directed towards the board or surface and the image frames comprising successive images of the board/surface from the camera. The method may further comprise processing data from the image frames to remove parts of the image frames corresponding to parts of a user or user pen writing or drawing on the board or surface to determine a succession of processed images of content on the board or surface; determining a content metric for each processed image, wherein the content metric is a metric of the amount of content in the processed image; determining key frame capture times from the content metrics for the processed images; and capturing processed images at the key frame capture times.

摘要： A method of chromatically-corrected image demosaicing for a sensor with a colour filter array (CFA) such as a Bayer filter array. The demosaicing makes use of local chromatic aberration correction data to determine chromatically-corrected pixel positions for spatial interpolation. In implementations a chromatically-corrected quadratic adjustment is also applied.

摘要： A method of distributed authorization of one or more client applications to one or more connected devices. The method comprises: receiving at a connected device,from a browser executing a client application, a client token and an access request. The client token has been provided to the client application by a process comprising generating one or more client tokens, one for each of one or more client applications (a client token defines permissions for a client application and a domain hosting the client application); signing the client tokens with a private key of a client token issuer, and distributing the client tokens to the client applications; verifying a signature of the client token using a public key of the client token issuer; determining whether the client token grants the client application permission for the access request and, if permission is granted:replying to the browser with a redirect response including an access token granting permission for the client application to access the connected device and identification of the domain hosting the client application from the client token; and executing the redirect response with the browser to make the access token available to the client application for use by the client application when requesting the connected device to perform a task.

摘要： We describe a method of capturing writing or drawing on a whiteboard. The method comprises: inputting camera data for a succession of image frames, wherein the camera data is from a camera directed towards the whiteboard and the image frames comprise successive images of the whiteboard from the camera; and user filter processing data from said image frames to remove parts of said image frames corresponding to parts of a user or user pen writing or drawing on said whiteboard. The user-filter processing comprises filtering to distinguish between motion of the user/user pen parts in the image frames and writing/drawing image information in the image frames which appears or changes during said writing or drawing but which is thereafter substantially unchanging. The method outputs writing/drawing data from the user filter-processing, this defining captured writing or drawing from the whiteboard.
