Abstract: A radio transceiver included in or attached to an imaging camera is used to facilitate the automatic determination of a scale factor in a three-dimensional (3D) reconstruction. The radio transceiver transmits a radio signal from each of one or more camera positions and measures a reflection profile for the transmitted signal. The measured reflection profile is compared to a simulated reflection profile, generated from a 3D model of the subject/scene of interest, to determine an estimate of an unknown scale for the 3D model. In various embodiments, the radio transceiver may be adapted from a radio device that already exists in or on the imaging camera (e.g., a cellular radio, Bluetooth® radio, or the like) or may be added to an imaging camera.

Abstract: Viewer interaction herein triggers switching from a first view point to a second view point and thereby controls presentation of video sequences. Each video sequence comprises a sequence of images of one and the same subject and is associated with a respective view point. Images are obtained from a first video sequence associated with a first view point and are provided for presentation. Viewer input information is received that indicates a desire to present a second view point. In response, a start position within a second video sequence associated with the second view point is determined, and the obtaining of images from the first video sequence is discontinued as of the determined start position. Images are then obtained from the second video sequence associated with the second view point, starting from the determined start position, and are then provided for presentation.

Abstract: Processing of a digital image that has been recorded through an optical system is described, the image being in a raw format matrix of picture elements and comprising a plurality of subsets of picture elements, each subset corresponding to a color component. The method comprises analyzing values of picture elements of the color components in terms of spatial features, resulting in at least one calculated parameter that is representative of aberration caused by the optical system, and performing demosaicing of the digital image by, for each picture element under consideration, defining a kernel comprising picture elements that are to be considered during the demosaicing, the definition of the kernel being dependent on the at least one parameter that is representative of the aberration.
