Abstract: An encoder is configured to encode a representation of a current picture of a video stream of multiple pictures. The encoder is further configured to encode, for each of a plurality of reference pictures included in a buffer description for the current picture, a respective one-bit flag according to one of two available values for the one-bit flag. The two available values for the one-bit flag include a first value explicitly indicating to a decoder to include the reference picture in a reference picture list for decoding the current picture. The two available values for the one-bit flag further include a second value explicitly indicating to the decoder not to include the reference picture in the reference picture list for decoding the current picture. The encoder is further configured to output the representation of the current picture and the one-bit flags.

Abstract: A gain in multi-view coding is achieved as follows: the residual signal involved with coding a dependent view of the multi-view signal is predicted from a reference residual signal of the current picture of the reference view using block-granular disparity-compensated prediction, i.e. using disparity compensated prediction with a disparity defined at, and varying with, block granularity so that each block of the current picture of the dependent view has its own disparity displacement such as its own disparity vector, associated therewith. In other words, a remaining similarity between the residual signal involved with predictively coding the reference view is used in order to predict the residual signal involved with predictively coding the dependent view.

Abstract: Systems and methods are disclosed for making three-dimensional models of the inside of an ear canal using a projected pattern. A system comprises a probe adapted to be inserted into the ear canal. The probe comprises a narrow portion adapted to fit inside the ear canal and a wide portion adapted to be wider than the ear canal, which may be formed by a tapered stop. An illumination subsystem projects a pattern of light from the distal end of the probe onto a surface of the ear canal, the pattern being modulated by the three-dimensional surface of the ear canal. An imaging subsystem captures a series of individual images of the pattern of light projected onto the surface of the ear canal. A computer subsystem calculates digital three-dimensional representations from the individual images and stitches them together to generate a digital three-dimensional model of the ear canal.
