A Local illumination compensation system for video encoding and decoding uses memory for storing illumination compensation parameters and does not require access to reconstructed pixels of neighboring blocks. A set of illumination compensation parameters is stored in a dedicated buffer, which is of limited size, and which is decoupled from the coding unit level storage of information. The buffer contains a set of illumination compensation parameters, which may be, for example, computed (or determined in some other manner) on the fly or determined beforehand (for example for example obtained from the video signal or from a device).

Scene aware video content encoding techniques can determine if video content is a given content type and is one of one or more given titles that include one or more given scenes. The one or more given scenes of the video content of the given type and given one of the titles can be encoded using corresponding scenes specific encoding parameter values, and the non-given scenes can be encoded using one or more general encoding parameter values. The one or more given titles can be selected based on a rate of streaming of various video content titles of the given type.

A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.

A method and wearable camera for encoding video captured by a wearable camera determines a centre of rotation for an image frame to be encoded. The centre of rotation relates to a rotation of the wearable camera at the time of capturing the video and the image frame comprises multiple groups of pixels. Furthermore, compression levels are set for the multiple groups of pixels of the image frame. The compression levels for the multiple groups of pixels of the image frame are set such that a level of compression increases with a radial distance from the centre of rotation. The image frame is encoded using the compression levels.

A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information which is commonly used in a display process of all pictures that belong to a sequence to be decoded and picture unit display control information which is individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.

Systems, methods and applications for a system for obtaining a medical interpretation for medical images include a customer portal where a customer uploads one or more medical images and accesses a marketplace for obtaining the medical interpretation, where a medical case includes one or more medical images. The system also includes an image service provider portal where a medical imaging expert accesses the medical case and provides the medical interpretation. Further, the system includes a back-end server that stores the medical case and acts as a communication conduit between the customer and the medical imaging expert.
