A novel electronic system provides fast three-dimensional model generation, social content sharing of dynamic three-dimensional models, and monetization of the dynamic three-dimensional models created by casual consumers. In one embodiment, a casual consumer utilizes a dedicated real-time 3D model reconstruction studio with multiple camera angles, and then rapidly create dynamic 3D models with novel computational methods performed in scalable graphics processing units. In another embodiment, uncalibrated multiple sources of video recording of a targeted object are provided by a plurality of commonly-available consumer video recording devices (e.g. a smart phone, a camcorder, a digital camera, etc.) located at different angles, after which the uncalibrated multiple sources of video recording are transmitted to a novel cloud computing system for real-time temporal, spatial, and photometrical calibration and 3D model reconstruction. The dynamic 3D models can be uploaded, listed, and shared among content creators and viewers in an electronic sharing platform.

A method of illumination compensation for three-dimensional or multi-view encoding and decoding. The method incorporates an illumination compensation flag only if the illumination compensation is enabled and the current coding unit is processed by one 2N2N prediction unit. The illumination compensation is applied to the current coding unit according to the illumination compensation flag. The illumination compensation flag is incorporated when the current coding unit is coded in Merge mode without checking whether a current reference picture is an inter-view reference picture.

An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm May include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.

According to an embodiment, a device includes a memory and processing circuitry. When time taken by a user to carry out first behavior is equal to or more than a first threshold, or when number of times the first behavior is repeated is equal to or more than a second threshold, the processing circuitry is configured to output first guidance to lead the user to first expected behavior that is behavior the user is expected to carry out subsequent to the first behavior. When the time taken to carry out the first behavior is less than the first threshold, or when the number of times the first behavior is repeated is less than the second threshold, the processing circuitry is configured to omit the first guidance to lead the user to the first expected behavior or outputs second guidance that is simpler than the first guidance.
