Abstract: In illustrative implementations of this invention, multi-path analysis of transient illumination is used to reconstruct scene geometry, even of objects that are occluded from the camera. An ultrafast camera system is used. It comprises a photo-sensor (e.g., accurate in the picosecond range), a pulsed illumination source (e.g. a femtosecond laser) and a processor. The camera emits a very brief light pulse that strikes a surface and bounces. Depending on the path taken, part of the light may return to the camera after one, two, three or more bounces. The photo-sensor captures the returning light bounces in a three-dimensional time image I(x,y,t) for each pixel. The camera takes different angular samples from the same viewpoint, recording a five-dimensional STIR (Space Time Impulse Response). A processor analyzes onset information in the STIR to estimate pairwise distances between patches in the scene, and then employs isometric embedding to estimate patch coordinates.

Abstract: Moving pictures, as may be exemplified by television programming, are viewed stereoscopically. The system preferably comprises a visual display screen upon which may be displayed a left-to-right reversed visual display. A reflecting surface is positioned opposite the visual display screen for reflecting imagery from the visual display screen toward the viewer. The reflected imagery provides a reflected left-to-right correct visual display. The visual display screen is spaced from the reflecting surface such that the viewer's perception of the visual display screen causes the viewer to focus on a point behind the reflecting surface thereby requiring the viewer to perceive laterally offset reflections of the visual display screen at the reflecting surface.

Abstract: In one aspect of this disclosure, techniques are described for selecting among default weighted prediction, implicit weighted prediction, and explicit weighted prediction. In this context, techniques are also described for adding offset to prediction data, e.g., using the format of explicit weighted prediction to allow for offsets to predictive data that is otherwise determined by implicit or default weighted prediction.

Abstract: A method of motion vector prediction for use in differential motion vector coding within a block motion-compensation-based video coder. The video coder employs a generalized multiple reference picture buffer which may contain multiple reference pictures in both the forward and backward temporal direction from the current picture. For the purpose of coding selections of reference pictures within the buffer, the pictures are organized into two, potentially overlapping, lists of reference pictures. The prediction of a motion vector that selects a reference picture using a given reference picture list is not dependent upon any motion vectors that select their reference pictures using the other reference picture list. The values of spatially neighboring motion vectors that use the same list of reference pictures as the motion vector being predicted are used for prediction, regardless of the relative temporal direction of the current and neighboring motion vectors.

Abstract: A method and a device for describing and capturing video objects are provided in the embodiments of the present application, including: capturing video images to generate video sequences, generating a video object tracking sequence (OTS) according to the video sequences, and generating video object descriptors (ODs) according to the video OTS and video sequences. Therefore, in a generated video object tracking sequence (OTS), the video object region tracking number (TID) is used to capture and track video objects. This makes it unnecessary to create a video object descriptor (OD) for each video object on a frame-by-frame basis. Therefore, the quantity of video ODs is reduced, thereby suiting the application requirement for the intelligent video interaction and accelerating the search of the video materials.

In addition, the method includes segmenting macroblocks of a destination video frame in a raster order into groups based on reference parameters thereof using the driver, where the reference parameters define compensation needs of macroblocks of the destination frame. The method also includes constructing an indexed array of linked-lists using the driver, with each linked-list representing macroblocks of a group having the same reference parameters. The hardware accelerator may be programmed to accelerate motion compensation by reconstructing macroblocks of the destination frame group-wise in the indexed order of the array of linked-lists.
