Abstract: The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.

Abstract: The techniques described herein segment objects represented in images using one or more depth maps, regardless of whether an initial depth map is of a threshold quality. To do so, the techniques contemporaneously generate, by a depth sensor, a depth map of an environment and capture, by an RGB camera, a color image of the environment. The techniques then determine whether the initial depth map is of the threshold quality. If so, the techniques use this depth map for performing segmentation on an image. If not, then the techniques generate a new depth in part by comparing an image captured by the depth sensor to the color image and performing block-matching between these images. That is, the techniques use the depth sensor and the RGB camera as stereo pair and fill in holes of the initial depth map based on the block-matching.

Abstract: A method and apparatus for capturing an image sequence using a capsule camera are disclosed. According to the present invention, a first energy-based frame time for the special images is determined based on first light energy perceived by the image sensor and a second energy-based frame time for the regular images is determined based on second light energy perceived by the image sensor. The capsule camera captures the image sequence comprising one or more sets of mixed-type images by configuring the capsule camera to cause a mixed-frame distance between the first energy-based frame time for one special image in a target set of mixed-type images and the second energy-based frame time for one regular image in the target set of mixed-type images smaller than an average frame period.

Abstract: The present disclosure provides a 3D interaction method. The 3D display device detects a distance between an operating element and a display screen and checks whether the distance is less than a maximum distance of a 3D image pointed by the operating element protruding out of the display screen. When the distance is less than the maximum protruding distance of the 3D image pointed by the operating element, the 3D display device acquires a viewing distance between a viewer and the display screen. Based on the acquired viewing distance and the distance between the operating element and the display screen, the 3D display device adjusts the parallax of the 3D image pointed by the operating element to cause an actual distance of the 3D image pointed by the operating element protruding out of the display screen equal to the distance between the operating element and the display screen.

Abstract: A method and apparatus for direct Simplified Depth Coding (dSDC) to derive prediction value directly for each segment without deriving depth prediction samples or depth prediction subsamples. The dSDC method substantially reduces the computations associated with deriving the prediction samples or subsamples and calculating the average of the prediction samples or subsamples by deriving the prediction value directly based on the reconstructed neighboring depth samples. The direct SDC can be applied to derive the two prediction values, P0 and P1 for the two segments of a depth block coded by SDC depth modelling mode 1 (DMM-1).

Abstract: Methods and devices for image and video coding using arithmetic coding. The binarization of symbols in an encoder and decoder is adaptive based on changes to the probability distribution as symbols are encoded/decoded. A binarizer may be generated based upon a probability distribution, used to binarize a symbol, and then the probability distribution is updated based on the symbol. Updates to the binarizer may be made after each symbol, after a threshold number of symbols, or once the updated probability distribution differs by more than a threshold amount from the probability distribution used in generating the current binarizer. The probability distributions may be context-specific.

Abstract: An object of the present invention is to provide a device that is capable of presenting image information that is larger than an object by irradiating light onto the object that moves on a trajectory that is not known. An object tracking section controls line of sight direction so as to be directed towards a moving object. A rendering section irradiates a light beam in a direction along the line of sight direction. In this way the rendering section can irradiate the light beam onto the surface of the object. It is possible to present information, that has been rendered in a range that is larger than the surface area of the object, to an observer, utilizing an after image of the light beam that has been irradiated on the surface of the object.

Abstract: Techniques are provided for motion estimation using hybrid video imaging based on frame-based capture and event-based capture. A methodology implementing the techniques according to an embodiment includes receiving a sequence of pixel events, generated asynchronously by an event-based video camera, and receiving a sequence of image frames generated by a frame-based video camera at a frame sampling period. The method also includes integrating a subset of the sequence of pixel events, occurring within the frame sampling period between two of the image frames, to generate a pixel motion vector representing motion of the pixel between the two image frames. The method further includes mapping the pixel motion vector to a tile of one of the image frames to generate an estimated motion vector associated with that tile.

Abstract: Provided is a video encoding/decoding technique for improving the compression efficiency by reducing the motion vector code amount. In a video decoding process, the prediction vector calculation method is switched from one to another in accordance with a difference between predetermined motion vectors among a plurality of motion vectors of a peripheral block of a block to be decoded and already decoded. The calculated prediction vector is added to a difference vector decoded from an encoded stream so as to calculate a motion vector. By using the calculated motion vector, the inter-image prediction process is executed.

Abstract: The present application relates to methods and systems for including sensor data from a sensor unit (108) as an overlay (204) in a video stream from a camera (106) monitoring a scene (200). The overlay has overlay regions (206a-f) corresponding to scene regions (202a-f), and when the sensor unit detects motion in a scene region a graphical element (208) is added to the overlay in the overlay region corresponding to that scene region. Video analytics procedures, such as object feature detection or motion or change detection may then be used to determine if detection has been made in a specific scene region by both the camera and the sensor unit.

Abstract: Systems and methods for detecting objects from a moving platform are provided. The method includes receiving, from a camera coupled to the moving platform, first and second image frames, wherein the second image frame is subsequent in time to the first image frame. Within the first image frame, a first target is defined characterizing the location of an object detected in the first image frame.

A third score associated with the first predicted target is determined. The method determines a merged target corresponding to the second target when the second score is greater than the third score and a proximity measure between the second target and the first predicted target is above a threshold.
