Abstract: Intra prediction is used in state-of-the-art video coding standards such as AVC. The intra prediction modes are coded into the bitstream. Luma and chroma components could potentially have different prediction modes. For chroma components, there are 5 different modes defined in AVC: vertical, horizontal, DC, diagonal down right, and “same as luma”. Statistics show that the “same as luma” mode is frequent used, but in AVC, this mode is encoded using more bits than other modes during entropy coding, therefore the coding efficiency is decreased. Accordingly, a modified binarization/codeword assignment for chroma intra mode signaling is able to be utilized for high efficiency video coding (HEVC), the next generation video coding standard.

Abstract: A method and system for warning a driver of a vehicle using a mobile device is disclosed. The method includes capturing at least one facial aspect of the driver and a path view visible ahead of the vehicle up to a predefined distance. The method further includes identifying using image analytics at least one path event demanding attention of the driver based on a path view and a field of view of the driver. The method includes detecting absence of a driver response in response to identifying the at least one path event within the field of view of the driver. The method further includes extracting driver details associated with the driver. The method includes issuing a notification to the driver based on the driver details, when the absence of the driver response is detected.

Abstract: A procedure to calibrate a depth-disparity mapping for a plenoptic imaging system. In one aspect, one or more test objects located at known field positions and known depths are presented to the plenoptic imaging system. The plenoptic imaging system captures plenoptic images of the test objects. The plenoptic images include multiple images of the test objects captured from different viewpoints. Disparities for the test objects are calculated based on the multiple images taken from the different viewpoints. Since the field positions and depths of the test objects are known, a mapping between depth and disparity as a function of field position can be determined.

Abstract: The present technique relates to an image processing device and an image processing method for realizing accurate depth image warping operations on the receiving end when depth images with reduced resolutions are transmitted. A partial resolution converting unit reduces resolutions of parallax images of auxiliary images. A partial conversion information generating unit generates partial conversion information. The parallax images having the resolutions reduced by the partial resolution converting unit and the partial conversion information generated by the partial conversion information generating unit are transmitted to a decoding device. The present technique can be applied to encoding devices that encode glasses-free 3D images, for example.

Abstract: A moving-image processing device (101) synthesizes a first moving image and a second moving image. In the first moving image, a first object is drawn, and accompanied by the anterior-surface depth of the first object. In the second moving image, a second object is drawn, and accompanied by the anterior-surface depth of the second object. A rear-surface-depth acquirer (102) acquires the rear-surface depth of the first object and the rear-surface depth of the second object. A clash determiner (103) functioning as an interference determiner refers to the anterior-surface depth and rear-surface depth of the first object to obtain an occupancy space which the first object can occupy, and refers to the anterior-surface depth and the rear-surface depth of the second object to determine whether the occupancy space and the second object drawn in certain frames of the second moving image satisfy interference conditions.

Abstract: A method of reproducing at least two digital video sequences. The method includes multiplexing a first digital video sequence with a second digital video sequence, pictures of the second digital video sequence are included in advance in a video stream and are associated with timing information such that a receiver will not decode and reproduce the pictures of the second digital video sequence. The method includes composing the at least two digital video sequences into the video stream in correspondence with a result of the multiplexing and subsequently including a sequence of dummy timing pictures into the video stream. The dummy timing pictures are inter-predicted and are coded by omitting any prediction error data.
