Abstract: A method of encoding a video sequence comprising Reference Picture Sets (RPSs) is provided. The method comprises arranging the RPSs in transmission order in a data structure, such as a Sequence Parameter Set (SPS), determining whether explicit RPS transmission is used for an RPS of a current picture of the video sequence, and encoding information indicating an RPS comprised in the data structure to be used for predicting the RPS of the current picture, such as delta_idx_minus1, only if explicit RPS transmission is used. By transmitting delta_idx_minus1 only if explicit RPS transmission is used, and interpreting delta_idx_minus1 to be equal to zero otherwise, a reduced bitrate is achieved. Further, a method of decoding a video sequence comprising RPSs, corresponding computer programs and computer program products, as well as corresponding encoders and decoders are provided.

Abstract: Systems and methods for transmitting video frames are described. Specifically, frame rate modification techniques such as blending and/or packing processes are used to translate high frame-rate signals into low-frame rate signals, which are transmitted over limited bandwidth transmission media to a video signal receiver. Information pertaining to the blending and/or packing processes is transferred to the video signal receiver in the form of a map that is used to reconstruct the high frame-rate signals from the low-frame rate signals. The high frame-rate signals may be used by certain types of newer equipment designed to use such signals. However, legacy equipment that cannot use the high frame-rate signals may opt to use certain embodiments described herein that are designed to be backward-compatible. When backward-compatible, the video signal receiver generates suitable low frame-rate signals as well as the high frame-rate signals, thereby accommodating both legacy as well as newer equipment.

Abstract: The computational complexity of a denoising filter is reduced while suppressing a reduction in coding efficiency. In a video encoding/decoding apparatus which uses a loop filter, a deviation degree calculating unit calculates the degree of deviation between a denoising target pixel and a surrounding pixel using a decoded image. A template shape setting unit limits a template shape so that its size is proportional to the degree of deviation relative to the maximum value of the degree of deviation in the decoded image. When noise of the target pixel is removed, weighted in accordance with the degree of similarity between a template of the target pixel and a template of each of search points in a search shape and the weighted sum of pixel values at the search points, the loop filter performs template matching using the limited template shape and removes noise of the target pixel.

Abstract: Approaches discussed herein enable a computing device to be tested to determine whether light from an emitter is bleeding through the device, which can be indicative of an assembly failure. A light blocking member can be placed over a camera in order to prevent a camera from capturing light coming from outside the device. At least one light source of the device then can be caused to emit light, and the camera can capture at least one image to determine whether any of the light is bleeding through the device and being detected by the camera. If so, the device can be determined to fail the test, and can be sent for reassembly or another remedial action. In some cases, a type of failure might be able to be determined, and information for the failure can be logged for purposes such as quality assurance and failure rate monitoring.

An image-decoding method comprises: a step of filtering an n upper reference pixel of a block to be predicted and neighboring pixels of the n upper reference pixel so as to obtain the filtered n upper reference pixel; and a step of filtering an n left reference pixel of a block to be predicted and neighboring pixels of the n left reference pixel so as to obtain the filtered n left reference pixel. According to the present invention, intra-prediction may be efficiently performed to improve image-encoding/decoding efficiency.

Abstract: Methods and systems for determining information about an object are described. In one aspect, a method includes illuminating an object with a plurality of lines of light, the lines being spaced-apart along an axis, and acquiring a sequence of images of the lines of light while rotating the object about the axis. The method further includes, for each image, determining a location of an extremum for each of the lines of light. Furthermore, the method includes establishing a reference line based on the location of the extrema for a first plurality of the lines, calculating a deviation between the extrema of a second plurality of the lines and the reference line, and determining information about the shape of the object based on the calculated deviations.

Abstract: Embodiments for reducing redundancy in video coding are disclosed. In accordance with at least one embodiment, video content is represented as a tree structure in which the nodes of the tree structure are associated with attributes of the video content. An encoder analyzes the nodes to determine whether there is redundancy associated with a last node of a divided node. In another embodiment, bidirectional prediction video coding techniques are applied to the video content. The encoder analyzes two lists of reference frames to determine whether a third mode of bidirectional prediction is redundant to a second mode of bidirectional prediction. The efficiency of video coding is improved by refraining from sending data symbols to the decoder in the event that the video coding techniques contain redundancy.

Abstract: A method of generating stereoscopic images and an autostereoscopic system are introduced. Stereoscopic images are obtained by generating, on a screen, a first image having a pattern comprising alternating columns of N left-image pixels or sub-pixels and of N right-image pixels or sub-pixels and a second image having a reversed pattern from the pattern of the first image. A parallel-strip barrier has alternating strips for blocking alternating columns of the first and second images. A tracking system provides position information related to a viewer of the stereoscopic image. A controller shifts to the left or to the right, in relation to the strips of the barrier, the image columns by a number of image pixels or sub-pixels as a function of the position of the viewer.

Abstract: A system (100) for encoding an input video frame (1005), for transmitting or storing the encoded video and for decoding the video is disclosed. The system (100) includes an encoder (1000) and a decoder (1200) interconnected through a storage or transmission medium (1100). The encoder (1000) includes a turbo encoder (1015) for forming parity bit data from the input frame (1005) into a first data source (1120), and a sampler (1020) for down-sampling the input frame (1005) followed by intraframe compression (1030) to form a second data source (1110). The decoder (1200) receives data from the second data source (1110) to form an estimate for the frame (1005). The decoder (1200) also receivers the parity bit data from the first data source (1120), and corrects errors in the estimate by applying the parity bit data to the estimate. Each bit plane is corrected in turn by a turbo decoder (1260). The decoder determines how reliably a pixel value was decoded, too.

Abstract: One aspect of the present invention provides a simple, cost-effective, efficient solution directed to the generation of the source material for the generation of still panoramic images. The precision optical alignment among all the mounted lenses, provided by the precision rectangular mounting rig, greatly reduces or eliminates stitching errors. Stitching errors often result in noticeable defects in the final image which will require human technical assistance to remedy (if the defect is of the repairable type). Accurate, error-free, source material enables virtually full automation of the panoramic imaging process; wherein the end product is high quality and quickly achieved.

As a result, panoramic imagers of the present invention can provide improved image quality and higher resolution than panoramic imagers of the prior art.

Each super frame is formed of individual lines from plural lower definition video input signals. The high definition video frames include meta data in each line identifying the video input source, line and frame. This meta data enables the super frames to be separated into their component input signals within a video processing digital signal processor.
