Abstract: A method for processing High Dynamic Range (HDR) video in order to improve the perceived visual quality of encoded content. An encoder receives an original image, wherein a contrast analysis is performed on said original image in order to highlight potential problematic areas. The original image is reduced to a decreased bit depth image in order to compute a predicted image, wherein the predicted image is then magnified to an increased bit depth image. A residual image is then computed from the original image and the increased bit depth image, and the residual image is transformed into a frequency signal. Quantized coefficients determined through the contrast analysis are then applied to the frequency signal to produce a reduced frequency signal. The encoder then inserts high-frequency components into the reduced frequency signal before encoding a compressed image from the reduced frequency image and the predicted image.

Abstract: The inventors realized that representing HDR content using LDR content and HDR residual is not unproblematic. The invention therefore proposes representing HDR content using LDR content, LDR residual and global illumination data, instead. That is, it is proposed a method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a lower dynamic range depiction of the HDR video content, the method comprising using processing means for encoding one video of the LDR video and a further LDR video extracted from the HDR video independent from the other video of the LDR video and the HDR video and predictive encoding the other video using the one video as reference, and lossless encoding global illumination data further extracted from the HDR video. This has the advantage that prediction is more stable and globally optimal predictors are more easily found.

Abstract: A mobile platform detects and tracks a three-dimensional (3D) object using occlusions of a two-dimensional (2D) surface. To detect and track the 3D object, an image of the 2D surface with the 3D object is captured and displayed and the 2D surface is detected and tracked. Occlusion of a region assigned as an area of interest on the 2D surface is detected. The shape of the 3D object is determined based on a predefined shape or by using the shape of the area of the 2D surface that is occluded along with the position of the camera with respect to the 2D to calculate the shape. Any desired action with respect to the position of the 3D object on the 2D surface may be performed, such as rendering and displaying a graphical object on or near the displayed 3D object.

Abstract: The latest High Efficiency Video Coding (HEVC) standard achieves significant compression efficiency improvement over the H.264 standard, at a much higher cost of computational complexity. A framework for software-based H.264 to HEVC transcoding on multicore processors and distributed systems is provided. By utilizing information extracted from the input H.264 bitstream, the transcoding process can be accelerated at a high ratio with modest visual quality loss. Wavefront Parallel Processing (WPP) and SIMD acceleration are also implemented to improve the trans coding efficiency on multi-core processors with SIMD instruction set extensions. Based on the HEVC HM 12.0 reference software and using standard HEVC test bitstreams, the proposed transcoder can achieve around 120× speed up over decoding and re-encoding based on ffmpeg and the HM software without significant R-D performance loss.

Abstract: A sensor synchronization system for an autonomous vehicle is described. Upon initializing a master clock on a master processing node for a sensor apparatus of the autonomous vehicle, the system determines whether an external timing signal is available. If the signal is not available, the system sets the master clock using a local timing signal from a low-power clock on the autonomous vehicle. Based on a clock cycle of the master clock, the system propagates timestamp messages to the sensors of the sensor apparatus, receives sensor data, and formats the sensor data based on the timestamp messages.

Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.
