Abstract: A system and method for automatically photographing vehicles in a drive-thru structure is provided where the passage of a vehicle triggers an automated process that captures a series of vehicle images, and uploads the captured images to a web template for display and recordation.

The lighting style used to illuminate the vehicle within the structure is a sunset horizon style of lighting, where the lights are hidden below the curved wall that may be gray or white so as to use a sunset style reflection on the vehicle surface through subtractive lighting.

Abstract: The present invention is a system and method for video coding. The video coding system may involve a structural similarity-based divisive normalization approach, wherein the frame prediction residual of the current frame may be transformed to form a set of coefficients and a divisive normalization mechanism may be utilized to normalize each coefficient. The normalization factor may be designed to reflect or approximate the normalization factor in a structural similarity definition. The Lagrange parameter for RDO for divisive normalization coefficients may be determined by both the quantization step and a prior distribution function of the coefficients. The present invention may generally be utilized to improve the perceptual quality of decoded video without increasing data rate, or to reduce the data rate of compressed video stream without sacrificing the perceived quality of decoded video. The present invention has shown to significantly improve the coding efficiency of MPEG4/H.

Abstract: Errors in a double-ended motion estimation system are detected. An image space is divided into blocks, and a motion vector is derived for each block. The space is also divided into indication blocks. Each motion vector is used to identify one or more indication blocks, in which a value is modified. In an example, a backward component of the motion vector is used to project a source flag into one indication block, and a forward component of the motion vector is used to project a destination flag into another indication block. After processing each motion vector, an indication block with no flags set is indicative of pixel data that has not been tracked, and therefore indicative of a motion estimation error. Remedial action may then be taken.

Abstract: A method and apparatus for video data processing for video in YUV422 or YUV 444 formats are disclosed. In one embodiment, for a 2N×2N luma coding unit (CU) in YUV422 format, the transform process partitions residue data corresponding to the 2N×2N luma CU and the N×2N chroma CU into square luma and chroma transform units (TUs).

In another embodiment, the prediction process splits the CU into two prediction blocks. Transform process is applied on the chroma residue data corresponding to the chroma CU to form one or more chroma TUs, wherein the transform process is dependent on CU size and prediction block size, or CU size and prediction mode.

A second bitstream constructing unit constructs a bitstream of information relating to a luma intra prediction mode of a prediction block of luma signals and information relating to a chroma intra prediction mode of a prediction block of chroma signals.

Abstract: A rear vision system and a corresponding method for use with a host vehicle towing a trailer or other object. The rear vision system may include a rear facing camera, a vehicle-to-vehicle (V2V) unit, vehicle dynamic sensors, a navigation unit, a control unit, and an electronic display mirror. When the towed trailer obstructs the rear facing camera, the system and method look for unseen vehicles behind the trailer and use the V2V unit to gather information from these vehicles. This information is then used to generate a rendering that graphically depicts or represents the unseen vehicle, and the rendering is superimposed on top of the video output from the rear facing camera in the form of enhanced video output, which is then displayed on the electronic display mirror. Thus, the driver is able to “see” behind the obstructing trailer without the use of additional cameras installed on the trailer.

Abstract: A sequence of 3D VDR images and 3D SDR images are encoded using a monoscopic SDR base layer and one or more enhancement layers. A first VDR view and a first SDR view are encoded with a DVDL encoder to output first and second coded signals. A predicted 3D VDR signal is generated, which has first and second predicted VDR views. First and second VDR residuals are generated based on their respective VDR views and predicted VDR views. A DVDL encoder encodes the first and second VDR residuals to output third and fourth coded signals. A 3D VDR decoder, which has two DVDL decoders and SDR-to-VDR predictors use the four coded input signals to generate a single-view SDR, 3D SDR, single-view VDR, or 3D VDR signals. A corresponding decoder is also described, which is capable of decoding these encoded 3D VDR and SDR images.
