摘要： Video analytics systems and methods are described that typically comprise a video encoder operable to generate macroblock video analytics metadata (VAMD) from a video frame. Functional modules receive the VAMD and an encoded version of the video frame is configured to generate video analytics information related to the frame using the VAMD and the encoded video frame. The downstream decoder can use the VAMD to obtain a global motion vector related to the frame, detect and track motion of an object within the frame and monitor a line provided or found within the frame. Traversals of the line by a moving object can be detected and counted using information in the VAMD and the line may be part of a polygon that delineates an area to be monitored within the encoded frame. The VAMD can comprise macroblock level and video frame level information.

摘要： Video encoders, systems and methods are described that characterize video encoding processes using a ρ-domain deviation metric. The deviation metric represents a weighted difference between actual non-zero coefficients and the expected non-zero coefficients, the actual and expected coefficients corresponding to quantization of a macroblock in a video frame during video encoding of the frame. The deviation metric is used to adjust the video encoding process to obtain an optimized encoding bit rate for a desired video encoding quality by selecting a quantizing parameter based on a normalized value of the deviation metric. The quantizing parameter can be selected from a table indexed using the deviation metric.

摘要： A method for detecting a clear path of travel for a vehicle utilizing an image generated by a camera device located upon the vehicle includes monitoring the image, and generating a plurality of patches onto the image, wherein the patches are collectively arranged to substantially include the clear path of travel. Feature extraction is utilized to analyze the patches and includes convolving each of the patches with a feature detection filter generating a feature-based filter response, extracting features based upon the feature-based filter response, and determining each of the patches to represent the clear path of travel or to not represent the clear path of travel based upon the extracted features. The clear path of travel is determined based upon the plurality of patches, and is utilized to navigate the vehicle.

摘要： An example-based 2D to 3D image conversion method, a computer readable medium therefore, and a system are provided. The embodiments are based on an image database with depth information or with which depth information can be generated. With respect to a 2D image to be converted into 3D content, a matched background image is found from the database. In addition, graph-based segmentation and comparison techniques are employed to detect the foreground of the 2D image so that the relative depth map can be generated from the foreground and background information. Therefore, the 3D content can be provided with the 2D image plus the depth information. Thus, users can rapidly obtain the 3D content from the 2D image automatically and the rendering of the 3D content can be achieved.
