Abstract: A portable vehicle alignment system has a vertical central column with a carriage movable along its length, and a pair of camera arms pivotably attached to the carriage, each with a camera pod. The camera pods each have a camera for capturing image data of a respective vehicle-mounted target. One pod also has a calibration target disposed in a known relationship to its camera, and the other pod has a calibration camera disposed in a known relationship to its camera for capturing images of the calibration target. The camera arms pivot between an extended position where the cameras are disposed to capture image data of the vehicle targets and the calibration camera is disposed to capture images of the calibration target, and a folded position where the aligner has a width smaller than the width between the camera pods.

Abstract: A length indicator associated with an encoded representation of a slice is parsed. The length indicator is indicative of a length of an extension field present in a slice header of the encoded representation. A decoder can then determine to ignore, during decoding of the encoded representation, any value of the extension field in the slice header where these values are identified based on the length indicator. As a consequence, an extension field can be added to slice headers and still enable legacy decoders to correctly decode the encoded representations.

Abstract: In an intra-block copy video encoding method, an encoder performs a hash-based search to identify a selected set of candidate blocks for prediction of an input video block. For each of the candidate blocks in the selected set, the encoder determines a correlation between, on the one hand, luma and chroma components of the input video block and, on the other hand, luma and chroma components of the respective candidate blocks. A predictor block is selected based on the correlation and is used to encode the input video block. In different embodiments, the correlation may be the negative of the sum of absolute differences of the components, may include a Jaccard similarity measure between respective pixels, or may be based on a Hamming distance between two high precision hash values of the input video block and the candidate block.
