    摘要: Methods, apparatuses (100, 400, 1000), and computer program products for generating an enhanced digital image (490, 495, 1022) comprising a plurality of pixels are disclosed. Using a first digital image (420, 1020) captured from a first camera (124) and parity bits (410, 415, 1010) generated from a second digital image captured by a second camera (122, 126), a third digital image (445, 447, 1045) is constructed. The second camera (122, 126) captures the second image at a resolution different to the resolution of the first camera (124) capturing the first image (420, 1020). A disparity map (455, 457, 1055) between the first image (420, 1020) and the third image (445, 447, 1045) is determined (450, 452, 1050). One of the first image (420, 1020) and the third image (445, 447, 1045) is enhanced (470, 472, 1070) dependent upon the determined disparity map (455, 457, 1055) to generate the enhanced digital image (490, 495, 1022).

    摘要: A method of decoding a frame (1110) of video data is disclosed. The data is encoded in a format having a first field (1031) comprising a plurality of encoded key frames and a second field (1032A; 1032B) comprising data facilitating error correction of an approximation of the frame to be decoded using the first field. The method decodes (1140; 1240) at least two key frames from the first field and then determines the approximation (1157; 1257) of the frame from the decoded key frames. The method then determines (1125; 1225) a reliability (1165; 1265) for each of at least parts of the approximation, and applies (1080; 1280) the data (1032A; 1032B) facilitating error correction to the approximation (1157; 1257) of the frame, based on the determined reliabilities for the parts to thereby form the decoded frame (1135; 1235=1110).

    摘要: A method of encoding non-key frame data is disclosed. The method includes forming a bit stream from the data by arranging the bits from the data in a known order. The bit stream is interleaved to form an interleaved bit stream, and parity bits are generated for each of the bit stream and the interleaved bit stream. Bits are deleted from the generated parity bits dependant upon the bit plane of those bits, and an encoded bit stream is created from the remaining parity bits.

    摘要: A method (800) of performing distributed video encoding on an input video frame (1005), is disclosed. The method (800) forms a bit-stream from original pixel values of the input video frame (1005), such that groups of bits in the bit-stream are associated with clusters of spatial pixel positions in the input video frame (1005). The bit-stream is interleaved to reduce the clustering. The interleaved bit-stream is encoded to generate parity bits from the bit-stream according to a bitwise error correction method.

    摘要: A method of determining bit rates for use in encoding video data for joint decoding, is disclosed. An approximation of the video data is generated for later use as side information during a process of joint decoding. Bit error probabilities are determined for each bit plane and for each coefficient band of the approximation. The bit rates are determined for encoding the bit planes depending on the bit error probabilities, bit planes, and coefficient bands.

    摘要: 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. Frame reconstruction module (1290) takes advantage of this and discards unreliably decoded pixels and replaces them with predicted pixel values.

    摘要: A method and system (3000) of decoding video data using joint decoding (3100) of independently encoded sources (1010 and 3012) is disclosed. The method includes storing (1030) an initial estimate of first media data from a first source (1010). Second media data (3032) from a second source (3022) is received, with the second media data comprising parity bit data for correcting estimates derived from the first media data. The stored initial estimate is then retrieved, and the retrieved initial estimate and the received second media data are utilized to decode (3100) the media data.
