“…method, etc. Part III will define motion JPEG 2000 (MJP2) and will be based on Part I of JPEG 2000 [21]. MJP2 will be used in many different areas, as for example in applications where it is desired to have a single codec for both still pictures and motion sequences (which is a common feature of digital still cameras), or in applications where very high quality motion pictures are required (e.g., medical imaging and motion picture production), or in video applications in error prone environments (e.g., wireless and the Internet).…”

“…After decorrelating the data using an RGB to YCbCr transform and then applying the lifting transform, the HL, LH, and HH sub bands of the chrominance component's lifting decomposition are discarded and all other subbands retained. This has the effect of achieving a 2:1 subsampling in both the horizontal and vertical dimensions of the chrominance components [8].…”

An object-based based video codec has been designed and implemented. The codec takes a colour video sequence of arbitrary size as input and performs intra-frame object-based compression on the sequence. Video sequences are segmented using an optic flow based algorithm, before being transformed with a fast lifting transform, prior to vector quantisation and entropy encoding. A video codec quality analyser (CQA) is used to assess the subjective quality of the coded stream with respect to the uncoded one in order to provide a single quality measure that correlates with a subjective assessment of the data. Experiments using standard test sequences show that a higher compression ratio is achieved than obtainable using a similar non object-based codec, at the same quality level.

“…In terms of compression efficiency, other video compression standards outperform MJPEG2000 due to the use of motion-compensated prediction between frames. However, MJPEG2000 encodes each frame independent of others and therefore offers superior performance when considering video editing and error robustness [12]. In addition, MJPEG2000 makes use of the wavelet transform which adds the advantage of a lower computational complexity than the calculation and manipulation of motion vectors used in MPEG video compression [13].…”

To reliably transmit video over error-prone channels, the data should be both source and channel coded. When multiple channels are available for transmission, the problem extends to that of partitioning the data across these channels. The condition of transmission channels, however, varies with time. Therefore, the error protection added to the data at one instant of time may not be optimal at the next. In this paper, we propose a method for adaptively adding error correction code in a rate-distortion (RD) optimized manner using rate-compatible punctured convolutional codes to an MJPEG2000 constant rate-coded frame of video. We perform an analysis on the rate-distortion tradeoff of each of the coding units (tiles and packets) in each frame and adapt the error correction code assigned to the unit taking into account the bandwidth and error characteristics of the channels. This method is applied to both single and multiple time-varying channel environments. We compare our method with a basic protection method in which data is either not transmitted, transmitted with no protection, or transmitted with a fixed amount of protection. Simulation results show promising performance for our proposed method.
