This two-volume complaints constitutes the refereed papers of the seventeenth foreign Multimedia Modeling convention, MMM 2011, held in Taipei, Taiwan, in January 2011. The fifty one revised normal papers, 25 unique consultation papers, 21 poster consultation papers, and three demo consultation papers, have been conscientiously reviewed and chosen from 450 submissions. The papers are prepared in topical sections on audio, photo video processing, coding and compression; media content material shopping and retrieval; multi-camera, multi-view, and 3D structures; multimedia indexing and mining; multimedia content material research; multimedia sign processing and communications; and multimedia purposes. The distinct consultation papers care for content material research for human-centered multimedia functions; huge scale wealthy media information administration; multimedia knowing for buyer electronics; snapshot item attractiveness and compression; and interactive picture and video search.

Example text

2 software platform provided by JVT. 26GHz working frequency. 0, and all of the frames are encoded by using I-frame coding, and then each video sequence contains 300 frames, and the high complexity RDO is enabled. To compare the rate distortion and the quality performance of the proposed algorithm with the others, the PSNR and the bitrate are measured by using Bjontegaard’s method [9] for the quantization parameters (QPs) assigned at 28, 32, 36, and 40, respectively. Tables 1 and 2 show the BMA method in QCIF and CIF sequences respectively, where Δ PSNR denotes the average difference of the peak signal-to-noise ratio, Δ BR indicates the average bit-rate increase, and Δ TIME indicates the average time saving in coding process.

At the second step, we use both chroma components of U and V to compute the primary directional mode and the non-directional DC mode, and find the final primary mode, and the procedure. Efficient Mode Selection with BMA Based Pre-processing Algorithms 17 For both luma-16x16 and chroma-8x8 mode selection processes, when the primary mode is decided, we can finally send the primary mode to the cost generation and mode decision unit, which means that the primary mode is the best mode. For example, when the vertical mode has the smallest SAD, it is selected and sent to the mode decision.

The DC coefficient, and motion vectors. Based on these DC images, similarity metrics defined for color features in the pixel domain can be modified to operate in the compressed domain. On the other hand, the distribution of the different macroblock types and motion information [4,11] can also be used as features to detect shot boundaries. When an abrupt transition occurs between two successive P pictures, it is expected that a significant amount of macroblocks in the second frame is intra coded since these macroblocks cannot be predicted well from prior reference frames.
