    Time-Constant Histogram Matching for Luminance and Chrominance Compensation of Multi-View Video Sequences

    Picture Coding Symposium (PCS), Lisbon, Portugal

    2007

    Abstract anzeigen

    Significant advances have recently been made in the coding ofvideo data recorded with multiple cameras. However, lumi-nance and chrominance variations between the camera viewsmay deteriorate the performance of multi-view video codecsand renderers. In this paper, the usage of time-constant his-togram matching is proposed to compensate these differencesin a pre-filtering step. It is shown that the usage of histogrammatching prior to multi-view video coding leads to significantgains for the coding efficiency of both the luminance and thechrominance components. Histogram matching can also beuseful for image-based rendering to avoid incorrect illumina-tion and colour reproduction resulting from miscalibrations inthe recording setup. It can be shown that the algorithm is fur-ther improved by additionally using RGB colour conversion.

    Fast Video Transcoding from H.263 To H. 264/AVC

    Multimedia Tools and Applications, vol. 35, pp. 127-146

    2007

    DOI: 10.1007/s11042-007-0126-7

    Abstract anzeigen

    In the past 10 years detailed works on different video transcoders have been published. However, the new ITU-T Recommendation H.264—also adapted as ISO/IEC MPEG-4 Part 10 (AVC)—provides many new encoding options for the prediction processes that lead to difficulties for low complexity transcoding. In this work we present very fast transcoding techniques to convert H.263 bitstreams into H.264/AVC bitstreams. We will give reasoning, why the proposed pixel domain approach is advantageous in this scenario instead of using a DCT domain transcoder. Our approach results in less than 9% higher data rate at equivalent PSNR quality compared to a full-search approach. But this rate loss allows the reduction of the search complexity by a factor of over 200 for inter frames and still a reduction of over 70% for intra frames. A comparison to a fast search algorithm is given. We also provide simulation results that our algorithm works for transcoding MPEG-2 to H.264/AVC in the aimed scenario.

    Perceptually motivated spatial and temporal integration of pixel based video quality measures

    Mobile Content Quality of Experience 2007 (MobConQoE '07): Fourth International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness

    2007

    Abstract anzeigen

    In the evaluation of video quality often a full reference approach is used, thus calculating some measure of difference between the reference frames and the distorted frames. Often this measure returns one value per pixel, in the simplest case the squared difference. Conventionally, this pixel based measure is averaged over space and time. This paper introduces a psychophysically derived algorithm for this step. It uses the distribution of the cells in the fovea and the assumption that in a subjective test the part with the highest distortion is most important. Additionally, a temporal integration step is proposed which models the recency and forgiveness effect. Different video quality measures are enhanced with these two steps and their performance is evaluated using the results of a subjective test.

    Temporal Registration using 3D Phase Correlation and a Maximum Likelihood Approach in the Perceptual Evaluation of Video Quality

    Proceedings of the IEEE International Workshop on Multimedia Signal Processing

    2007

    Abstract anzeigen

    The estimation of the video quality is often performed using a full reference approach. One of the most important steps in a video quality measurement algorithm is to find the corresponding frames between the reference and the distorted video sequence. In this paper an algorithm with three steps is proposed. First, an extended version of the phase correlation is used to find candidate images with an arbitrary temporal offset, spatial scaling or spatial shift. Based on the assumption that the spatial scaling and spatial shift does not change during the sequence a set of probable parameters is selected. Finally, a maximum likelihood estimation is applied to select those temporal offsets which support the smoothest playback. A set of video sequences degraded with several distortions which are typical for multimedia scenarios are used to compare the performance to other algorithms.
