H.264/AVC is the latest video coding standard from ITU-T. It provides superior and efficient video coding at low bit rates. Flexible macroblocks ordering (FMO) is an error-resilient tool included in H.264/AVC. In this paper, a novel technique for adaptive classification of macroblocks into two slice groups using FMO method is proposed. With our adaptive macroblocks allocation map, simulation results...
Recently we proposed a block-based conditional correlation coefficient model for natural videos in the spatial-temporal domain. The conditioning is on local texture and the optimal parameters can be calculated for a specific video with a mean absolute error (MAE) usually smaller than 5%. We used this conditional correlation model and the classic results on conditional rate distortion functions to...
The loss of packets is unavoidable when compressed video data is transmitted over error prone channels. In this study, an error resilient coding scheme based on pixel lines decimation is proposed to enhance performance of error concealment for both intra and inter frames. At the encoder, an input picture is decimated by pixel lines into two similar sub-pictures and then they are merged together before...
