Abstract EN
This work relates to the regions-of-interest (ROI) coding that is a desirable feature in future applications based on the scalable video coding, which is an extension of the H.264/MPEG-4 AVC standard.
Due to the dramatic technological progress, there is a plurality of heterogeneous devices, which can be used for viewing a variety of video content.
Devices such as smartphones and tablets are mostly resource-limited devices, which make it difficult to display high-quality content.
Usually, the displayed video content contains one or more ROI(s), which should be adaptively selected from the preencoded scalable video bitstream.
Thus, an efficient scalable ROI video coding scheme is proposed in this work, thereby enabling the extraction of the desired regions-of-interest and the adaptive setting of the desirable ROI location, size, and resolution.
In addition, an adaptive bit-rate control is provided for the region-of-interest scalable video coding.
The performance of the presented techniques is demonstrated and compared with the joint scalable video model reference software (JSVM 9.19), thereby showing significant bit-rate savings as a tradeoff for the relatively low PSNR degradation.
