Abstract
For low bit rate scenarios (video conferencing, aerial surveillance), conventional video coding is unable to meet the small bit rate and high quality requirements. In contrast to that Region of Interest (ROI) coding provides an efficient compression by improving the quality of ROIs at the expense of non-ROIs. We also transmit ROI only, but reconstruct non-ROI from already transmitted content by means of global motion compensation in order to provide a high quality for the full frame. Previous ROI coding systems modified the video codec to control the coding of individual blocks. We propose a codec and ROI detector independent pre- and postprocessing framework instead. This enables the usage of off-the-shelf hard-/software and an easy adaption to the latest video coding technology. Maintaining the performance of subsequent computer vision tasks, we reduce the bit rate by 90-95 % to less than 1 Mbit/s using HEVC for full HDTV videos.
