Abstract
Low bit rate transmission of HD video captured from UAVs is highly interesting. Assuming a planar surface, areas contained in the current frame but not in the previous frames (New Area) can be reconstructed using Global Motion Compensation (GMC). Aiming at stereo reconstruction from monocular video by using motion parallax, a second view of each image pixel has to be additionally transmitted. Whereas the bit rate can be considerably reduced compared to standardized video coding to about 1-2 Mbit/s, artifacts at the boundaries between new areas and GMC reconstructed areas may occur, e. g. due to illumination changes. We propose a gradient correction of the new areas to adjust the luminance. Furthermore, we utilize a general ROI coding framework to become independent of any encoder modifications. We achieve a subjectively higher video quality while saving 2% BD-rate compared to a specifically adapted encoder by exploiting latest encoder optimizations of x265.
