Reconstruction quality as a function of time: RDAC temporal prediction avoids temporal drift, in contrast with open-loop schemes such as DAC, where quality degrades as the target frames get farther from the reference.

We address the problem of efficiently compressing video for conferencing-type applications. We build on recent approaches based on image animation, which can achieve good reconstruction quality at very low bitrate by representing face motions with a compact set of sparse keypoints. However, these methods encode video in a frame-by-frame fashion, i....

... advantage of using a closed-loop prediction scheme for temporal coding of residuals is that it avoids the temporal drifting affecting previous open-loop schemes such as DAC. This is supported by Fig. 4, where we show the temporal reconstruction quality (measured with MS-SSIM) of our framework and ...

Video compression for storage and transmission has always been a focal point for researchers in the field of image processing. Their efforts aim to reduce the data volume required for video representation while maintaining its quality. HEVC is one of the efficient standards for video compression, receiving special attention due to the increasing de...
