Logo insertion transcoding for H.264/AVC compressed video
2009
2009 16th IEEE International Conference on Image Processing (ICIP)
Preserved Fulltext
In this paper, we propose a novel and efficient logo-insertion scheme for H.264/AVC compressed videos. ...
H.264/AVC quickly gains ground in many aspects of video applications, due to its superior coding performance. ...
Furthermore, the deblocking filter used in H.264/AVC is another way of creating video-content dependencies. ...

In this work, we develop a deep learning architecture capable of restoring detail to compressed videos which leverages the underlying structure and motion information embedded in the video bitstream. ...
We show that this improves restoration accuracy compared to prior compression correction methods and is competitive when compared with recent deep-learning-based video compression methods on rate-distortion ...
Although H.265 is an exciting modern codec it is underutilized with H.264 (AVC) covering many more videos [1] , and the degradations H.265 causes are less noticeable. ...
