Studies on spatial scalable frameworks for motion aligned 3D wavelet video coding

Ruiqin Xiong, Jizheng Xu, Feng Wu, Shipeng Li
2005 Visual Communications and Image Processing 2005  
The frameworks with multiple image-domain motion aligned temporal filtering at various spatial resolutions, named as multi-T+2D, are mainly investigated.  ...  To remove the redundancy produced in the multi-resolution temporal filtering while retaining the advantage of spatial-domain motion compensation, a novel non-redundant multi-T+2D scheme is proposed.  ...  The multiresolution property of wavelet representation makes it a nature solution for spatial-temporal resolution scalability.  ...

Video-to-Video Translation with Global Temporal Consistency

Xingxing Wei, Jun Zhu, Sitong Feng, Hang Su
2018 2018 ACM Multimedia Conference on Multimedia Conference - MM '18  
To overcome this issue, a usual method is to incorporate the temporal loss between adjacent frames in the optimization, which is a kind of local frame-wise temporal consistency.  ...  In this paper, we propose an unified video-to-video translation framework to accomplish different tasks, like video super-resolution, video colourization, and video segmentation, etc.  ...  Noted for the temporal stability, a lower value is better.  ...

2005 Proceedings of the 13th annual ACM international conference on Multimedia - MULTIMEDIA '05  
In this paper, we propose a unified shot boundary detection framework by extending the previous work of graph partition model with temporal constraints.  ...  To detect both the abrupt transitions (CUTs) and gradual transitions (GTs, excluding fade out/in) in a unified way, we incorporate temporal multi-resolution analysis into the model.  ...  Despite the remaining problems above, we believe that the proposed framework may be a promising method for nearly perfect temporal segmentation of videos.  ...
