Low-Overhead Content-Adaptive Spatial Scalability for Scalable Video Coding

Chia-Wen Lin, Senior Member, IEEE, Chia-Ming Tsai, and Po-Chun Chen

Video Demo

We show some demo videos to compare the proposed method with uniform scaling, the retargeting scheme proposed by [Krahenbuhl et al. 2009], the retargeting scheme without cropping operator proposed by [Wang et al. 2011], and the retargeting scheme proposed by [Yen et al. 2011], respectively.

We compare the proposed CASS-SVC coding method with SVC (JSVM 9.18) under different QP conditions. Note, due to the storage limitation, only partital results are selected and each demo video file is archived in Zip format.
