Generalized selective data pruning for video sequence

In this paper, we extend a rate-dependent content-aware image retargeting method, generalized selective data pruning, to video sequence. It is regarded as a spatial-domain video retargeting, i.e., reduction of the spatial video size, with a rate-dependent property for side information. It is realized by the piecewise linear approximation of seam carving. The side information bitrate for video retargeting can vary depending on the control parameter and is negligible to transmit with the encoded video bitstream while the method maintains video retargeting performance.
