Seam carving is a content-aware resizing method. Based on a seam carving approach to obtain semantic video compression, the non salient parts of the video are suppressed and the reduced sequence is encoded with H.264/AVC. To avoid a large overhead to encode the seams, the seams are regrouped together and approximated. In this paper, after the approximation, the seams are resynthesized similarly to the process carried out at the decoder side. The resulting information is used to define a new reduced sequence. This closed loop process leads to less geometric deformation when the initial seams are spatially scattered in the sequence.
