Abstract: The graph-based transform has recently emerged as an effective tool for compressing some special signals such as depth images in 3D videos. However, one limitation of this approach is that ...

The graph-based block transform recently emerged as an effective tool for compressing some special signals such as depth images in 3D videos. However, in existing methods, overheads are required to ...

Abstract: In this work, we concentrate on the Nonconvex Piecewise Linear Network Flow Problems (NPLNFP) with discontinuous piecewise linear cost functions. Based on the piecewise linearity and ...
