In this problem, the optimal path is one that maximizes the expected utility, with the utility function being piecewise-linear and concave. Such a utility function can be used to approximate nonlinear ...

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 it needs to ...

The use of an alphabet of line segments to compose a curve is a possible approach for curve data compression. Many approaches are developed with the drawback that they can process simple curves only.
