Discover a groundbreaking method for optimizing nonlinear functions through piecewise linearization. Explore our paper for the best approximation techniques and real-world examples.

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 ...

Piecewise smooth (PWS) images (e.g., depth maps or animation images) contain unique signal characteristics such as sharp object boundaries and slowly varying interior surfaces. Leveraging on recent ...
