3D End-to-End Boundary-Aware Networks For Pancreas Segmentation

The JPEG Pleno light field encoder can perform disparity compensated view prediction for coding HDCA views. For operating in this prediction mode, disparity maps need to be communicated along with the 2D array of views. in this work we explore a new adaptive wavelet transform for coding disparity maps, known as tri-breakpoint (TriBRK) dependent DWT, that is currently being considered as part of JPEG 2000 Part-17 extensions. We show that the scalable TriBRK dependent DWT, defined on a hierarchical triangular grid, provides rate-distortion gains for coding disparity maps and improves the compression of HDCA views that rely upon the disparity information. Visual quality improvements are also observed, specifically at object boundaries of decoded views.
