ICASSP 2016accepted

The lossless compression of Whole Slide pathology Images (WSIs) using HEVC is investigated in this paper. Recently proposed intra-prediction algorithms based on differential pulse-code modulation (DPCM) and edge prediction provide significant bitrate improvements for a wide range of natural and scre…

Rate control for lossless region of interest coding in HEVC intra-coding with applications to digital pathology images

Victor Sanchez, Francesc Auli-Llinas, Rahul Vanam, Joan Bartrina-Rapesta

ICASSP 2015accepted

This paper proposes a rate control algorithm for lossless region of interest (RoI) coding in HEVC intra-coding. The algorithm is developed for digital pathology images and allows for random access to the data. Based on an input RoI mask, the algorithm first encodes the RoI losslessly. According to t…
