Abstract: This study proposes a reversible data hiding (RDH) algorithm for 3D mesh models based on the optimal three-dimensional prediction-error histogram (PEH) modification with recursive construction coding (RCC). Firstly, we design a double-layered prediction scheme to… read more here.

Abstract: Abstract Reversible data hiding (RDH) recover the original media without any distortion after extraction of the hidden data. Since massive three-dimensional (3D) mesh models have been constructed from high-dimensional image data nowadays, existing deficiencies of… read more here.
