Photorealistic volume rendering of digital human slice colored images

Objective To explore a new method for the photorealistic 3D reconstruction of slice colored images from digital human data.Methods The ray casting volume rendering algorithm was improved by combining sample values and the corresponding opacity values mapped from a transfer function.Segmentation data were used to classify multiple tissues for the following direct volume rendering of digital human slice colored images.Results The proposed method achieved the goal of highly photorealistic 3D reconstruction of complex digital human tissues and organs.Conclusion The produced photorealistic volume rendering of slice colored images can accurately reflect detailed structures and color information of digital human with clear 3D boundaries.
