Operation in minimally invasive surgery is more difficult since the surgeons perform operations without haptic feedback or depth perception. Moreover, the field of view perceived by the surgeons through endoscopy is usually quite limited. The goal of this paper is to allow surgeons to see wide-angle images from endoscopy without the drawback of lens(More)
This paper presents an advanced augmented reality system for spinal surgery assistance, and develops entry-point guidance prior to vertebroplasty spinal surgery. Based on image-based marker detection and tracking, the proposed camera-projector system superimposes pre-operative 3-D images onto patients. The patients' preoperative 3-D image model is(More)
The new data structure, the bilateral grid, was presented by Jiawen et al. to make bilateral filter algorithm become simple implementation. Based on the data structure, the GPU CUDA-based optimization is proposed to have more efficiency in using GPU shared memory and massive multithreading. Meanwhile, a commercial application, the video 2d to 3d conversion(More)
