This paper presents a face registration method and a surgical instrument tracking method for Image-guided Surgical Navigation System (ISNS). In ISNS, we start the process by reconstructing 3d point cloud of patient using a proactive structured light visual system and then accurately complete face registration based on Iterative Closest Point (ICP) algorithm. We utilize special markers to represent...
Fast, accurate registration between image space and patient space is the key point to surgical navigation system. In this paper, we research and implement an face matching method based on biometri. Against to the smooth, textured feature of human face, we built a proactive structured light vision system, to get patient's facial point cloud, proposed and implemented a rough face point cloud registration...
By measuring the local diffusion properties of water molecules in three dimensions, diffusion-weighted magnetic resonance imaging (DW-MRI) can provide invaluable information on the white matter architecture in the brain in vivo and non-invasively. Q-ball imaging (QBI) is a widely used high angular resolution diffusion imaging (HARDI) technique for orientation density function (ODF) with Funk-Radon...
Image fusion was one of the most important technology of pattern recognition. This paper proposed a fast superresolution image reconstruction algorithm basing on image sequences. Iterative back-projection (IBP) technique was used to construct high resolution from image sequences. roughly registered basing on feature and then use Registration algorithm basing on Gray to optimize the result. Iterative...
