This work presents a robust method for realtime segmentation and tracking of moving objects using depth image sequences, which is insensitive to illumination changes. We propose a novel criterion in our quadtree split-and-merge framework and effectively solves the problem of segmenting objects in complex and cluttered scenes. We also introduce a plane estimation algorithm to cope with the indistinction...
In the present study, the influence of the variation of immersion fluid volume (or air-drying time) on skull resistivity was studied. The results showed that the skull resistivity increased significantly with the increasing of air-drying time. For air-drying time of 10 min, the skull resistivity increased approximately 2 times, and for 30 min and 60 min, the skull resistivity increased significantly...
A study on correlation between structure and resistivity variations was performed for live adult human skull. The resistivities of 388 skull samples, excised from 48 skull flaps of patients undergoing surgery, were measured at body temperature (36.5degC) using the well-known four-electrode method in the frequency range of 1-4 MHz. According to different structures of the skull samples, all the 388...
