Distribution Measurement of Space Spherules Based on Voxels Marking Number Method
Jingfeng Zhang · Jisuanji gongcheng · 2012
A measurement algorithm of voxels marking number based on slice images is presented.After preprocessing the CT image sequence,a point cloud model is built.The number mark for voxels is signed orderly from outside to center.Through local extremum search,the body-centers are got after downsizing.Statistics are completed using mark values of the body-centers.Experimental results show that the count and distribution of space spherules existed adhesion can be accurately measured by this method,when the random point noise probability is within 35%.And the volume estimation error is less than 5%.
