Edge detection in glass fragmentation image
Xiaohong Liu · Jisuanji gongcheng · 2005
Based on the characteristics of glass fragmentation images,a process was proposed.It first combined noise reduction,a traditional edge-detection operator,and threshold segmentation to produce an initial binary image partition.Then it applied the distance function to reconstruct and inverse it.Finally it used the watershed transformation based on chain code to obtain the whole segmentation image of fragmented glass.The final image can be used in testing safety glasses, for example to analyze and count the number of fragments.
