Study on the Method for Removing Boundary Burr Based on Relevance of Chain Code

To the problem that how to remove the boundary burr, the property of Freeman chain code was researched, and define the correlation of the chain code based on relevance of chain code. With the feature that the correlation between the direction chain codes of point in and out of the end pixel of burr is the least, a new algorithm which is used for removing the burr by judging the correlation of Freeman chain codes is proposed. Experiment results show that the algorithm is accurate and effective.
