Hui Huang, Jionghui Jiang · 2009
Considering the features of virtual human images, a Laplacian operator based level set algorithm and the analytic expression of level set equation is deduced. The algorithm is implemented using narrow band method numerically. The algorithm combines the advantages of Laplacian operator which can orient the boundary accurately and the idea that level set method continuously evolves the boundary in image space. Experiments show that the algorithm calculates the result precisely with good anti-jamming property and fast computing speed. Fine results can be obtained by using this algorithm.
