A Rapid Elastic Registration Algorithm Based on Hermite Derivative Filter
Minmin Luo, Guiping Jiang, Wufan Chen · 2008
In this paper, a novel method is proposed to improve Hany Farid's elastic registration scheme. Based on Hermite orthogonal polynomial, a discrete derivative filter is designed according to the principle of least square. Using the registration results of a set of medical images with different features, the effect of Hermite derivative filter is compared with ones of difference filter and Hany Farid's optimal derivative filter, which proving that Hermite derivative filter can significantly reduce the cost-time and obtain the same registration precision simultaneously.
