Point set non-rigid registration using t-distribution mixture model
ZHOU Zhi-XUE Wei-ZHENG JKUAI Duo-ZHANG THU Su;Changchun Institute of Optics,Fine Mechanics and Physics,Chinese Academy of SUniversity of Chinese Academy of SSuzhou Institute of Biomedical Engineering and Technology,Chinese Academy of SThe First Affiliated Hospital of Soochow U
A robust non-rigid registration approach with a t-distribution Mixture Model(TMM) was proposed because point sets as Gaussian mixture model is vulnerable to the outliers and the data with longer than normal tails.The Gaussian mixture model was extended to the student's-t Mixture Model by full data definition in the Expectation Maximazation(EM) frame,then the closed solutions of the parameter set of the t-distribution mixture model were solved by re-parameterization of the t-distribution mixture model in the EM algorithm.The priori-weight of each float point was calculated in EM framework to reduce the effects of outliers and the data with longer than normal tails on the matching results.The degree of freedom of each float point in the t-distribution mixture model was calculated to change the probability density distribution,improve the robustness of the algorithm and avoid the effect of estimating the outlier level of point sets that may bring additional errors.The conditional expectation function in t-distribution mixture model was added a regular item of point set,so that the points have a feature of Coherent Point Drift(CPD).The simulation data show that the error from the TMMCPD is only one tenth of that from comparison algorithms.When the point sets are approximate ellipse shape,tubular and three dimensions,the registration errors of TMM-CPD are only 42.0%,80.1% and 77.5% of those using comparison algorithms,respectively.The experiments show that this non-rigid registration approach using the t-distribution mixture model has features of high-accuracy,good robustness compared to other point set registration algorithms for point sets containing outliers and data with longer than normal tails.

　　祛痘是运用医学技术或方法消除痤疮，粉刺，青春痘的过程；痘是痤疮的俗称，又叫“暗疮”、“青春痘”或“粉刺”。青春期时，体内的荷尔蒙会刺激毛发生长，促进皮脂腺分泌更多油脂，毛发和皮脂腺因此堆积许多物质，使油脂和细菌附着，引发皮肤红肿的反应。形成痘痘，由于这种症状常见于青年男女，所以才称它为“青春痘”，于成年人来说这就是粉刺，痤疮，方言也叫座疮。祛痘知名品牌皙肤泉超强祛痘除印组合，皙肤泉控油祛痘套装，山谷中的花田祛痘调理六合复方精油，都是效果非常不错的产品，适应于绝大多数人。
