“…The accuracy of CFR has always been controversial (Wilkinson, 2004). A number of tprevious empirical studies have therefore employed qualitative and quantitative accuracy tests (Stephan and Cicolini, 2008;Claes et al, 2010;Fernandes et al, 2012;Lee et al, 2012) and successful forensic cases (South Wales Police Museum, 2005;Algemeen, 2009;BBC, 2013) also demonstrate that CFR techniques can provide enough resemblance to the real faces to enable recognition.…”

Craniofacial reconstruction (CFR) is a technique used to rebuild the living facial appearance onto a skull in order to recognise or identify an individual. This technique is primarily employed in forensic investigation, but also utilised in archaeological research to recreate the faces of paleontological and archaeological humans. In this study, the face of a 17 th century historical figure from Korea was reconstructed utilisingcomputerized tomography from the mummified remains. A geographic surface comparison programme was employed to evaluate the accuracy of the CFR produced using a three-dimensional computerized modelling system. Analysis of the facial tissue depth discrepancies demonstrated that the CFR may have acceptable resemblance to the living face of the historical individual. Using computerised graphic technology, the CFR outcome, along with the archaeological information about the hair style, ornaments, and dress discovered in the tomb, a portrait-styled in the typical drawing trend from the era was created. The research suggests that current CFR techniques can provide an accurate portrait drawing of historical figures in Korea.

“…Facial recognition and individualization is a specialized human ability and a widely accepted identification and authentication method [8][9][10][11]. Craniofacial reconstruction is a technique focused on identification of the deceased, which has its foundation in facial anatomy and its relationship to the underlying skull [12][13][14]. In theory, a DNA-based facial composite should be possible given the compelling evidence that facial features are under strong genetic control [15].…”

“…Given a scale l 0 , the boundary B 0 will shrink into interior with l 0 step and get a contour B 0 which is indicated by a point Q 0 ∈ B 0 in Figure 6d, while the counter B 1 shrink oppositely on the global mesh and get a contour B 1 which is indicated by a point Q 1 ∈ B 1 in Figure 6d. The stitching method is to find a pair of interpolation functions f 0 , f 1 have the following conditions: (14) There are many interpolation methods can be used to meet the above conditions, such as RBF function. For convenience, we adopt the above TPS to solve the interpolation.…”

“…The reconstruction result is generally determined by the experience of practitioners. To reduce reconstruction time and eliminate subjective biases, different computeraid craniofacial reconstruction methods have been proposed [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The state-of-the-art of the computer-aid craniofacial reconstruction have comprehensively been reviewed in the surveys [18][19][20][21].…”

“…So many deformation methods are proposed to model the non-rigid shape deformation of http://asp.eurasipjournals.com/content/2012/1/217 skull and face, such as radial basis functions (RBF) [22,23], or more exactly, a thin plate spline (TPS)-based deformation [12,24,25] for its smoothness. Instead of using fixed template, the recently proposed statistical craniofacial reconstruction methods [12][13][14][15][16][17] construct a type of deformable model from a set of 3D heads by the principle component analysis (PCA) technique. The statistic deformable model can be regarded as a dynamic template for the given skull.…”

Craniofacial reconstruction from skull has deeply been investigated by computer scientists in the past two decades because it is important for identification. The dominant methods construct facial surface from the soft tissue thickness measured at a set of skull landmarks. The quantity and position of the landmarks are very vital for craniofacial reconstruction, but there is no standard. In addition, it is difficult to accurately locate the landmarks on dense mesh without manual assistance. In this article, we propose an automatic craniofacial reconstruction method based on a hierarchical dense deformable model. To construct the model, we collect more than 100 head samples by computerized tomography scanner. The samples are represented as dense triangle mesh to model face and skull shape. As the deformable model demands all samples in uniform form, a non-rigid registration algorithm is presented to align the samples in point-to-point correspondence. Based on the aligned samples, a global deformable model is constructed, and three local models are constructed from the segmented patches of the eye, nose, and mouth. For a given skull, the global and local deformable models are matched with it, and the reconstructed facial surface is obtained by fusing the global and local reconstruction results. To validate our method, a face deformable model is constructed and the reconstruction results are evaluated in its coefficient domain. The experimental results indicate that the proposed method has good performance for craniofacial reconstruction.
