Faces alive: Reconstruction of animated 3D human faces

International conference on Computational Science and Its Applications - ICCSA 2005

作者： Zhang, Yu Sim, Terence Tan, Chew Lim School of Computing National University of Singapore Singapore 117543 Singapore

This paper presents a new method for reconstructing anatomy-based, animatable facial models with minimal manual intervention. The technique is based on deforming a multi-layered prototype model to the acquired surface data in an "outside-in" manner: deformation applied to the skin layer is propagated, with the final effect of deforming the underlying muscles. In the skin layer deformation, the generic skin mesh is represented as a dynamic deformable model which is subjected to internal force stemming from the elastic properties of the surface and external forces generated by input data points and features. A fully automated approach has been developed for deforming the muscle layer that includes three types of muscle models. Our method generates animatable models from incomplete input data and reconstructed facial models can be animated directly to synthesize various expressions. © Springer-verlag Berlin Heidelberg 2005.

Nuclear Science Symposium/Medical Imaging conference

The high resolution research tomography (HRRT) is currently the most complex human brain scanner due to its ability to detect the gamma depth of interaction, its octagonal geometry, and the large number of crystals (119,808) leading to approximately 4.5 x 10(9) possible lines of response (LORs). reconstruction of dynamic studies on this scanner is particularly challenging due to the dynamic range of both, number of acquired events per frame and acquisition count rates. Some artifacts have been observed with phantom studies: here we evaluate their impact on time activity curves (TACs) and binding potential (BP) values in realistic scanning situations with the ultimate goal of defining an efficient and accurate image reconstruction protocol. Non-human primate studies were used for this purpose. We compared TACs and BPs obtained from images reconstructed with three different reconstruction algorithms, two different axial spanning configurations and detector normalization factors obtained from two different data sets. We also compared BP values obtained from scans of the same animal performed on the Siemens ECAT 963B and the HRRT under identical conditions. The statistical reconstruction methods produced nearly identical results and the impact of emission/normalization count rate mismatch was found to be effectively negligible. Likewise no image degradation due to increased axial spanning was observed. data obtained from the analytical method were less robust and in general much more sensitive to noise, thus demonstrating a suboptimal performance of this algorithm. The BP values obtained with the HRRT were by approximately 50% higher compared to those obtained in the ECAT as a result of the increased resolution of this tomograph.

6th Pacific-Rim conference on Multimedia (PCM 2005)

In this paper, we propose a panoramic mesh modeling method from multiple range data for indoor scene reconstruction. The input to the proposed method is several sets of point clouds obtained from different viewpoints. An integrated mesh model is generated from the input point clouds. Firstly, we partition the input point cloud to sub-point clouds according to each camera's viewing frustum. Then, we sample the partitioned sub-point clouds adaptively and triangulate the sampled point cloud. Finally, we merge all triangulated models of sub-point clouds to represent the whole indoor scene as one model. Our method considers occlusion between two adjacent views and it filters out invisible part of point cloud without any prior knowledge. While preserving the features of the scene, adaptive sampling reduces the size of resulting mesh model for practical usage. The proposed method is modularized and applicable to the other modeling applications which handle multiple range data.

We report on the further development of our previously described spectroscopic imaging technique based on time-resolved interferometric measurements of laser-induced thermoelastic expansion (POlSe: Pulsed Optoelastic Interferometric Spectroscopy and Imaging). We show the capability of POISe to form tomographic images of tissue phantoms and live animal tissues. By performing image reconstruction on data sets acquired from several tissue-like phantoms we demonstrate the ability of POISe to provide better than 200 mu m spatial resolution in a strongly scattering medium (mu(I)(s)=1.5/mm). Additionally we demonstrate the ability of POISe to image chicken chorio-allantoic membrane (CAM) blood vessels through a 6-10 mm layer of Intralipid with mu(I)(s)=0.75/mm.

We present our results on development of algorithms for image reconstruction in optical computed-tomography microscopy. The optical computed-tomography microscope with light modulation, recently developed by our group at the BC Cancer Research Centre is a novel imaging device for three-dimensional visualization and quantitative analysis of absorption-stained biological samples. The angles for projection in the system are limited to the range of 0 <= phi <= 135 degrees by the numerical aperture of the illumination objective. For the limited-angle tomography problem we have developed several reconstruction algorithms. One algorithm is based on the Radon transformation and assumes parallel ray projections. In order to compensate for limited data, several reconstructions are generated from several sets of projections of a specimen, acquired at different orientations of parallel-ray light scanning. The reconstructions are combined together using a vote criteria to create a final volume. Another reconstruction algorithm developed by the group employs both transform-based and iterative methods to address the limited-angle reconstruction problem. In this algorithm the trans form-based method is used as an initial starting point for the following iterative reconstruction. A feedback correction of the reconstruction imauc is made on each iteration step. The method enables to incorporate previously known information about the object into the reconstruction process. The algorithm improves reconstruction accuracy at a reasonable computational cost and programming commitment. Three-dimensional microscopic images of quantitatively absorption-stained cells have been reconstructed with the resolution better than 6 microns.

29th International Cosmic Ray conference

作者： de Souza, v. Univ Sao Paulo BR-04508031 Sao Paulo Brazil

The impact of the lateral distribution of light in extensive air showers on the detection and reconstruction of shower profiles is investigated for the Auger fluorescence telescopes. Based on three-dimensional simulations, the capability of the Auger telescopes to measure the lateral distribution of light is evaluated. The ability to infer the actual lateral distribution is confirmed by the comparison of detailed simulations with real data. The contribution of pixels located far from the axis of the shower image is calculated and the accepted signal is rescaled in order to reconstruct a correct shower profile. The analysis presented here shows that: (a) the Auger telescopes are able to observe the lateral distribution of showers and (b) the energy corrections to account for the signal in outlying pixels can exceed 10%, depending on shower geometry.

Utilization of tools during surgical interventions sets the problem of their accurate localization within biological tissue. The ultrasound imaging represents an inexpensive and a flexible approach for a real-time image acquisition of tissue structure with metal instruments. There are several difficulties involving processing of ultrasound images: Their noisy nature makes the localization task difficult;the objects appear irregular and incomplete. Our task is to determine the position of a curvilinear electrode in biological tissue from a three-dimensional ultrasound image. Initially, the data are segmented by thresholding and processed with the randomized version of the RANSAC (R-RANSAC) algorithm. The curvilinear electrode is modeled by a three-dimensional cubic curve. Its shape is subject to check using a curvature measure in the hypothesis evaluation step of the R-RANSAC algorithm. Subsequently, we perform the least squares curve fitting to the data that have been marked by the R-RANSAC as the ones corresponding to the sought object. The position estimation is optimal with respect to the mean square criterion. Finally, the localization of the electrode tips is carried out by a hypothesis testing on the distances between projections of inliers on the estimated curve. The algorithm has been tested on real three-dimensional ultrasound images of a tissue mimicking phantom with a curvilinear object. from the results, we conclude that the method is very stable even if the data contain high percentage of outliers. The computational cost of the algorithm shows the possibility of real-time data processing.

reconstruction of myocardial short-scan SPECT images

In myocardial perfusion SPECT imaging the effect of photon attenuation may introduce artifacts in the reconstructed image due to the highly non-uniform distribution of tissue in the thorax region, potentially resulting in false-positive interpretations. It was the general consideration that the adequate compensation of photon attenuation requires, that the emission data be measured at projection angles over 2π in the case of the attenuation medium is inhomogeneous. The reduction of the scanning angle in SPECT imaging may be desirable because it can reduce scanning time and thereby minimize patient-motion and other artifacts. In SPECT myocardial imaging emission data is measured historically at projection angles over π from the right anterior oblique (RAO) to the left posterior oblique (LPO). This configuration results in better image contrast and, in some cases, betters spatial resolution. However, in this case the reconstructed image may suffer more severely from geometric distortion than 2π angular sampling. It has been proven recently in analytical computer simulation studies that the data function over 2π in SPECT with non-uniform attenuation contains redundant information;therefore the scanning angle theoretically can be reduced from 2π to π without loss of information. In this study our goal was to investigate how the various short-scan SPECT scheme configurations works in a real myocardial SPECT imaging system with highly inhomogeneous attenuating medium using attenuation correction. The measured projection images were reconstructed using the Maximum Likelihood Expectation Maximization algorithm with attenuation correction. The reconstructed slices of the various short-scan configurations and the full-scan slices were compared by a cardiac stress/rest software package. © 2005 IEEE.

A finite-volume model of the cerebrospinal fluid (CSF) system encompassing the third ventricle and the aqueduct of Sylvius was used to reconstruct CSF velocity and pressure fields based on MRI data. The flow domain geometry was obtained through segmentation of MRI brain anatomy scans. The movement of the domain walls was interpolated from brain motion MRI scans. A constant pressure boundary condition (BC) was specified at the foramina of Monro. A transient velocity BC reconstructed from velocimetric MRI scans was employed at the inferior end of the aqueduct of Sylvius. It could be shown that a combination of MRI scans and computational fluid dynamics (CFD) simulation can be used to reconstruct the flow field in the third ventricle. Pre-interventional knowledge of patient-specific CSF flow has the potential to improve neurosurgical interventions such as shunt placement in case of hydrocephalus.

There are various segmentation and surfacing methods to create CAD models from measured data. First the difficulties of creating a good surface structure over a polygonal mesh are investigated, followed by investigating the most important approaches according to the amount of user interaction, computational efficiency and surface quality. References to commercial systems are also added. The focus of the paper is to present (i) automatic surfacing and (ii) functional decomposition. New demands and emerging technologies are also identified to trace out current trends in digital shape reconstruction. © Springer-verlag Berlin Heidelberg 2005.
