international Conference on 3d Imaging, Modeling, processing, visualization and transmission (3dIMPVT)

作者： R. Sablatnig C. Menard Institute of Computer Aided Automation Pattern Recognition and Image Processing Group University of Technology Vienna Wien Austria

The activation of ancient vessel-fragments is a time consuming but important task for archaeologists. The basis for classification and reconstruction is the profile which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Hence the position of a fragment (orientation) on a vessel is important. In this work the estimation of the axis of rotation out of range data by using a Hough inspired method is proposed. In order to avoid outliers a robust method for estimation of the axis is used. Classification and reconstruction are performed in a bottom-up manner using a description language, which holds all features of the fragment as primitives and all properties among features as relations. Classification of newly found fragments of unknown type is performed by comparing the description of the new fragment with the description of already classified fragments by completing graph similarity. The sub-graph with the highest similarity is then used to reconstruct the complete vessel out of the fragment.

作者： K. Claes T.P. Koninckx H. Bruyninckx Department of Mechanical Engineering ESAT Leuven Belgium Department of Electrical Engineering ESAT Leuven Belgium

This paper describes how to automatically extract the presence and location of geometrical irregularities on a surface of revolution. To this end a partial 3d scan of the workpiece under consideration is acquired by structured light ranging. The application we focus on is the detection and removal of burrs on industrial workpieces. Cylindrical metallic objects cause a strong specular reflection in every direction. These highlights are compensated for in the projected patterns, hence 'adaptive 3d scanning'. The triangular mesh produced is then used to identify the axis and generatrix of the corresponding surface of revolution. The search space for finding this axis is four dimensional: a valid choice of parameters is two orientation angles (as in spherical coordinates) and the 2d intersection point with the plane spanned by two out of three axis of the local coordinate system. For finding the axis we test the circularity of the planar intersections of the mesh in different directions, using statistical estimation methods to deal with noise. Finally the 'ideal' generatrix derived from the scan data is compared to the real surface topology. The difference identifies the burr. The algorithm is demonstrated on a metal wheel that has burrs on both sides. Visual servoing of a robotic arm based on this detection is work in progress.

In this paper we present our dual-Beam Structured-Light Scanner (dSLS), a scanning system that generates range maps much richer than those obtained from a conventional structured-light scanning system. Range maps produced by dSLS require fewer registrations for 3-d modeling. We show that the dSLS system more easily satisfies what are often difficult-to-satisfy conditions for determining the 3-d coordinates of an arbitrary object point. Two specific advantages of dSLS over conventional structured-light scanning are: (1) A single scan by the dSLS system is capable of generating range data on more surfaces than possible with the conventional approach using the same number of camera images. And (2) since the data collected by dSLS is more free of self-occlusions, the object needs be examined from a smaller number of viewpoints.

IEEE international symposium on Electromagnetic Compatibility (EMC)

作者： I. Erdin Nortel Networks Limited Ottawa ONT Canada

A genetic algorithm-based method is presented to model the interconnect discontinuities in multi-Gb/s systems. In the proposed algorithm, only the s11-parameter of a discontinuity is needed. The data can be obtained either from measurements or 3d-electromagnetic simulations. The measurement/simulation results are processed with genetic algorithm optimization technique (GAOT) to compute the values of lumped circuit components that model the discontinuity. Eliminating the need for measurement/simulation and post-processing for all entries of the S-parameter matrix as well as de-embedding, the proposed algorithm improves the computational cost while preserving the accuracy of the model. The results of the algorithm show good agreement to measurements.

作者： A. Certain W. Stuetzle Manifold Graphics Inc. USA Department of Statistics University of Washington USA

We sketch the design of a simple lower body scanner with two scan heads, positioned in front of and behind the body. The scan heads are very simple, and we believe that the scanner could be built for less than $10 K. We then describe a simple model for the lower body consisting of two stacks of ellipses, and an algorithm for fitting this model to the points and silhouettes produced by the scanner. We outline a way of extracting body dimensions from this model and discuss in detail our method to determine a subject's crotch level, a rather difficult problem. Finally, we present simulation results on the expected accuracy of the body dimensions, obtained by means of a scanner simulator.

作者： Yu Zhang T. Sim Chew Lim Tan Department of Computer Science School of Computing National University of Singapore Singapore

This paper presents a new method for reconstructing animated, anatomy-based facial models of individuals from range data with minimal manual intervention. A prototype model with a multi-layer skin-muscle-skull structure serves as the starting point for our method. After the global adaptation, the skin mesh of the prototype model is represented as a dynamic deformable model which is deformed to fit scanned data according to internal force stemming from the elastic properties of the surface and external forces produced from the scanned data points and features. The underlying muscle layer that consists of three types of facial muscles is automatically adapted. According to the adapted skin and muscle structures, a set of automatically generated skull feature points is transformed to drive a volume morphing of the template skull model for skull fitting. The reconstructed model realistically reproduces the shape and features of a specific person and can be animated instantly.

In this research, we propose a multi-step method for automatic segmentation of the hip femoral and acetabular cartilages from CT images. differentiation of the acetabular and femoral cartilages in conventional CT images due to very narrow space and low intensity of the articular space is very difficult. For this reason, MRI of the hip under continuous leg traction is the choice for assessment of the hip articular cartilage. However, this procedure is time consuming, painful, and hence inconvenient. By injecting the contrast media in the hip during data acquisition, we separated the femoral and acetabular cartilage from each other. The multi-step approach for segmentation of the femoral and acetabular cartilages is as follows. We first enhance the dynamic range and contrast of the data set by a conventional procedure. We then estimate the center of the femoral head utilizing a Hough transform. The estimated center is used as a pivotal point for beginning the process. Next, based on anatomical knowledge about the femoral head shape and size, we derive a region of interest (ROI) for further operations. In this case, by employing an Image Bottom Hat technique and anatomical knowledge about the curved shaped of the cartilages, we extract the valleys between contrast media and hip bones. The valley between the contrast media and femoral head and pelvis bone is associated with the femoral and acetabular cartilages. The anatomical assumptions we apply in this research is valid in most hip joint images. After segmentation, we present a 3d visualization and thickness map estimation of the hip femoral and acetabular cartilages. The proposed model is successfully applied to fourteen sets (3584 images) of actual in vivo hip CT data.

Video-rate registered range and intensity data are at reach of current sensor technology. This wealth of data can be profitably exploited in order to estimate rigid motion parameters as the approaches to 3-d motion estimation, based on the optical flow of both types of data, indicate. This work introduces an alternative for 3-d motion estimation based on the Fourier transform of the 3-d intensity function implicitly described by the registered time-sequences of range and intensity data. The proposed procedure can lead to an unsupervised method for 3-d rigid motion estimation. This method has several advantages related to the fact that it uses the total available information and not sets of features. With respect to memory occupancy the use of a time-sequence of a 3-d intensity function represents a considerable data reduction with respect to a pair of time-sequences of 2-d functions. The proposed technique, which extends to the 3-d case previous frequency domain estimation algorithms developed for the planar case, retain their robustness.

POCO: 3d Pose and Shape Estimation with Confidence

POCO: 3D Pose and Shape Estimation with Confidence

The regression of 3d Human Pose and Shape (HPS) from an image is becoming increasingly accurate. This makes the results useful for downstream tasks like human action recognition or 3d graphics. Yet, no regressor is perfect, and accuracy can be affected by ambiguous image evidence or by poses and appearance that are unseen during training. Most current HPS regressors, however, do not report the confidence of their outputs, meaning that downstream tasks cannot differentiate accurate estimates from inaccurate ones. To address this, we develop POCO, a novel framework for training HPS regressors to estimate not only a 3d human body, but also their confidence, in a single feed-forward pass. Specifically, POCO estimates both the 3d body pose and a per-sample variance. The key idea is to introduce a dual Conditioning Strategy (dCS) for regressing uncertainty that is highly correlated to pose reconstruction quality. The POCO framework can be applied to any HPS regressor and here we evaluate it by modifying HMR, PARE, and CLIFF. In all cases, training the network to reason about uncertainty helps it learn to more accurately estimate 3d pose. While this was not our goal, the improvement is modest but consistent. Our main motivation is to provide uncertainty estimates for downstream tasks; we demonstrate this in two ways: (1) We use the confidence estimates to bootstrap HPS training. Given unlabeled image data, we take the confident estimates of a POCO-trained regressor as pseudo ground truth. Retraining with this automatically-curated data improves accuracy. (2) We exploit uncertainty in video pose estimation by automatically identifying uncertain frames (e.g. due to occlusion) and “inpainting” these from confident frames. Code and models are available for research at https://***.

international Conference on 3d Imaging, Modeling, processing, visualization and transmission (3dIMPVT)

作者： T. Jost H. Hugli Institute of Microtechnology University of Neuchâtel Neuchatel Switzerland

The iterative closest point (ICP) algorithm is widely used for the registration of 3d geometric data. One of the main drawbacks of the algorithm is its quadratic time complexity O(N/sup 2/) with the number of points N. Consequently, several methods have been proposed to accelerate the process. We present a new solution for the speeding up of the ICP algorithm and special care is taken to avoid any tradeoff with the quality of the registration. The proposed solution combines a coarse to fine multiresolution approach with the neighbor search algorithm. The multiresolution approach permits to successively improve the registration using finer levels of representation and the neighbor search algorithm speeds up the closest point search by using a heuristic approach. Both multiresolution scheme and neighbor search algorithm main features are presented. Confirming the success of the proposed solution, typical results show that this combination permits to create a very fast ICP algorithm, with a closest point search complexity of O(N), while preserving the matching quality.
