In this paper, we present a fully automated image segmentation method based on an algorithm that provides adaptive plasticity in function approximation problems: the deformable (feature) map (DM) algorithm. The DM approach reduces a class of similar function approximation problems to the explicit supervised one-shot training of a single data set. This is(More)
In this paper a method for three-dimensional modeling of the human vocal tract based on T1-weighted MRI data sets is introduced. This includes the reconstruction of the vocal tract shape and the computation of the vocal tract midline. Reconstruction of the vocal tract shape is realized by three-dimensional region growing within the vocal tract after teeth(More)
A randomized complete block design with 3 replications (n = 432, 72 broilers per treatment) was used to evaluate the effects of electrical (ES) and vacuum stunning (VS) on broiler breast meat quality. Electrical stunning was performed by applying 11.5 V, <0.05 mA, AC to DC current for 3 s for each broiler. Vacuum stunning was accomplished by exposing the(More)
We present a complete system for image-based 3D vocal tract analysis ranging from MR image acquisition during phonation, semi-automatic image processing, quantitative modeling including model-based speech synthesis, to quantitative model evaluation by comparison between recorded and synthesized phoneme sounds. For this purpose, six professionally trained(More)
Consumers (n=316) were recruited from college football picnickers to select ribeye, sirloin, and top loin steaks from 3 price groups based on thickness (n=10 steaks per price/type combination). Constant weight steaks were assigned to these groups: P1, thinnest, $19.80/kg ribeye and top loin, $10.99/kg sirloin; P2, average thickness, $22.00/kg ribeye and top(More)
(a) q C q C q C Figure 10: (a): A two-axis gripper poised over a trapezoidal part P. There are two pairs of jaws, one formed by H 1 ; L 1 and the other H 2 ; L 2. Both pairs of jaws close in towards a central point, C. The pair H 1 ; L 1 closes in as far as possibly (without deforming the part) before H 2 ; L 2 does. (b): Possible nal poses for P after a(More)
