We describe our approach to the ImageCLEF-VisualConcept 2008 task. Our method is based on image segmentation, using a feature vector describing the visual content of image segments or the entire image. Logistic regression was used for classi cation. Images were segmented by a home developed segmenter. While in this preliminary report classi cation by global image features performed best, prelim...

We measured the polarized and azimuthal dependencies of optical second harmonics generation (SHG) on polished surfaces of ZnSe(100) single crystal surface in air, using a fundamental wavelength of 1.06μm. By considering both, the bulkand surfaceoptical nonlinearities within the electric dipole approximation, we analysed the data for all four combination of pand s-polarized incidence and output....

252x252 (left) and 384x384 (right). SAP-EPI and RS-EPI datasets were acquired in equivalent scan times of 1:24min/volume. Fig 3: (a) Scan-timenormalized noise maps (i.e. accounting for the maximum number of slices) of distortion-correctedSAP-EPI and RS-EPI calculated over six b = 0 scans (matrix size=384). (b) A RSEPI 384 image is blurred by a Gaussian kernel to achieve the same SNR as SAPEPI, ...

The current study provides a quantitative assessment of three-dimensional spine motion during targetdirected trunk movements in sitting. Subjects sat on an elevated surface, without foot support, and targets were placed in five directions, at three subject-specific distances (based on trunk height). Subjects were asked to lean toward the target, touch it with their head, and return to upright s...
