    Summary form only given. Publicly available data from disparate sources are frequently combined for subsequent statistical analyses. Data from different sources are often measured or associated with different geographic or spatial units. Combining them for analysis usually requires prediction of one or more of the variables of interest. Here it is assumed that health outcomes and related covariate... View full abstract»

  • Head posture detection using skin and hair information

    Publication Year: 2012, Page(s):1 - 4
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (398 KB) | HTML iconHTML

    This paper addresses a novel head posture detection algorithm to recognize human-computer interactions. A pattern training based image segmentation algorithm is used to detect the skin and hair of students. A simple and efficient human presence detection and gaze direction estimation method is then proposed based on the segmentation results. Finally, the proposed algorithm is tested on ten differe...

  • Simultaneous affine registration of multiple shapes

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (816 KB) | HTML iconHTML

    The problem of simultaneously estimating affine deformations between multiple objects occur in many applications. Herein, a direct method is proposed which provides the result as a solution of a linear system of equations without establishing correspondences between the objects. The key idea is to construct enough linearly independent equations using covariant functions, and then finding the solut... View full abstract»

  • Appearance control for human material perception manipulation

    Publication Year: 2012, Page(s):13 - 16
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1645 KB) | HTML iconHTML

    We describe a new concept of human visual perception manipulation using illumination projection. The idea is to alternate material appearance of an object using projector camera feedback and a manipulation technique of an image-based material appearance. Unlike the simple display technique, our approach can manipulate human material perception for any object using the appearance control technique ... View full abstract»

  • Bone suppression in chest radiographs by means of anatomically specific multiple massive-training ANNs

    Our purpose was to separate bony structures such as ribs and clavicles from soft tissue in chest radiographs (CXRs). Although massive-training artificial neural networks (MTANNs) have been developed for suppression of ribs, they did not suppress rib edges, ribs close to the lung wall, and the clavicles well. To address this issue, we developed anatomically specific multiple MTANNs that are designe... View full abstract»

  • Seeded segmentation based on object homogeneity

    Publication Year: 2012, Page(s):21 - 24
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (359 KB) | HTML iconHTML

    Seeded segmentation methods attempt to solve the segmentation problem in the presence of prior knowledge in the form of a partial segmentation, where a small subset of the image elements (seed-points) have been assigned correct segmentation labels. Common for most of the leading methods in this area is that they seek to find a segmentation where the boundaries of the segmented regions coincide wit... View full abstract»

  • Self-training with unlabeled regions for NBI image recognition

    Publication Year: 2012, Page(s):25 - 28
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1420 KB) | HTML iconHTML

    In this paper, we propose a self-training method which uses unlabeled regions in the original images obtained from a colorectal Narrow Band Imaging (NBI) zoom-video endoscope. The proposed method first trims a number of patches from unlabeled regions in the original images and uses them as unlabeled training samples. Classifiers are trained with the available labeled samples, as well as with those... View full abstract»

  • Potts compound Markovian texture model

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (364 KB)

    This paper describes a novel multispectral parametric compound Markov random field model for texture synthesis. The proposed compound Markov random field model connects a parametric control random field represented by a hierarchical Potts Markov random field model with analytically solvable wide-sense Markovian representation for single regions. The compound random field synthesis combines the mod... View full abstract»

    Classifying images of HEp-2 cells from indirect im-munofluorescence has important clinical applications. We have developed an automatic method based on random forests that classifies an HEp-2 cell image into one of six classes. The method is applied to the data set of the ICPR 2012 contest. The previously obtained best accuracy is 79.3% for this data set, whereas we obtain an accuracy of 97.4%. Th... View full abstract»

  • Online ICP forecast for patients with traumatic brain injury

    Publication Year: 2012, Page(s):37 - 40
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (225 KB) | HTML iconHTML

    Traumatic brain injury (TBI) endangers many patients and lays great burden on the neural intensive-care units in the whole world. To improve the outcome of TBI patients, it is desirable to forecast the intracranial Pressure (ICP) so to enable timely or early interventions to control the ICP level. Past research mainly focused on ICP pulse morphology analysis and ICP waveform forecast, but results ... View full abstract»

  • Quantification of age-related brain cortex change using 3D shape analysis

    To characterize the brain changes associated with aging, we detect brain cortex variability through a spherical harmonic analysis that represents a 3D surface supported by the unit sphere through a linear combination of special basis functions, called spherical harmonics (SHs). The proposed 3D shape analysis is carried out in four steps: (i) 3D Delau-nay triangulation to construct a 3D mesh model ... View full abstract»

    The invention of wireless capsule endoscopy greatly helps physician to view small intestine images without causing much pain to patients. It becomes very popular around the world for its usability and performance. However, physician requires a long time (around 45 minutes) to examine a capsule endoscopy video generated from each examination. In this paper, we propose a new image processing method ...

  • Efficient optic cup localization based on superpixel classification for glaucoma diagnosis in digital fundus images

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (736 KB) | HTML iconHTML

    Optic cup is the primary image indicator clinically used for identifying glaucoma. To automatically localize the optic cup in fundus images, an effective and efficient superpixel classification based approach is proposed in this work, which maintains both advantages of existing pixel and window based approaches. This method provides three major contributions. First, it proposes processing of the f... View full abstract»
