Simultaneous Registration and Bias Correction of Brain Intra-operative MR Images

Jean-Philippe Thiran, Torsten Butz, Benoît Macq, Mathieu De Craene

Intra-operative MR imaging is an emerging tool for image guided (neuro)surgery. Due to the small size of the magnets and the short acquisition time, the images produced by such devices are often subject to distortions. In this work, we show the particular ...

Perspectives on panoramic photography

David Hasler

Digital imaging brings a new set of possibilities to photography. For example, little pictures can be assembled to form a large panorama, and digital cameras are trying to mimic the human visual system to produce better pictures. This manuscript aims at de ...

Automatic Morphometry of Nerve Histological Sections

Olivier Cuisenaire, Benoît Macq

A method for the automatic segmentation, recognition and measurement of neuronal myelinated fibers in nerve histological sections is presented. In this method, the fiber parameters i.e. perimeter, area, position of the fiber and myelin sheath thickness are ...

Distance transformations: fast algorithms and applications to medical image processing

Olivier Cuisenaire

Medical image processing is a demanding domain, both in terms of CPU and memory requirements. The volume of data to be processed is often large (a typical MRI dataset requires 10 MBytes) and many processing tools are only useful to the physician if they ar ...

A Pyramid Approach to Subpixel Registration Based on Intensity

Michaël Unser, Philippe Thévenaz

We present an automatic sub-pixel registration algorithm that minimizes the mean square difference of intensities between a reference and a test data set, which can be either tri-dimensional (3-D) volumes or bi-dimensional (2-D) images. It uses spline proc ...

Geometric Aspects in 3D Biomedical Image Processing

Michaël Unser, Philippe Thévenaz

We present some issues that arise when a geometric transformation is performed on an image or a volume. In particular, we illustrate the well-known problems of blocking, blurring, aliasing and ringing. Although the solution to these problems is trivial in ...

Unsupervised Connectivity-Based Thresholding Segmentation of Midsagittal Brain MR Images

Michaël Unser

In this paper, we propose an algorithm for automated segmentation of midsagittal brain MR images. First, we apply thresholding to obtain binary images. From the binary images, we locate some landmarks. Based on the landmarks and anatomical information, we ...

UV irradiation induced transformation of germanosilicate glass structure

René Salathé, Hans Georg Limberger

Deformation of Raman spectra of germanosilicate core fibers before and after UV irradiation were observed. It indicates the photoinduced transformation of glass structure. One of the possible models of such transformation is proposed. ...

Finding Lines Under Bounded Error

A new algorithm for finding straight lines in images under a bounded error model is described. The algorithm is based on a hierarchical and adaptive subdivision of the space of line parameters. It measures errors in image space and thereby guarantees that ...
