Feature clustering of intracranial pressure time series for alarm function estimation in traumatic brain injury.

Objective: The conventional application of intracranial pressure (ICP) monitoring of traumatic brain injury (TBI) patients consists merely in the acquisition of ICP values in discrete time and their comparison to the established ICP threshold. An exceeding of this threshold triggers a special emergency treatment protocol. This paper addresses the possibility of making use of the rich information latent in the ICP records of known vital and fatal outcomes gathered during real clinical practice of treating TBI patients.

Robust object recognition under partial occlusions using NMF.

In recent years, nonnegative matrix factorization (NMF) methods of a reduced image data representation attracted the attention of computer vision community. These methods are considered as a convenient part-based representation of image data for recognition tasks with occluded objects. A novel modification in NMF recognition tasks is proposed which utilizes the matrix sparseness control introduced by Hoyer.

Improvement of band segmentation in Epo images via column shift transformation with cost functions.

In recent years, the development of methodology and laboratory techniques for doping control (DC) of recombinant erythropoietin (rEpo) has become one of the most important topics pursued by doping control laboratories accredited by World Anti-Doping Agency (WADA). The software system GASepo has been developed within the international WADA project as a support for Epo doping control. Although a great number of functions for automatic image processing have been involved in this software, for Epo images with considerably distorted bands additional effort is required from the user to interactively correct the results of improper band segmentation.

GASepo-a software solution for quantitative analysis of digital images in Epo doping control.

A software has been developed that is aimed at quantitative analysis of images acquired by isoelectric focusing and double blotting procedures used for recombinant erythropoietin doping control. It represents a unified and easy-to-use tool for Epo doping experts in WADA accredited laboratories. It is based on image segmentation philosophy that enables identification of individual bands whose characteristics are needed for evaluation of the Epo doping positivity criteria.

Quantitative analysis of images in erythropoietin doping control.

The software system GASepo has been developed as a tool to visualise and analyse doping (searching for performance-enhancing drugs in sports) with recombinant erythropoietin (rEpo). Digital images derived from the separation of Epo isoforms in gels by iso-electric focusing followed by double blotting and chemiluminescence detection contain spots (bands) of characteristic shape and positions. For Epo doping control, these have to be analysed and evaluated.
