Little prior image processing work has addressed estimation and classification of skin color in a manner that is independent of camera and illuminant. To this end, we first present new methods for 1) fast, easy-to-use image color correction, with specializ ...
Ductal cells of the pancreas form the epithelial lining of the branched tubes that deliver enzymes produced by pancreatic acinar cells into the duodenum. In addition, these cells secrete bicarbonate that neutralizes stomach acidity. During development, epi ...
Reactive Oxygen Species (ROS) is a family of oxygen-based active molecules, which are deeply involved in numerous crucial processes of cellular metabolism, where the redox equilibrium is very important. An imbalance between ROS and the cell ability to neut ...
The aim of this thesis is to optimize and obtain fundamental information on i) the photodetection (PD) of early stage cancers in the tracheo-bronchial tree by spectroscopic imaging of the tissue autofluorescence, ii) photodynamic therapy (PDT) applied in d ...
We present the use of an array of rectangular microelectrodes to discriminate between different resistivities in a thin, layered sample. Each electrode was 8 rum long and 200 nm thick. The electrode widths ranged from 20 to 500/mum. The electrodes were des ...
Fibroblast growth factor 2 (FGF2) has been assigned a role in melanocyte proliferation and in development of human cutaneous melanoma. We have used a transgenic mouse melanoma model in combination with mice lacking mouse FGF2 to analyse the possible implic ...
In human cutaneous malignant melanoma, a predominance of activated mutations in the N-ras gene has been documented. To obtain a mouse model most closely mimicking the human disease, a transgenic mouse line was generated by targeting expression of dominant- ...
In this paper, we present a system for anonymous visual communications. Target application is an anonymous video chat. The system is identifying faces in the video sequence by means of face detection or skin detection. The corresponding regions are subsequ ...
Can individual cells, including live cells, be imaged using hard x rays? Common wisdom until now required sophisticated staining techniques for this task. We show instead that individual cells and cell details can be detected in culture solution and tissue ...
We present improved processing of the soft amorphous ferromagnetic material for the fully integrated fluxgate magnetometer. The additional steps of polishing, chemical thinning and annealing are introduced to preserve the original material characteristics ...
