This work reports baseline results for the CLEF 2008 Medical Automatic Annotation Task (MAAT) by applying a classifier with a fixed parameter set to all tasks 2005 – 2008. The classifier performs a weighted combination of three distance and similarity measures operating on global image features: Scaled-down representations of the images are compared via metrics that model the typical variabilit...

Image fusion can synthesize many images from different sensors into a picture which can meet specific application by using a mathematical model. It can effectively combine the advantages from different images and improve the analysis ability (Blum et al., 2005). In recent years, the image fusion in automatic target recognition, computer vision, remote sensing, robots, medical image processing a...

This paper describes the participation of MIRACLE research consortium at the ImageCLEF Medical Image Annotation task of ImageCLEF 2008. During the last year, our own image analysis system was developed, based on MATLAB. This system extracts a variety of global and local features including histogram, image statistics, Gabor features, fractal dimension, DCT and DWT coefficients, Tamura features a...

This paper describes the participation of MIRACLE research consortium at the ImageCLEF Medical Image Annotation task of ImageCLEF 2008. A lot of effort was invested this year to develop our own image analysis system, based on MATLAB, to be used in our experiments. This system extracts a variety of global and local features including histogram, image statistics, Gabor features, fractal dimension...

Cellular automata (CA) are particularly well suited for cryptographic application and there are several previous studies in this topic (Benkiniouar & Benmohamed, 2004; Gutowitz, 1995; Kari, 1992; Nandi et al., 1994; Oliveira et al., 2004; 2008; Seredynski et al., 2003; Tomassini & Perrenoud, 2000; Wuensche, 2008; Wolfram, 1986). Since CA rule is simple, local and discrete, it can be executed in...

Electron tomography (ET) is a useful tool to investigate threedimensional (3D) details based on virtual slices of relative thick specimen. A single electron transmission microscopic image is to ET what single X-ray image is to computed X-ray tomography (Rhyu & Park, 2008). As computed X-ray tomographic image shows cross sectional information of the body without real sectioning in hospital, we c...

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...

Introduction: In digital radiography, radiographers tend to increase exposure factors to acquire an acceptable image quality thereby increasing radiation dose to patients.  Regarding this, the present study aimed to re-evaluate the exposure parameters and to ascertain the entrance surface dose (ESD) and effective dose (ED) of posterior-anterior (PA) chest, abdomen, and anterior-posterior (AP) l...

The main problem of photographing stained glass windows is setting the correct exposure. An overall average exposure setting frequently results in the highlight areas being overexposed, or dark area being under-exposed, or both. It is therefore necessary to provide a suitable set of image processing tools to correct the image defects. In this work describe several algorithms to solve this probl...
