   Abstract : Atrial fibrillation is a common heart arrhythmia which is characterized by a missing or irregular contraction of the atria. The disease is a risk factor for other more serious diseases and the total medical costs in society are extensive. Therefore it would be beneficial to improve and optimize the prevention and detection of the disease. READ MORE

3. 7. Automatic Sleep Scoring To Study Brain Resting State Networks During Sleep In Narcoleptic And Healthy Subjects : A Combination Of A Wavelet Filter Bank And An Artificial Neural Network

   University essay from Linköpings universitet/Institutionen för medicin och hälsa

   Author : Federica Viola; [2014]
   Keywords : Automatic Sleep Scoring; Discrete Wavelet Transform; Filter Bank; Artificial Neural Network; Resting State Networks; Narcolepsy.;

   Abstract : Manual sleep scoring, executed by visual inspection of the EEG, is a very time consuming activity, with an inherent subjective decisional component. Automatic sleep scoring could ease the job of the technicians, because faster and more accurate. READ MORE

4. 8. Signal Classification Implemented by Wavelet Analysis and Support Vector Machine

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Qianyi Zhang; [2014]
   Keywords : ;

   Abstract : In this thesis, a method for signal classification has been developed and implemented on the platform of Matlab and Libsvm, which combines the techniques of wavelet analysis and support vector machine. The whole process is divided into three stages i.e. Signal Generation, Feature Extraction and Classification. READ MORE

5. 9. Grain Reduction in Scanned Image Sequences under Time Constraints

   University essay from Bildbehandling; Tekniska högskolan

   Author : Lina Stuhr; [2009]
   Keywords : image enhancement; digitalization; film grain; scanner;

   Abstract : This thesis is about improving the image quality of image sequences scanned by the film scanner GoldenEye. Film grain is often seen as an artistic effect in film sequences but scanned images can be more grainy or noisy than the intention. READ MORE

6. 10. High Resolution Satellite Data for MappingLanduse/Land-cover in the Rural-Urban Fringeof the Greater Toronto Area

   University essay from KTH/Geodesi och satellitpositionering

   Author : Maria Irene Rangel Luna; [2006]
   Keywords : ;

   Abstract : Landuse and land-cover classification from high resolution imagery has been seen as challenging by theremote sensing society. The high variability from pixel to pixel makes the use of pixel-based classifiersobsolete. READ MORE
