1. 6. Performance monitoring on high-end general processing boards using hardware performance counters

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Gabor Andai; [2015]
   Nyckelord :;

   Sammanfattning : Most of the advanced microprocessors today incorporate on-chip hardware performance counters. These counters are capable to count various events in a non-invasive way, while executing real workloads. Events such as the number of instructions, memory accesses, cache and TLB misses are the most common ones that can be precisely measured. LÄS MER

3. 7. Time-frequency analysis for responses evoked by nociceptive and non-nociceptive stimuli based on EEG signals

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Juan Pablo Lagos Benitez; [2015]
   Nyckelord :ICA; artifact; pain; nociceptive; EEG; Technology and Engineering;

   Sammanfattning : In the pursuit of a system capable of measuring pain signals in humans we propose a method to differentiate those signals related to pain from those which are not. We performed a time-frequency analysis using the Gabor transform to have complete information about the spectrum and its behaviour through the time to study the main differences over the evoked potentials provoked by both nociceptive and somatosensory (non-nociceptive) stimulation.

4. 8. On the Short-Time Fourier Transform and Gabor Frames generated by B-splines

   Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

   Författare :Henrik Fredriksson; [2012]
   Nyckelord :short-time Fourier transform; time-frequency analysis; Gabor frames; B-splines;

   Sammanfattning : In this thesis we study the short-time Fourier transform. The short-time Fourier transform of a function f(x) is obtained by restricting our function to a short time segment and take the Fourier transform of this restriction. This method gives information locally of f in both time and frequency simultaneously. LÄS MER

5. 9. Selection, Analysis and Implementationof Image-based Feature Extraction Approaches for a Heterogenous, Modular and FPGA-based Architecture for Camera-based Driver Assistance Systems

   Master-uppsats, Högskolan i Halmstad/Intelligenta system (IS-lab)

   Författare :Peter Mühlfellner; [2011]
   Nyckelord :Object Detection; Feature Extraction; FPGA;

   Sammanfattning : We propose a scalable and fexible hardware architecture for the extraction of image features, used in conjunction with an attentional cascade classifier for appearance-based object detection. Individual feature processors calculate feature-values in parallel, using parameter-sets and image data that is distributed via BRAM buffers. LÄS MER

7. 10. Extraction and Application of Secondary Crease Information in Fingerprint Recognition Systems

   Uppsats för yrkesexamina på grundnivå, Institutionen för teknik och naturvetenskap

   Författare :Pontus Hymér; [2005]
   Nyckelord :Datorteknik; biometrics; fingerprint analysis; feature extraction; secondary creases; template aging; Gabor filter; pattern recognition; Hough transform; vector clustering; Datorteknik;

   Sammanfattning : This thesis states that cracks and scars, referred to as Secondary Creases, in fingerprint images can be used as means for aiding and complementing fingerprint recognition, especially in cases where there is not enough clear data to use traditional methods such as minutiae based or correlation techniques. A Gabor filter bank is used to extract areas with linear patterns, where after the Hough Transform is used to identify secondary creases in a r, theta space. LÄS MER
