1. Compare Accuracy of Alternative Methods for Sound Classification on Environmental Sounds of Similar Characteristics
University essay from Stockholms universitet/Statistiska institutionenAbstract : Artificial neural networks have in the last decade been a vital tool in image recognition, signal processing and speech recognition. Because of these networks' ability to be highly flexible, they suit a vast amount of different data. This flexible attribute is very sought for within the field of environmental sound classification.

3. Audio editing in the time-frequency domain using the Gabor Wavelet Transform
University essay from Centrum för bildanalysAbstract : Visualization, processing and editing of audio, directly on a time-frequency surface, is the scope of this thesis. More precisely the scalogram produced by a Gabor Wavelet transform is used, which is a powerful alternative to traditional techinques where the wave form is the main visual aid and editting is performed by parametric filters.

4. Multiview Face Detection Using Gabor Filter and Support Vector Machines
University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)Abstract : Face detection is a preprocessing step for face recognition algorithms. It is the localization of face/faces in an image or image sequence. Once the face(s) are localized, other computer vision algorithms such as face recognition, image compression, camera auto focusing etc are applied. READ MORE

5. Extraction and Application of Secondary Crease Information in Fingerprint Recognition Systems
University essay from Institutionen för teknik och naturvetenskapAbstract : 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. READ MORE
