3. 2. Models and Algorithms - with applications to vehicle tracking and frequency estimation

   Författare :Joakim Gunnarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; subspace methods; radar detections; Automotive; F-ESPRIT.; vehicle tracking; frequency estimation;

   Sammanfattning : This thesis considers two different research problems; one concerned with the issue of tracking vehicles and one related to estimating frequencies in harmonic signals. The vehicle-tracking problem is addressed from the perspective of an automotive-safety application, which seeks to monitor the course of surrounding road users with the objective to make decisions regarding if, how and when to intervene.

4. 3. Singular Value Computations for Toeplitz Matrices and Subspace Tracking

   Författare :Eva Lundström; Henk van der Vorst; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis addresses the problem of computing the largest singular values and corresponding singular vectors of a Toeplitz matrix. These are often requested in signal processing and system identification to extract the signal from the noise. LÄS MER

5. 4. On Speech-to-Text Alignment, Phonetic Labeling, and Recursive Signal Processing

   Författare :Åke Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phonetic labeling; recursive algorithms; adaptive algorithms; speech-to-text alignment; dynamic programming; time-varying systems; subspace tracking; time-alignment; parameter estimation; time-warping;

   Sammanfattning : Speech data-bases are an important issue in the study of speech communication. In particular, time-aligned and phonetically labeled speech data-bases are useful during the design of applications such as speech recognizers. The time-alignment and labeling of the speech data is traditionally done manually. LÄS MER

7. 5. Video Signal Processing: Compression Segmentation and Tracking

   Författare :Andrew Backhouse; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis considers three separate research problems within the field of video processing.The first is concerned with segmenting an image, the second with tracking an object and the third with the communication of video across an unreliable network.Segmentation is an application-specific problem.
