    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  3. 3. Video Signal Processing: Compression Segmentation and Tracking

    University dissertation from Chalmers University of Technology

    Author : Andrew Backhouse; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informationsteknik; Information technology; Signalbehandling; Signal processing;

    Abstract : 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. READ MORE

  4. 4. Machine-Printed and Handwritten Ethiopic Script Recognition

    University dissertation from Chalmers University of Technology

    Author : Yaregal Assabie; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Bildanalys; Image analysis; Signalbehandling; Signal processing; Systemteknik; Systems engineering; Ethiopic Character Recognition; Amharic Word Recognition; OCR; Handwriting Recognition; HMM; Direction Field Tensor; Structure Tensor;

    Abstract : A written language is represented by using machine-printed or handwritten symbols called characters. For automatic recognition of written languages, handwritten script can be captured offline (by a scanner) and online (by electronic digital devices), whereas machine-printed text is captured offline.

  5. 5. Robust Visual Object Tracking mean shift, particle filters and point features

    University dissertation from Chalmers University of Technology

    Author : Zulfiqar H. Khan; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; Bildanalys; Image analysis; Datorteknik; Computer engineering; Signalbehandling; Signal processing; visual object tracking; mean shift; SIFT; SURF; RANSAC; PF; MSEPF;

    Abstract : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state of the object and how it changes over time, in recursive video frames. READ MORE
