  • A Novel method to detecting lines on an image with high noise density

    Creator:
    Lin, Daniel
    Abstract:
    We developed an integration-based line detection algorithm. Existing line detection methods such as the Hough Transformation (HT) and its variants are insensitive to image noise. The reason is that HT finds lines by calculating the gradient of the image and assumes that the region where the gradient is the steepest...

  • A Novel Approach to Line Detection using Image Integration Method

    Creator:
    Lin, Daniel and Sun, Bo
    Abstract:
    - Collagen fibers are found in 25% of the whole body protein content. They are highly adhesive to cells and can be used as scaffold proteins that can promote cell growth and be used to capture cells. - In our lab, we use collagen to capture cancer cells in order...

  • Package inspection with a machine vision system

    Creator:
    Song, Zhao-ming
    Abstract:
    Machine Vision has been extensively applied in industry. This thesis project, which originated with a local food processor, applies a vision system to inspection of packages for cosmetric errors. The basic elements and theory of the machine vision system are introduced, and some image processing techniques, such as histogram analysis,...

  • A high-performance, low power and memory-efficient VLD for MPEG applications

    Creator:
    Zhang, Haowei
    Abstract:
    An extremely important area that has enabled or will enable many of the digital video services and applications such as VideoCD, DVD, DVC, HDTV, video conferencing, and DSS is digital video compression. The great success of digital video compression is mainly because of two factors. The state of the art...

  • Motion-based MPEG video summarization

    Creator:
    Colle, Olivier
    Abstract:
    A new, fully automated summarization algorithm of MPEG compressed videos is designed to address the challenge of content based video retrieval. This algorithm segments the MPEG stream motion vector magnitudes using a seed growing region technique. Following the spatial segmentation of each frame, an intra-frame class-merging operation is performed. The...

  • High resolution digital imaging of bacterial cells

    Creator:
    Siebold, William A.
    Abstract:
    The most abundant clone found in ribosomal RNA clone libraries obtained from the world's oceans belongs to the SAR11 phylogenetic group of environmental marine bacteria. Imaging and counting SAR11 bacterial cells in situ has been an important research objective for the past decade. This objective has been especially challenging due...

  • On-line lumber quality control technique using image processing

    Creator:
    Aslam, Fatima
    Abstract:
    Product quality control is the back bone for an efficient process control system. By monitoring the size of the board cut in a sawmill, performance of the production system can be controlled. Feedback from the quality control system is used to evaluate the status of the production system and also...

  • Object highlighting : real-time boundary detection using a Bayesian network

    Creator:
    Jia, Jin
    Abstract:
    Image segmentation continues to be a fundamental problem in computer vision and image understanding. In this thesis, we present a Bayesian network that we use for object boundary detection in which the MPE (most probable explanation) before any evidence can produce multiple non-overlapping, non-self-intersecting closed contours and the MPE with...

  • Demosaicking of color images by means of conditional random fields

    Creator:
    Kelm, Bernd Michael
    Abstract:
    Modern digital still cameras are equipped with just a single CCD for color image acquisition. Since only one spectral band can be recorded in each pixel, a mosaic of red, green and blue color filters is placed in front of the chip. The process of subsequently calculating a full color...
