  • Stochastic properties of morphological filters

    Creator:
    Zhu, Feihong
    Abstract:
    Most of the existing research on mathematical morphology is restricted to the deterministic case. This thesis addresses the void in the results on the stochastic properties of morphological filters. The primary results include analysis of the stochastic properties of morphological operations, such as dilation, erosion, closing and opening. Two unbiased...

  • Wavelet analysis as a signal processing method for multiresolution signal decomposition in natural resources applications

    Creator:
    Tu, De Yun
    Abstract:
    The purpose of this thesis is to apply the wavelet transform WT to multiresolution structures for analyzing the information content of images based on multiresolution signal decomposition of the wavelet representation. The advantage of the wavelet transform is the fact that it uses different building blocks than the Fourier's sines...

  • Restoration of quadratically distorted images

    Creator:
    Kwon, Tae-hwan
    Abstract:
    The problem of the restoration of quadratically distorted images is considered in this investigation, based upon the fact that images formed by partially coherent illuminations are related quadratically to the amplitude of the object. Two of the most important problems in image restoration are: 1) determining the degradation characteristics of...

  • Multi-variate morphological filtering with applications to color image processing

    Creator:
    Eo, Jin-woo
    Abstract:
    Mathematical morphology, developed in the early 1960's for single-component signals, has been applied to a number of image processing applications. This investigation examines the systematic extension of mathematical morphology to multi-variate signals. Two approaches are considered. The first approach, the extension of the theory of single-component morphological filters to multi-variate...

  • 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...

  • Content-based color image retrieval

    Creator:
    Varanguien de Villepin, Audrey
    Abstract:
    A fully automated method for content-based color image retrieval is developed to extract color and shape content of an image. A color segmentation algorithm based on the k-mean clustering algorithm is used and a saturated distance is proposed to discriminate between two color points in the HSV color space. The...

  • 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...

    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...
