  • Comparison of the VARDIG algorithm on two parallel processors

    Creator:
    Roof, Becky Jane
    Abstract:
    The specific objectives of this project are to compare the Sequent and the transputer to determine the speed of both and find out which is easiest for programming in parallel. The results are graphs showing relative and real time speedup versus number of processors and conclusions based on those graphs....

  • Mathematical morphology : a case study of linear shift-invariant filter implementation

    Creator:
    Eo, Jin-Woo
    Abstract:
    Morphological filters have shown good performance in various image processing applications. Furthermore, their algorithms are easy to implement in special architectures, with the exception that linear filtering cannot be implemented in many of these cases. In this study, a new architecture and corresponding algorithm, capable of realizing linear shiftinvariant filters,...

  • Hardware implementation of color transforms in the analog domain for wood surface analysis

    Creator:
    Abhyankar, Rajendra
    Abstract:
    This thesis discusses the hardware implementations of certain linear and non-linear color space transforms thought to be useful in the analysis of wood surfaces for defect detection. The developmental system's color image digitizer contains 5 bits per color while the input signal contains considerably greater resolution. This often degrades the...

  • Overcoming the singularity problem in digital image restoration

    Creator:
    Osta, Ahmad M.
    Abstract:
    A recorded image is a degraded version of an original image. The process of removing the degradations is called restoration. Two types of degradations are considered in this thesis: namely, linear motion and defocused lens blurrings. Using the direct deconvolution technique to restore blurred images is impossible if the blurring...

  • 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...

  • 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...

  • 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,...

  • 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...

  • Processing of laser interferometric signals for small displacement measurements

    Creator:
    Peng, Gwo-sheng
    Abstract:
    Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...
