  • Motion detection algorithm using wavelet transform

    Creator:
    Lee, Jeongmin
    Abstract:
    This thesis presents an algorithm that estimates motion in image sequence using wavelet transform. The motion detection is performed under unfavorable conditions of background movement, change of brightness, and noise. The algorithm is tolerant to brightness changes, noise, and small movement in the background. The false alarm rate of motion...

  • 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...

  • Advanced image segmentation and data clustering concepts applied to digital image sequences featuring the response of biological materials to toxic agents

    Creator:
    Roussel, Nicolas
    Abstract:
    Image segmentation is the process by which an image is divided into number of regions. The regions are to be homogeneous with respect to some property. Definition of homogeneity depends mainly on the expected patterns of the objects of interest. The algorithms designed to perform these tasks can be divided...
