  • Automated Segmentation of Torn Frames using the Graph Cuts Technique 

    CORRIGAN, DAVID; HARTE, NAOMI; KOKARAM, ANIL CHRISTOPHER (2007)
    Film Tear is a form of degradation in archived film and is the physical ripping of the film material. Tear causes displacement of a region of the degraded frame and the loss of image data along the boundary of tear. In ...

  • Pathological motion detection for robust missing data treatment in degraded archived media 

    CORRIGAN, DAVID; HARTE, NAOMI; KOKARAM, ANIL CHRISTOPHER (2006)
    This paper outlines an algorithm to improve the robustness of missing data treatment to pathological motion (PM). PM can cause misdiagnosis of clean image data as missing data. The proposed algorithm uses a probabilistic ...

  • Robust Global Motion Estimation From Mpeg Streamswith a Gradient Based Refinement 

    CORRIGAN, DAVID; KOKARAM, ANIL CHRISTOPHER (IEEE, 2006)
    In this paper a new robust algorithm for global motion estimation from an MPEG stream is proposed. The approach is to use a hybrid of two previous global motion estimation algorithms in order to improve the accuracy and ...

  • Video Matting Using Motion Extended GrabCut. 

    CORRIGAN, DAVID; KOKARAM, ANIL CHRISTOPHER (IEEE, 2008)
    GrabCut is perhaps the most powerful semi-automatic algorithm for matting presented to date. In its existing form, it is not suitable for video object segmentation. This paper considers major extensions that make it ...

  • A wavelet-based Bayesian framework for 3D object segmentation in microscopy 

    RAMASWAMI, MANI; PAN, KANGYU; KOKARAM, ANIL; CORRIGAN, DAVID (2012)
    In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ...
