Title: | Active Contour Image Segmentation in Fisher Discriminant Spaces | Contributor(s): | Jayawardena, Ashoka (author); Kwan, Paul H (author) | Publication Date: | 2011 | Handle Link: | https://hdl.handle.net/1959.11/9752 | Abstract: | In this paper, we introduce an algorithm that is able to segment objects in natural images by using active contours. Active contours are used to regularize the segmentations. Our approach utilizes multiple feature spaces to capture as much information as possible, followed by projecting the multiple dimensional features space onto a single dimension to enable improved active contour evolution. We apply the Fisher Linear Discriminant Analysis (FLDA) to optimally calculate the projection vector while providing prior knowledge on number of clusters that are present on the image. Preliminary experiments confirm that the proposed algorithm is able to segment objects in natural images while optimizing contour smoothness and noises. | Publication Type: | Conference Publication | Conference Details: | IVCNZ 2011: 26th International Conference Image and Vision Computing New Zealand, Auckland, New Zealand, 29th November - 1st December, 2011 | Source of Publication: | Proceedings of the 2011 Image and Vision Computing New Zealand Conference (IVCNZ), p. 483-487 | Publisher: | Image and Vision Computing New Zealand | Place of Publication: | New Zealand | Fields of Research (FoR) 2008: | 080109 Pattern Recognition and Data Mining 080104 Computer Vision 080106 Image Processing |
