@article{(Open Science Index):https://publications.waset.org/pdf/91, title = {Active Contours with Prior Corner Detection}, author = {U.A.A. Niroshika and Ravinda G.N. Meegama}, country = {}, institution = {}, abstract = {Deformable active contours are widely used in computer vision and image processing applications for image segmentation, especially in biomedical image analysis. The active contour or “snake" deforms towards a target object by controlling the internal, image and constraint forces. However, if the contour initialized with a lesser number of control points, there is a high probability of surpassing the sharp corners of the object during deformation of the contour. In this paper, a new technique is proposed to construct the initial contour by incorporating prior knowledge of significant corners of the object detected using the Harris operator. This new reconstructed contour begins to deform, by attracting the snake towards the targeted object, without missing the corners. Experimental results with several synthetic images show the ability of the new technique to deal with sharp corners with a high accuracy than traditional methods.}, journal = {International Journal of Computer and Information Engineering}, volume = {6}, number = {2}, year = {2012}, pages = {231 - 235}, ee = {https://publications.waset.org/pdf/91}, url = {https://publications.waset.org/vol/62}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 62, 2012}, }
