Research paper thumbnail of Automatic Watershed Segmentation and Comparison between Pixel Scan Method and Order-Invariant Algorithm for Image Segmentation

International Conference on Computational Intelligence and Multimedia Applications (ICCIMA 2007), 2007

The technologies for M2M solutions are also analyzed. This paper is mainly concerned with automatic protection of unman level crossing and tracking of opposite train in the railway network. We also propose a preventive algorithm in stated areas especially in unman level crossing. The provided generic software framework in unman level crossing allows systems to function effective and efficiently. Main scope of this paper is that an alarm signal is directly given to both control centre and train itself. The alert has been given by means of both light and audio medium.

Research paper thumbnail of Segmentation of MR Images using Active Contours: Methods, Challenges and Applications

In recent years, Active contours have been widely studied and applied in medical image analysis. ... more In recent years, Active contours have been widely studied and applied in medical image analysis. Active contours combine underlying information with high-level prior knowledge to achieve automatic segmentation for complex objects. Their applications include edge detection, segmentation of objects, shape modelling and object boundary tracking. This paper presents the development process of active contour models and describes the classical parametric active contour models, geometric active contour models, and new hybrid active contour models based on curve evolution and energy minimization techniques. It also discusses challenges and applications of active contour models in medical image segmentation.
