Edge Detection is an important tool in image processing. Proper identification of edges plays a very vital role in medical image analysis. Especially, medical decision support systems frequently demand the ability to identify and locate sharp discontinuities in an image for feature extraction and interpretation of image content. In the proposed work, a new algorithm based on mathematical morphology is used to perform edge detection on lung CT image impregnated with noise. The computational complexity of such a method is very less, making it possible to have real-time implementation of the proposed algorithm. The reconstruction of the original noisefree image enhances the versatility of the proposed algorithm.
