Image segmentation is the fundamental step for analysing the images and extracting data from them. It is already a widely researched field but it still provides the various challenges to the researches. This paper concentrates on basic methods which is used for image segmentation and classification. Image segmentation can be categorized as semiinteractive approach and fully automatic approach and the algorithms are developed either of these approaches. Image segmentation is like a step and it helps to influences the overall success to understand the image. This is the interesting application for testing the robustness of our approaches due to the complexity of the images and consequently we believe the algorithms will be suitable for many other real world applications. © 2016,International Journal of Pharmacy and Technology.
