In Recent days Semi supervised image segmentation techniques play a noteworthy role in image processing.Semi supervised image segmentation needs both labeled data and unlabeled data.It means that a Small amount of human assistance or Prior information is given during clustering process.This paper discusses an enhanced semi supervised image segmentation method from labeled image.It uses both a background selection marker and fore ground object selection marker separately.The EM (Expectation Maximization) algorithm is used for clustering along with must link constraints.The proposed method is applied for natural images using MATLAB 7. Thus the proposed method extracts Object of Interest (OOI) from OONI (Object of Not Interest) efficiently and the experimental results are compared with Standard K Means and EM Algorithm also.The results show that the proposed system gives better results than the other two methods.It may also be suitable for object extraction from natural images and medical image analysis.
