IMAGE SEGMENTATION USING GAUSSIAN MIXTURE MODEL
Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we have learned Gaussian mixture model to the pixels of an image. The parameters of the model have estimated by EM-algorithm. In addition pixel labeling corresponded to each pixel of true image is made by Bayes rule. In fact, ...

Abstract: Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we used Gaussian mixture model to the pixels of an image. The parameters of the model were estimated by EM-algorithm. In addition pixel labeling corresponded to each pixel of true image was made by Bayes rule. In fact,...
متن کاملUnsupervised Texture Image Segmentation Using MRFEM Framework
Texture image analysis is one of the most important working realms of image processing in medical sciences and industry. Up to present, different approaches have been proposed for segmentation of texture images. In this paper, we offered unsupervised texture image segmentation based on Markov Random Field (MRF) model. First, we used Gabor filter with different parameters’ (frequency, orientatio...
متن کاملOpti-GVF Snake Model for Face Segmentation from Video Sequences
Face segmentation is one of the most important tasks in Model Based Video coding for Video Telephony and Video Conferencing applications. Since the face movement is usually different from the back ground movement, gradient of the optical flow field gives useful hints for the region of the image frame containing human face. In this work we have used a modified GVF-Snake (Gradient Vector Flow-Sna...
متن کاملDetection of Brain Tumor using GVF and Watershed Segmentation
the segmentation of brain tumor on MRI image is complicated and it is very important in medical field. If the segmentation done by expert it will be time consuming to overcome this problem researcher provided an alternative method for this. This is less time consuming in this paper a semi-automatic method is used for brain tumor segmentation by MRI images. This process involves preprocessing in...
