“…Asymmetry between histogram of squares was thought about in light of Bhattacharya coefficient and most topsy-turvy piece is relied upon to contain edema [10]. With same rule of mind symmetry, Shah, et al [28] introduced a quick bouncing box way to deal with identify tumor or edema. In this technique, normal dice coefficient accomplished are 0.57 and 0.52.…”

Medical imaging technology has revolutionized health care over the past three decades allowing doctors to detect, cure and improve patient outcomes. Medicinal imaging makes picture of the internal organs, parts, tissues and bones for therapeutic examination and research pur-poses. It can likewise be utilized to think about elements of a few organs. X-ray and CT scanner are the two greatest after-effect of headway of imaging methods supplanting 2D procedures. X-ray is the standout amongst the most critical pre-processing ventures in tumor discovery. Magnetic resonance imaging (MRI) is really an imaging procedure in the restorative field. It is utilized as a part of radiology for imagining interior structures of the body and furthermore how they work. X-ray gives you the 3D picture of the inside bits of the body which enables the specialist to dissect the infection or tumor effortlessly though old imaging procedures like x-beam imaging gives you 2D pictures. In this paper we are introducing distinctive systems for distinguishing, preparing restorative pictures.

Facing the condition that the inefficient training of traditional classifiers in the classification process of mammography, a classification method is proposed combining image processing and supervised learning. Firstly, the improved adaptive median filter enhances the image contrast. Then, according to the result of breast segmentation based on Gauss Mixture Model (GMM), this paper proposed a classification model based on Probabilistic Neural Network optimized (PNN) optimized by Gray Level Co-occurrence Matrix (GLCM) and Particle Swarm Optimization (PSO). The eigenvector extracted from the GLCM can be used as input to simplify the network structure. The smoothing factor optimized by PSO used to train the network can improve accuracy. The results in public mammographic patches database demonstrate that the model can classify the types of mammography effectively and perform better than the previous methods.

“…Zeng et al (2014) presented a three step methodology for image segmentation where they employed GMM for partitioning image into small groups followed by calculating the distance between GMM components through Kullback-Leibler (KL) divergence and finally similar GMM were merged through spectral clustering. Shah and Chauhan (2015) applied Hidden Markov Models (HMM) that used GMM for segmenting brain tumor from MRI images. They employed expectation maximization for achieving their objective and provided comparison with fuzzy c-mean based segmentation.…”

Segmentation is the fundamental step in most of digital image processing and computer vision based applications for feature extraction. The purpose of segmentation is to partition an image into foreground and background. Numerous segmentation algorithms have been proposed for the last four decades ranging from degraded images; high and low contrast images, indoor video, outdoor videos, videos with static background and dynamic backgrounds. This paper presents evaluation and comparison of segmentation techniques used for real-time moving objects through static and adaptive number of Gaussians. The techniques are tested for both indoor and outdoor scenes. The comparison is presented on the basis of qualitative results and computational complexities.
