A Brain MRI Segmentation Scheme Based on FCM Algorithm and MRF Models

Dangui Chen, Jia Tang

Abstract


Brain magnetic resonance imaging (MRI) has been a large number of applications in the clinic and accurate split of brain tissue’s structure. They can improve the reliability of the diagnosis of brain diseases and the effectiveness of treatment programs. For specializes in solving image fuzziness and uncertainty, fuzzy C-means clustering (FCM) algorithm is the most common used in brain MRI segmentation. But FCM is only utilized for the image gray information, without considering regional information. It would lead to its anti-noise performance. They often are improved in conjunction with regional information. Markov Random Field (MRF) models have taken full advantage of the image area information. It is prone to over-segmentation phenomenon combined with improved FCM and MRF. The improvements compared with the existed FCM and MRF method are combined a new adaptive weights combined with FCM and MRF algorithm for brain MRI segmentation. The algorithm has used image pixel area of the image neighborhood correlation. The adaptive joint field weight can improve existing combination weights. The combination of FCM and MRF is more reasonable than before. The experiment results are shown that the proposed algorithm is compared with FCM and the existed some FCM improvements of algorithm are greater noise immunity and higher segmentation accuracy.
