Curvelet-Based Classification of Brain MRI Images
Abstract
Classification of brain MRI images is crucial in medical diagnosis. Automatic classification of these images helps in developing effective non-invasive procedures. In this paper, based on curvelet transform, a novel classification scheme of brain MRI images is proposed and a technique for extracting and selecting curvelet features is provided. To study the effectiveness of their use, the proposed features are employed into three different prediction algorithms, namely, K-nearest neighbours, support vector machine and decision tree. The method of K-fold stratified cross validation is used to assess the efficacy of the proposed classification solutions and the results are compared with those of various state-of-the-art classification schemes available in the literature. The experimental results demonstrate the superiority of the proposed decision tree classification scheme in terms of accuracy, generalization capability, and real-time reliability.
