Magnetic Resonance Imaging can be helpful in detecting brain tumor. It has advantages over procedures like Computed Tomography scan as it does not involve use of ionizing radiation due to which exposure of a person to such risks and related side effects can be prevented. Whatever be the technique of the imaging process, the one with the maximum accuracy must be preferred. Detection of brain tumor occurs in various stages like pre-processing, segmentation, feature extraction and classifier. For this to happen, k-mean segmentation approach is applied. Gray Level Co-Occurrence Matrix and Discrete Wavelet Transform are helpful in extraction of the tumor feature. Two types of classifiers are used for classification namely Support Vector Machine and Hidden Markov Model. Then the comparison is done based on performance parameters like sensitivity, specificity and accuracy. After calculating the results, the values of performance parameters are compared. The proposed technique has been found to perform well in terms of accuracy as compared to previous technique.
