Nowadays identification of brain tumor is a critical and challenging work in the research field. We describe the detection of brain tumor by using thresholding segmentation. Segmentation of brain tumor in MRI is developing research works. It is used to identify the tumor shape, size, and exact location. Our proposed system has three stages to detect the brain tumor in MRI. Thresholding technique is developed to detect the brain tumor in MRI. The first stage is to collection MRI data from the web database. The second stage for pre-processing and finally post-processing. The proposed system is less time consuming while compared to other techniques and the medical experts are also easily identify the exact tumor location.

Magnetic Resonance Image (MRI) brain images have an essential role in medical analysis and cancer identification .In this paper multi kernel SVM algorithm is used for MRI brain tumor detection. The proposed work is involving the following stages: image acquisition, image preprocessing, feature extraction and tumor classification. An automatic threshold selection region based segmentation method called Otsu is used for thresholding during preprocessing stage. SVM classification algorithm with four different kernels are used to determine the normal and abnormal images. SVM with quadratic kernel results in best classification accuracy of 86.5%.
