Brain tumor is a perilous disease which causes brain damage. So detection and classification of brain tumor in early stage is necessary. Brain tumors can be basically categorized into normal, malignant or benign categories. There are two types of tumors- primary or secondary. Primary brain tumors originate in human brain and develop from growth of brain cells, membranes, nerve cells and glands. Secondary brain tumor originates in one part of the body and spreads into the brain or other part of the body. In the proposed work MRI brain images is converted into grayscale. Then the image is preprocessed using median filter for removing noises. Compute the standard deviation and by using canny edge detection, boundaries can be detected. Morphological operations such as dilation and erosion are applied for removing the unwanted disturbances after that tumor area is identified.

The proposed algorithm shows an effective method for segmentation of the brain tumors from the 2D MRI images. Detect presence of brain tumor based on thresholding method. Experimental results on data sets show that the proposed method performed automatic detection of brain tumor from mri scans. It also find the area of the tumor portion, minimizing the computational procedure, minimize the manual interaction.
