Generally the segmentation refers, the partitioning of an image into smaller regions to identify or locate the region of
abnormality. Even though image segmentation is the challenging task in medical applications, due to contrary image,
local observations of an image, noise image, non uniform texture of the images and so on. Many techniques are available
for image segmentation, but still it requires to introduce an efficient, fast medical image segmentation methods. This
research article introduces an efficient image segmentation method based on K means clustering integrated with
a spatial Fuzzy C means clustering algorithms. The suggested technique combines the advantages of the two methods.
K means segmentation requires minimum computation time, but spatial Fuzzy C means provides high accuracy for
image segmentation. The performance of the proposed method is evaluated in terms of accuracy, PSNR and processing
time. It also provides good implementation results for MRI brain image segmentation with high accuracy and minimal
execution time. After completing the segmentation the of abnormal part of the input MRI brain image, it is compulsory
to classify the image is normal or abnormal. There are many classifiers like a self organizing map, Back propagation
algorithm, support vector machine etc., The algorithm helps to classify the abnormalities like benign or malignant brain
tumour in case of MRI brain image. The abnormality is detected based on the extracted features from an input image.
Discrete wavelet transform helps to find the hidden information from the MRI brain image. The extracted features are
trained by Back Propagation Algorithm to classify the abnormalities of MRI brain image.
