Abstract: In this paper a comparative study on two methodologies namely Region Growing method and Zernike Moments were done. Normally the diagnosing of brain tumour is carried out by examining the Magnetic Resonance Imaging (MRI) scans. The detection of tumour from MRI Images was carried out independently by the two methodologies and the performance were compared based on two criterions: Root Mean Square Error (RMSE) and Time Complexity. The Results Analysis shows that brain tumour detection carried out by Zernike Moments method is having better performance than Region Growing method.
