Abstract: Brain tumour occurs when abnormal cells appear within the brain. Primary tumour starts with abnormal growth of brain cells whereas Secondary (Metastatic) tumour initiates as cancer in other parts of the body and spread to the brain through blood stream. In this paper, we propose a novel approach to detect tumour in magnetic resonance (MR) brain images. The proposed method uses improved incremental self organise mapping (I2SOM) to segment the brain image and to calculate asymmetry Zernike moments (ZMs), Pseudo-Zernike moments (PZMs) and orthogonal Fourier Mellin moments (OFMMs) are used. It omits the limitation of pre-determination of class of input data and the manual setting of appropriate threshold value. The effectiveness of the proposed method is analysed by doing experiments on 30 MR brain images with tumour and 30 normal MR brain images. It is observed that tumour detection is successfully realised for 30 MR brain images with tumour.
