Abstract: At present, the medical image processing is an important and development field. The various diagnosis of disease is CT, MRI and PET scanned image. These technologies are found to detect small defects in the human body. The main result of this paper, the earlier detection of brain tumor using Pre-processing techniques of median, bilateral and adaptive bilateral method was compared both filtering methods and proved the adaptive bilateral method is suitable method for MRI images. In Proposed, there are three main contributions are implemented in this filter method. (1)The extension of adaptive bilateral method to apply sub-bands of low frequency signal decomposed using wavelet transform. A wavelet threshold is combined with adaptive bilateral method to form an innovative structure in image de-noising method. It’s very efficient to eliminate noise in original noisy images. (2) First detected block boundary and texture regions discontinuities to adapt or control the parameters of spatial and intensity in bilateral filter. The adaptive method can improve the restored image quality in this test result compared with standard bilateral filter. (3) The improvements of fast bilateral method using the combination of Gaussian filter. I proposed the various image resolution of adaptive bilateral method was proved better results.
