Description

In many places DWT perform many roles of image processing. Magnetic Resonance Images are used in detecting and tracking brain tumors. Diagnostic brain MRI scans are usually performed by trained medical technologists who manually prescribe the position and orientation of a scanning volume. T2-weighted scans use a Spin Echo (SE) sequence, with long TE (Echo time) and long TR (repetition time). On a T2-weighted scan, water- and fluid-containing tissues are bright and fat containing tissues are dark. Medical image segmentation plays an important role in medical research field. In our paper, we propose image segmentation using hybrid model of both DWT and SELF-ORGANIZING MAP (SOM). Here this process gives better result than other segmentation algorithm.
