An approach to detect tumour using boundary trace and image subtraction method

Neha Jain and Bhairvi Singh

Morphometric assessment of tumor cells is important in the prediction of biological behaviour of brain cancer. In order to mechanize the process, the computer-based system has to develop, which can recognize the boundary of the cells. Many methods were proposed for the boundary detection in the literature. However, there is no such reliable method which locates the exact boundary of tumor in human brain. In the paper, a boundary edge detection method is used and is based on gamma correction, pseudo Coloring and Laplace mask. After applying the suitable method, image subtraction is applied over it. The method enhances the sharpness of pixels and effectively distinguishes between the tumorous cell and non-tumorous cell from the MRI image background.
