Abstract: All information is conveyed through images. Images play a vital role in every field that makes the problem easier to understand. Image processing techniques are most widely used in medical imaging to identify the affected area through x-ray, MRI, CT scan. Medical image processing is used to detect and identify the inner most portions of the human body. Due to several abnormalities in human body such as visualization, heart diseases, cancer, brain tumor, blood clotting which can be identified through image processing techniques. Using spatial filtering algorithm, we can filter the brain tumor of an image. The algorithm is been used on different images of the brain detected with tumor and filter the desired output.
Keywords: Pre-processing, MRI, spatial filtering, segmentation, tumour detection.
