The primary regulator of the humanoid system is the human brain. A brain tumor develops when brain cells grow and divide abnormally, and brain cancer develops when brain tumors continue to grow. Computer vision is important in the field of human health because it eliminates the need for human judgment to produce correct results. The most dependable and secure imaging techniques for magnetic resonance imaging (MRI) are CT scans, X-rays, and MRI scans. MRI can identify minute items.

Our paper will concentrate on the many methods for using brain MRI to find brain cancer. The bilateral filter (BF) was used in this study's pre-processing to get rid of any noise that was present.

Keywords—Brain tumor, Magnetic resonance imaging, Adaptive Bilateral Filter, Convolution Neural Network.
