The document presents a method for brain tumor segmentation and detection using F-transform. There are two main stages: detection and segmentation. In detection, asymmetry between the left and right hemispheres of the brain is analyzed to detect abnormalities. In segmentation, F-transform is used for edge detection followed by morphological operations to extract the tumor region. The method was able to accurately segment and detect brain tumors in MRI images and showed improved speed over other techniques.
