Investigation of image processing algorithms for medical applications

Functional Magnetic Resonance Imaging (fMRI) is a neuroimaging non-invasive method that uses magnetic resonance imaging. It deals with the detection of brain areas, which are usually involved in work or an emotion. It is basically, a way to providing information by measuring brain activity. One of t...
