An implementation of random walk algorithm to detect brain cancer in 2-d MRI

Brain is the control unit of a human body and is a highly specialized organ. It controls all the body functions. There are many diseases that could affect the normal functioning of brain and one of them is brain cancer. Some kinds of tumors are the prime cause of brain cancer. A brain tumor takes up space within the skull and can interfere with normal brain activity. It can increase pressure in the brain, shift the brain or push it against the skull, and/or invade and damage nerves and healthy brain tissue. Here random walk method is used to segment brain tissues for detection of cancerous cells.
