Feature extraction calculates features on the basis of which image can be easily classified as normal or abnormal one. The feature extraction is the procedure to represent raw image to make possible decision making such as pattern classification. Features will be extracted from the tumor regions from MRI images. Feature extraction involves reducing the amount of data required to describe a large set of data accurately. Features are used as inputs to classifiers that assign them to the class that they represent. The intention of feature extraction is to reduce the original data by measuring positive properties, or features, that discriminate one input sample from another sample. Following features are extracted.
