Abstract
Brain tumor segmentation methodology is based on Convolutional Neural Networks (CNN), by
exploring into small 3x3 kernels. The employment of small kernels permits coming up with a
deeper architecture, besides having a positive impact against over fitting, given the less variety
of masses within the network and also investigating on the utilization of intensity normalization
as a pre-processing step, which is not common in Convolution Neural Network based
segmentation methods, and well-tried in conjunction with information augmentation to be
intolerably in effect for neoplasm segmentation in magnetic resonance imaging pictures.
