The dice coefficient is the measure used to determine the similarity of two data sets. It compares the pixel to the expected image and ground truth pixel values.

Abstract
Cancer is one of the most lethal diseases in the world. A brain tumor is a form of cancer that develops in the brain's glial cells. Magnetic resonance imaging (MRI) is a prominent imaging tool for detecting brain tumors. It includes four different modalities that neurologists use to determine the location and kind of tumor. The suggested approach uses a 2D U-Net model to separate the brain tumors sub regions. To prevent excessive preprocessing and GPU utilization, the authors utilize the patching approach to partition the picture slices into distinct patches in this study. Second, they leverage the squeeze and excitation blocks to more effectively map low-level features to high-level features than a basic U-Net. The suggested technique yields DICE scores of 0.85, 0.87, and 0.90 for the three tumor categories of enhancing tumor, whole tumor, and tumor core, respectively. The results outperform the most recent approaches, including the major papers from the Brats 2019 competition.
