Brain Tumor Classification using MRI Image -A Survey

The leading cause of cancer related mortality in both kids and adults is brain tumor. Through the examination of the abnormalities of the tumor's tissues and cells, a tumor may be divided into many stages. The acute risk of tumor growth and spread is provided by this stage. Biopsy can be used to assess the tumor grade. It should be mentioned that tumor grading differs from cancer stage classification. Due to their high complexity and wide variation, brain tumor types are particularly difficult to diagnose with great accuracy. This survey starts with the review of 25 papers on brain tumor classification. The varied models used in the papers are analyzed, which includes methods for segmentation, classification and optimization. The analysis on varied metrics is analyzed and their maximal performances are also examined. Finally, chronological review is performed along with existing challenges.
