Classifying brain tumors from MRI scans is really tough because of all the noise and variation in the images and some tumors can look pretty similar. Even though deep learning models do a job they can miss important details if they are working alone and combining models can lead to repeating information. This research suggests using a combination of ResNet50 and VGG16 to get a look at the features of the tumors and then using PCA and mRMR to pick the most important ones. The goal is to tell apart four types of tumors which're glioma, meningioma, pituitary and no tumor using a multi-class SVM. This approach works well getting it right about 94.51 percent of the time. The good news is that it still works almost as well at 94.39 percent even when it is optimized to use fewer features and run faster which makes it a great tool, for helping doctors make decisions quickly and efficiently.
