Abstract

Current revelations in medical imaging have seen a slew of computer-aided diagnostic (CAD) tools for radiologists developed. Brain tumor classification is essential for radiologists to fully support and better interpret magnetic resonance imaging (MRI). In this work, we reported on new observations based on binary brain tumor categorization using HYBRID CNN-LSTM. Initially, the collected image is pre-processed and augmented using the following steps such as rotation, cropping, zooming, CLAHE (Contrast Limited Adaptive Histogram Equalization), and Random Rotation with panoramic stitching (RRPS). Then, a method called particle swarm optimization (PSO) is used to segment tumor regions in an MR image. After that, a hybrid CNN-LSTM classifier is applied to classify an image as a tumor or normal. In this proposed hybrid model, the CNN classifier is used for generating the feature map and the LSTM classifier is used for the classification process. The effectiveness of the proposed approach is analyzed based on the different metrics and outcomes compared to different methods.
