Efficient deep learning models for brain tumor detection with segmentation and data augmentation techniques

Abstract

Brain tumor is an acute cancerous disease that results from abnormal and uncontrollable cell division. Brain tumors are classified via biopsy, which is not normally done before the brain ultimate surgery. Recent advances and improvements in deep learning (DL) models helped the health industry in getting accurate diseases diagnosis. This article concentrates on the classification of magnetic resonance (MR) images.The objective is to differentiate between glioma tumors, meningioma tumors, pituitary tumors, and normal cases. Four deep convolutional neural networks are considered and compared in this article. These networks are inceptionresnetv2, inceptionv3, transfer learning, and BRAIN-TUMOR-net. A transfer-learning strategy is considered to enhance the performance of pre-trained models and save the time of training. The used dataset is the brain tumor magnetic resonance imaging dataset. It contains four classes including 826 MR images for glioma tumor, 822 MR images for meningioma tumor, 827 MR images for pituitary tumor, and 835 MR images for normal cases. Due to the limited number of images, we use the augmentation strategy to enlarge the size of the dataset. 75% of the data are considered for training and the other 25% are considered for testing. Segmentation of the classified results is performed. Simulation resultsprove that the DL model from scratch obtains the highest performance with the augmented data. In addition, a new practical implementation is presented for the proposed models.

The impact of image augmentation techniques of MRI patients in deep transfer learning networks for brain tumor detection

“…Shoaib et al [20] by using four deep convolutional neural networks, including BRAIN-TUMOR-net, transfer learning, inceptionv3, and inceptionresnetv2, attempted to identify between normal cases versus pituitary tumors, meningioma tumors, and glioma tumors. They employ the augmentation approach in order to increase the dataset size due to the small number of photos.…”

An enhanced pattern detection and segmentation of brain tumors in MRI images using deep learning technique

“…They used gliomas, meningioma, pituitary, and normal brain MRI images for brain tumor categorization. The model was trained on 75% of the images, and 25% were used for validation (Shoaib et al, 2022 ). However, gaps (Nida-Ur-Rehman et al, 2017 ; Irmak, 2021 ; Maqsood et al, 2022 ; Shoaib et al, 2022 ) still need to be filled while addressing brain tumor segmentation.…”
