To improve the accuracy of tumor identification, it is necessary to develop a reliable automated diagnostic method. In order to precisely categorize brain tumors, researchers developed a variety of segmentation algorithms. Segmentation of brain images is generally recognized as one of the most challenging tasks in medical image processing. In this article, a novel automated detection and classification method was proposed. The proposed approach consisted of many phases, including pre-processing MRI images, segmenting images, extracting features, and classifying images. During the pre-processing portion of an MRI scan, an adaptive filter was utilized to eliminate background noise. For feature extraction, the local-binary grey level co-occurrence matrix (LBGLCM) was used, and for image segmentation, enhanced fuzzy c-means clustering (EFCMC) was used. After extracting the scan features, we used a deep learning model to classify MRI images into two groups: glioma and normal. The classifications were created using a convolutional recurrent neural network (CRNN). The proposed technique improved brain image classification from a defined input dataset. MRI scans from the REMBRANDT dataset, which consisted of 620 testing and 2480 training sets, were used for the research. The data demonstrate that the newly proposed method outperformed its predecessors. The proposed CRNN strategy was compared against BP, U-Net, and ResNet, which are three of the most prevalent classification approaches currently being used. For brain tumor classification, the proposed system outcomes were 98.17% accuracy, 91.34% specificity, and 98.79% sensitivity.
为了提高肿瘤识别的准确性,有必要开发一种可靠的自动诊断方法。为了精确分类脑肿瘤,研究人员开发了多种分割算法。脑图像分割通常被认为是医学图像处理中最具挑战性的任务之一。在本文中,提出了一种新颖的自动检测和分类方法。所提出的方法包括多个阶段,包括对MRI图像进行预处理、分割图像、提取特征和对图像进行分类。在MRI扫描的预处理部分,使用自适应滤波器消除背景噪声。对于特征提取,使用局部二进制灰度共生矩阵(LBGLCM),对于图像分割,使用增强模糊c均值聚类(EFCMC)。提取扫描特征后,我们使用深度学习模型将MRI图像分为两组:胶质瘤和正常。分类使用卷积循环神经网络(CRNN)创建。所提出的技术改进了从定义的输入数据集中对脑图像的分类。研究使用了REMBRANDT数据集中的MRI扫描,该数据集由620个测试集和2480个训练集组成。数据表明,新提出的方法优于其前身。将所提出的CRNN策略与目前使用的三种最流行的分类方法BP、U-Net和ResNet进行了比较。对于脑肿瘤分类,所提出系统的结果是准确率为98.17%,特异性为91.34%,灵敏度为98.79%。
