Brain tumour (BT) is a dangerous neurological disorder produced by abnormal cell growth within the skull or brain. Nowadays, the death rate of people with BT is linearly growing. The finding of tumours at an early stage is crucial for giving treatment to patients, which improves the survival rate of patients. Hence, the BT classification (BTC) is done in this research using magnetic resonance imaging (MRI) images. In this research, the input MRI image is pre-processed using a non-local means (NLM) filter that denoises the input image. For attaining the effective classified result, the tumour area from the MRI image is segmented by the SegNet model. Furthermore, the BTC is accomplished by the LeNet model whose weight is optimized by the Golden Teacher Learning Optimization Algorithm (GTLO) such that the classified output produced by the LeNet model is Gliomas, Meningiomas, and Pituitary tumours. The experimental outcome displays that the GTLO-LeNet achieved an Accuracy of 0.896, Negative Predictive value (NPV) of 0.907, Positive Predictive value (PPV) of 0.821, True Negative Rate (TNR) of 0.880, and True Positive Rate (TPR) of 0.888.
脑肿瘤(BT)是一种由颅骨或脑内异常细胞生长引起的危险神经系统疾病。如今,脑肿瘤患者的死亡率呈线性增长。早期发现肿瘤对于为患者提供治疗至关重要,这可以提高患者的生存率。因此,本研究使用磁共振成像(MRI)图像进行脑肿瘤分类(BTC)。在本研究中,输入的MRI图像使用非局部均值(NLM)滤波器进行预处理,该滤波器对输入图像进行去噪。为了获得有效的分类结果,通过SegNet模型对MRI图像中的肿瘤区域进行分割。此外,BTC由LeNet模型完成,其权重通过黄金教师学习优化算法(GTLO)进行优化,使得LeNet模型产生的分类输出为胶质瘤、脑膜瘤和垂体瘤。实验结果表明,GTLO-LeNet的准确率为0.896,阴性预测值(NPV)为0.907,阳性预测值(PPV)为0.821,真阴性率(TNR)为0.880,真阳性率(TPR)为0.888。
