This research presents a novel deep learning framework for MRI-based brain tumour (BT) detection. The input brain MRI image is first acquired from the dataset. Once the images have been obtained, they are passed to an image preprocessing step where a median filter is used to eliminate noise and artefacts from the input image. The tumour-tumour region segmentation module receives the denoised image and it uses RP-Net to segment the BT region. Following that, in order to prevent overfitting, image augmentation is carried out utilizing methods including rotating, flipping, shifting, and colour augmentation. Later, the augmented image is forwarded to the feature extraction phase, wherein features like GLCM and proposed EGDP formulated by including entropy with GDP are extracted. Finally, based on the extracted features, BT detection is accomplished based on the proposed deep convolutional belief network (DCvB-Net), which is formulated using the deep convolutional neural network and deep belief network.The devised DCvB-Net for BT detection is investigated for its performance concerning true negative rate, accuracy, and true positive rate is established to have acquired values of 93%, 92.3%, and 93.1% correspondingly.
本研究提出了一种用于基于磁共振成像(MRI)的脑肿瘤(BT)检测的新型深度学习框架。首先从数据集中获取输入的脑部MRI图像。一旦获得图像,就将其传递到图像预处理步骤,在此步骤中使用中值滤波器从输入图像中消除噪声和伪影。肿瘤区域分割模块接收去噪后的图像,并使用RP-Net对BT区域进行分割。在此之后,为了防止过拟合,利用包括旋转、翻转、平移和颜色增强等方法进行图像增强。随后,将增强后的图像转发到特征提取阶段,在该阶段提取诸如灰度共生矩阵(GLCM)以及通过将熵与梯度方向概率(GDP)相结合而提出的EGDP等特征。最后,基于提取的特征,利用所提出的深度卷积置信网络(DCvB-Net)完成BT检测,该网络是使用深度卷积神经网络和深度置信网络构建的。针对所设计的用于BT检测的DCvB-Net,研究了其在真阴性率、准确率和真阳性率方面的性能,结果表明相应的值分别为93%、92.3%和93.1%。
