A brain tumour is an abnormal mass of tissue. Brain tumours vary in size, from tiny to large. Moreover, they display variations in location, shape, and size, which add complexity to their detection. The accurate delineation of tumour regions poses a challenge due to their irregular boundaries. In this research, these issues are overcome by introducing the DTDO-ZFNet for detection of brain tumour. The input Magnetic Resonance Imaging (MRI) image is fed to the pre-processing stage. Tumour areas are segmented by utilizing SegNet in which the factors of SegNet are biased using DTDO. The image augmentation is carried out using eminent techniques, such as geometric transformation and colour space transformation. Here, features such as GIST descriptor, PCA-NGIST, statistical feature and Haralick features, SLBT feature, and CNN features are extricated. Finally, the categorization of the tumour is accomplished based on ZFNet, which is trained by utilizing DTDO. The devised DTDO is a consolidation of DTBO and CDDO. The comparison of proposed DTDO-ZFNet with the existing methods, which results in highest accuracy of 0.944, a positive predictive value (PPV) of 0.936, a true positive rate (TPR) of 0.939, a negative predictive value (NPV) of 0.937, and a minimal false-negative rate (FNR) of 0.061%.
脑肿瘤是一种异常的组织团块。脑肿瘤的大小不一,从微小到巨大。此外,它们在位置、形状和大小上都存在差异,这增加了它们检测的复杂性。由于肿瘤边界不规则,因此准确描绘肿瘤区域是一项挑战。在这项研究中,通过引入 DTDO-ZFNet 来检测脑肿瘤,克服了这些问题。输入的磁共振成像(MRI)图像被送入预处理阶段。利用 SegNet 对肿瘤区域进行分割,其中 SegNet 的因素使用 DTDO 进行了偏向处理。使用著名的技术(如几何变换和颜色空间变换)进行图像增强。在此,提取了 GIST 描述符、PCA-NGIST、统计特征和 Haralick 特征、SLBT 特征和 CNN 特征等特征。最后,基于 ZFNet 对肿瘤进行分类,该网络是利用 DTDO 进行训练的。所提出的 DTDO 是 DTBO 和 CDDO 的结合。将所提出的 DTDO-ZFNet 与现有方法进行比较,结果准确率最高为 0.944,阳性预测值(PPV)为 0.936,真阳性率(TPR)为 0.939,阴性预测值(NPV)为 0.937,最小假阴性率(FNR)为 0.061%。
