Denoising, skull stripping, segmentation, feature extraction, and classification are five important processes in this paper's development of a brain tumor classification model. The brain tumor image will be imposed first using the entropy-based trilateral filter to de-noising and this image is imposed to skull stripping by means of morphological partition and Otsu thresholding. Adaptive contrast limited fuzzy adaptive histogram equalization (CLFAHE) is also used in the segmentation process. The gray-level co-occurrence matrix (GLCM) characteristics are derived from the segmented image. The collected GLCM features are used in a hybrid classifier that combines the neural network (NN) and deep belief network (DBN) ideas. As an innovation, the hidden neurons of the two classifiers are modified ideally to improve the prediction model's accuracy. The hidden neurons are optimized using a unique hybrid optimization technique known as lion with dragonfly separation update (L-DSU), which integrates the approaches from both DA and LA. Finally, the suggested model's performance is compared to that of the standard models concerning certain performance measures.
去噪、颅骨剥离、分割、特征提取和分类是本文开发脑肿瘤分类模型的五个重要过程。首先使用基于熵的三边滤波器对脑肿瘤图像进行去噪处理,然后通过形态分割和 Otsu 阈值处理对颅骨进行剥离。在分割过程中还使用了自适应对比度受限模糊自适应直方图均衡化(CLFAHE)。从分割后的图像中提取灰度共生矩阵(GLCM)特征。收集的 GLCM 特征用于结合神经网络(NN)和深度置信网络(DBN)思想的混合分类器。作为一项创新,两个分类器的隐藏神经元经过理想的修改,以提高预测模型的准确性。使用一种独特的混合优化技术——狮子与蜻蜓分离更新(L-DSU)对隐藏神经元进行优化,该技术整合了 DA 和 LA 的方法。最后,根据某些性能指标,将所提出的模型的性能与标准模型进行比较。
