Cancer is one of the top causes of mortality, and it arises when cells in the body grow abnormally, like in the case of breast cancer. For people all around the world, it has now become a huge issue and a threat to their safety and wellbeing. Breast cancer is one of the major causes of death among females all over the globe, and it is particularly prevalent in the United States. It is possible to diagnose breast cancer using a variety of imaging modalities including mammography, computerized tomography (CT), magnetic resonance imaging (MRI), ultrasound, and biopsies, among others. To analyze the picture, a histopathology study (biopsy) is often performed, which assists in the diagnosis of breast cancer. The goal of this study is to develop improved strategies for various CAD phases that will play a critical role in minimizing the variability gap between and among observers. It created an automatic segmentation approach that is then followed by self-driven post-processing activities to successfully identify the Fourier Transform based Segmentation in the CAD system to improve its performance. When compared to existing techniques, the proposed segmentation technique has several advantages: spatial information is incorporated, there is no need to set any initial parameters beforehand, it is independent of magnification, it automatically determines the inputs for morphological operations to enhance segmented images so that pathologists can analyze the image with greater clarity, and it is fast. Extensive tests were conducted to determine the most effective feature extraction techniques and to investigate how textural, morphological, and graph characteristics impact the accuracy of categorization classification. In addition, a classification strategy for breast cancer detection has been developed that is based on weighted feature selection and uses an upgraded version of the Genetic Algorithm in conjunction with a Convolutional Neural Network Classifier. The practical application of the suggested improved segmentation and classification algorithms for the CAD framework may reduce the number of incorrect diagnoses and increase the accuracy of classification. So, it may serve as a second opinion tool for pathologists and aid in the early detection of diseases.
癌症是导致死亡的主要原因之一,当身体内的细胞异常生长时,就会发生癌症,例如乳腺癌。对全世界的人们来说,癌症现在已经成为一个巨大的问题,对他们的安全和健康构成了威胁。乳腺癌是全球女性死亡的主要原因之一,尤其是在美国。有许多成像方式可以用于诊断乳腺癌,包括乳房 X 线摄影、计算机断层扫描(CT)、磁共振成像(MRI)、超声以及活检等等。为了分析图像,通常会进行组织病理学研究(活检),这有助于诊断乳腺癌。该研究的目的是为各种 CAD 阶段开发改进的策略,这将在缩小观察者之间的差异方面发挥关键作用。它创建了一种自动分割方法,然后进行自主的后处理活动,以成功识别 CAD 系统中基于傅里叶变换的分割,从而提高其性能。与现有技术相比,所提出的分割技术具有以下几个优点:可以合并空间信息,无需事先设置任何初始参数,它与放大倍数无关,可以自动确定形态操作的输入,以增强分割图像,从而使病理学家可以更清晰地分析图像,而且速度很快。进行了广泛的测试,以确定最有效的特征提取技术,并研究纹理、形态和图形特征如何影响分类分类的准确性。此外,还开发了一种基于加权特征选择的乳腺癌检测分类策略,并结合改进后的遗传算法和卷积神经网络分类器来实现。建议的改进分割和分类算法在 CAD 框架中的实际应用可能会减少错误诊断的数量并提高分类的准确性。因此,它可以作为病理学家的第二个意见工具,并有助于疾病的早期发现。
