摘要

癌症患者可以从早期检测和诊断中获益。本研究提出了一种在超声图像中检测乳腺癌的机器视觉策略,并纠正了一些超声难题,如伪影、斑点噪声和模糊。在定量进化中,发现边缘保留标准优于混合各向异性扩散的标准。在深度 CNN 中插入了可学习的超分辨率(SR),以挖掘额外的可能信息。该特征与利用 Gabor 小波变换 (GWT) 和局部二进制模式 (LBP) 预先训练好的深度 CNN 模型相融合。用于创建这些推荐系统的机器学习(ML)技术需要类别分布均衡的数据,但现实世界中的大多数数据集都是不均衡的。不平衡的数据会迫使分类器专注于大多数类别,而忽略其他感兴趣的类别,从而降低任何分类模型的预测性能。在这项研究中,我们提出了一种生成对抗网络(GAN)策略来克服数据不平衡问题,并提高推荐系统的性能。我们使用标准数据来训练该模型,以确保高分辨率。在测试阶段,使用不同分辨率的通用数据来评估模型的性能。通过交叉验证发现,5 倍法可以成功消除过拟合问题。与目前的相关研究相比,这项建议的特征融合技术的准确率高达 99.48%,表现令人满意。最后,研究人员使用 U-Net 架构从 BC 超声波图像中提取癌症区域。

A novel automated system to detect breast cancer from ultrasound images using deep fused features with super resolution

Cancer patients can benefit from early detection and diagnosis. This study proposes a machine vision strategy for detecting breast cancer in ultrasound images and correcting several ultrasound difficulties such artifacts, speckle noise, and blurring. In quantitative evolution, edge preservation criteria were discovered to be superior to standard ones for hybrid anisotropic diffusion. A learnable super-resolution (SR) is inserted in the deep CNN to dig for extra possible information. The feature is fused with a pre-trained deep CNN model utilizing Gabor Wavelet Transform (GWT) and Local Binary Pattern (LBP). Machine learning (ML) techniques that are used to create these recommendation systems require well-balanced data in terms of class distribution, however most datasets in the real world are imbalanced. Imbalanced data forces a classifier to concentrate on the majority class while ignoring other classes of interest, lowering the predicted performance of any classification model. We propose a generative adversarial networks (GAN) strategy to overcome the data imbalance problem and improve the performance of recommendation systems in this research. Standard data is used to train this model, which assures a high level of resolution. In the testing phase, generalized data of varied resolution is used to evaluate the model's performance. It is discovered through cross-validation that a 5-fold method can successfully eliminate the overfitting problem. With an accuracy of 99.48 %, this suggested feature fusion technique indicates satisfactory performance when compared to current related works. Finally finding cancer region, researcher used U-Net architecture and extract cancer region from BC ultrasound images.
