Abstract

Cerebrovascular diseases such as strokes seriously affect a person's life and good health. The diagnosis and treatment of stroke are significantly aided by the quantitative analysis of the brain using Magnetic Resonance Imaging (MRI) images. The prime intention of this research is to design an effective Hybrid Xception-ShuffleNet (HX-ShuffleNet) for detecting stroke disease. Initially, an MRI image is acquired from the database. Then, the acquired MRI image is fed into the image denoising module, where image denoising is performed using a median filter. Later, the stroke lesion segmentation is done based on the U-Net to isolate the stroke lesions from the entire image. After stroke lesion segmentation, image augmentation (random rotation, shifting, shearing, flipping) is done. Features are extracted using Dual-Tree-Fuzzy Local Binary Pattern (DT-FLBP), which combines Dual-Tree Complex Wavelet Transform (DTCWT), Fuzzy Local Binary Pattern (FLBP), and entropy. For stroke detection, HX-ShuffleNet, a fusion of Xception and ShuffleNet models, is used, achieving a True Positive Rate (TPR) of 0.928, accuracy of 0.935, True Negative Rate (TNR) of 0.929, Precision of 0.922, and F1-score of 0.928.
基于DT-FLBP和熵特征的MRI脑卒中检测混合深度学习框架
脑血管疾病如中风严重影响人的生活和身体健康。脑磁共振成像(MRI)图像的定量分析对中风的诊断和治疗有很大的帮助。本研究的主要目的是设计一种有效的混合异常- shufflenet (HX-ShuffleNet)用于检测中风疾病。首先,从数据库中获取MRI图像。然后,将获取的MRI图像送入图像去噪模块,其中使用中值滤波器进行图像去噪。然后,基于U-Net进行脑卒中病灶分割,将脑卒中病灶从整个图像中分离出来。在脑卒中病灶分割后,进行图像增强(随机旋转、移动、剪切、翻转)。采用双树复小波变换(DTCWT)、模糊局部二值模式(FLBP)和熵相结合的双树模糊局部二值模式(DT-FLBP)提取特征。脑卒中检测采用Xception和ShuffleNet模型融合的HX-ShuffleNet模型,其真阳性率(True Positive Rate, TPR)为0.928,准确率为0.935,真阴性率(True Negative Rate, TNR)为0.929,精度为0.922,f1评分为0.928。

期刊介绍: The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
