As the quantity and significance of digital pictures in the medical industry continue to increase, Image Quality Assessment (IQA) has recently become a prevalent subject in the research community. Due to the wide range of distortions that Magnetic Resonance Images (MRI) can experience and the wide variety of information they contain, No-Reference Image Quality Assessment (NR-IQA) has always been a challenging study issue. In an attempt to address this issue, a novel hybrid Artificial Intelligence (AI) is proposed to analyze NR-IQ in massive MRI data. First, the features from the denoised MRI images are extracted using the gray level run length matrix (GLRLM) and EfficientNet B7 algorithm. Next, the Multi-Objective Reptile Search Algorithm (MRSA) was proposed for optimal feature vector selection. Then, the Self-evolving Deep Belief Fuzzy Neural network (SDBFN) algorithm was proposed for the effective NR-IQ analysis. The implementation of this research is executed using MATLAB software. The simulation results are compared with the various conventional methods in terms of correlation coefficient (PLCC), Root Mean Square Error (RMSE), Spearman Rank Order Correlation Coefficient (SROCC) and Kendall Rank Order Correlation Coefficient (KROCC), and Mean Absolute Error (MAE). In addition, our proposed approach yielded a quality number approximately we achieved significant 20% improvement than existing methods, with the PLCC parameter showing a notable increase compared to current techniques. Moreover, the RMSE number decreased by 12% when compared to existing methods. Graphical representations indicated mean MAE values of 0.02 for MRI knee dataset, 0.09 for MRI brain dataset, and 0.098 for MRI breast dataset, showcasing significantly lower MAE values compared to the baseline models.
随着医学领域中数字图像的数量和重要性不断增加,图像质量评估(IQA)最近已成为研究界的热门话题。由于磁共振图像(MRI)可能经历的失真范围广泛,并且包含的信息量多种多样,因此无参考图像质量评估(NR-IQA)一直是一个具有挑战性的研究问题。为了解决这个问题,提出了一种新的混合人工智能(AI)来分析大量 MRI 数据中的 NR-IQ。首先,使用灰度运行长度矩阵(GLRLM)和 EfficientNet B7 算法从去噪 MRI 图像中提取特征。接下来,提出了多目标爬行动物搜索算法(MRSA)来进行最佳特征向量选择。然后,提出了自进化深度信念模糊神经网络(SDBFN)算法来进行有效的 NR-IQ 分析。这项研究的实现是使用 MATLAB 软件完成的。根据相关系数(PLCC)、均方根误差(RMSE)、斯皮尔曼等级相关系数(SROCC)和肯德尔等级相关系数(KROCC)和平均绝对误差(MAE),将仿真结果与各种传统方法进行了比较。此外,与现有方法相比,我们提出的方法的质量数提高了约 20%,PLCC 参数与现有技术相比有显著提高。此外,与现有方法相比,RMSE 数量减少了 12%。图形表示显示 MRI 膝关节数据集的平均 MAE 值为 0.02,MRI 脑数据集的平均 MAE 值为 0.09,MRI 乳房数据集的平均 MAE 值为 0.098,与基线模型相比,MAE 值显著降低。
