Abstract

Human brains are the most complex organs. There are a number of functions that this three-pound organ performs, including intelligence, interpreter of the senses, initiator of bodily movements, and controller of behaviour. In this paper, a novel ER-GAN model has been proposed for image inpainting (IIP) Brain MRI images. Initially, the brain MRI images are segmented using Attention V-Net. In the first GAN, Edge reconstruction Generative Adversarial Networks (EGAN) are used as edge generators able to hallucinate edges in missing regions based on the rest of the image’s edges and grayscale pixel intensities. Edge generation in brain MRI images involves leveraging these grayscale pixel intensities to detect boundaries between different brain tissues or structures. The varying intensities in MRI images often correspond to changes in tissue composition or boundaries between anatomical regions, making them valuable for edge detection and delineation. The second GAN uses the Region Reconstruction Generative Adversarial Network (RGAN) to fill in the missing regions by combining edge information from the missing regions and color and texture information from the surrounding regions. In experimental analysis, the Jaccard Index (JI) and Dice Index (DI) are obtained at 0.78 and 0.84 respectively. The proposed ER-GAN model reaches an overall accuracy of 99.25%, which is comparatively better than the existing techniques.

Abstract Image

通过基于边缘区域的深度生成对抗网络绘制脑磁共振图像
人类的大脑是最复杂的器官。这个三磅重的器官具有多种功能,包括智能、感官解释器、身体运动的启动器和行为控制器。本文提出了一种新颖的 ER-GAN 模型,用于对脑核磁共振成像图像进行图像着色 (IIP)。首先,使用注意力 V-Net 对大脑 MRI 图像进行分割。在第一个 GAN 中,边缘重构生成对抗网络(EGAN)被用作边缘生成器,能够根据图像的其他边缘和灰度像素强度在缺失区域生成边缘。脑部核磁共振成像图像中的边缘生成包括利用这些灰度像素强度来检测不同脑组织或结构之间的边界。核磁共振成像图像中的不同强度往往对应着组织成分的变化或解剖区域之间的边界,因此对边缘检测和划分非常有价值。第二个 GAN 使用区域重建生成对抗网络(RGAN),结合缺失区域的边缘信息和周围区域的颜色和纹理信息来填补缺失区域。在实验分析中,Jaccard 指数(JI)和 Dice 指数(DI)分别为 0.78 和 0.84。所提出的 ER-GAN 模型的总体准确率达到 99.25%,相对优于现有技术。
