Recent facts and figures published in various studies in the US show that approximately 27,510 new cases of gastric infections are diagnosed. Furthermore, it has also been reported that the mortality rate is quite high in diagnosed cases. The early detection of these infections can save precious human lives. As the manual process of these infections is time-consuming and expensive, therefore automated Computer-Aided Diagnosis (CAD) systems are required which helps the endoscopy specialists in their clinics. Generally, an automated method of gastric infection detections using Wireless Capsule Endoscopy (WCE) is comprised of the following steps such as contrast preprocessing, feature extraction, segmentation of infected regions, and classification into their relevant categories. These steps consist of various challenges that reduce the detection and recognition accuracy as well as increase the computation time. In this review, authors have focused on the importance of WCE in medical imaging, the role of endoscopy for bleeding-related infections, and the scope of endoscopy. Further, the general steps and highlighting the importance of each step have been presented. A detailed discussion and future directions have been provided at the end.
最近在美国的各项研究中公布的事实和数据表明，大约有 27510 例新的胃部感染病例被诊断出来。此外，据报道，确诊病例的死亡率相当高。这些感染的早期检测可以挽救宝贵的生命。由于这些感染的人工处理过程既耗时又昂贵，因此需要自动化的计算机辅助诊断 (CAD) 系统，以帮助内窥镜专家在其诊所中进行诊断。一般来说，使用无线胶囊内窥镜 (WCE) 进行胃部感染检测的自动化方法包括以下步骤，如对比预处理、特征提取、感染区域的分割以及分类到相关类别。这些步骤包含各种挑战，降低了检测和识别的准确性，并增加了计算时间。在本次综述中，作者关注了 WCE 在医学成像中的重要性、内窥镜在出血相关感染中的作用以及内窥镜的应用范围。此外，还介绍了一般步骤，并强调了每个步骤的重要性。最后提供了详细的讨论和未来的方向。
