论文摘要
无线胶囊内窥镜（WCE）于2001年作为观察整个胃肠道（GI）的关键方法之一，通常是小肠。它已用于检测胃肠道中的疾病。内窥镜图像分析仍然是一个必需的领域，存在许多开放问题。由于该成像系统的性质，它产生的许多图像的质量是不可接受的，这导致了一些问题，可以预测医生和计算机辅助诊断。在本文中，提出了一种新型技术来提高WCE捕获的图像的质量。更具体地说，它增强了亮度，对比度并保留颜色信息，同时降低了其计算复杂性。此外，PSNR和SSIM的实验结果证实，该方法中的错误率接近地面并且可以忽略不计。此外，提出的方法将强度限制的平均局部熵（IRMLE）提高了22％，颜色增强因子（CEF）提高了10％，并且可以有效地保持图像的轻度。与制作方法相比，我们方法的性能具有更好的视觉质量和客观评估。
Wireless Capsule Endoscopy (WCE) presented in 2001 as one of the key approaches to observe the entire gastrointestinal (GI) tract, generally the small bowels. It has been used to detect diseases in the gastrointestinal tract. Endoscopic image analysis is still a required field with many open problems. The quality of many images it produced is rather unacceptable due to the nature of this imaging system, which causes some issues to prognosticate by physicians and computer-aided diagnosis. In this paper, a novel technique is proposed to improve the quality of images captured by the WCE. More specifically, it enhanced the brightness, contrast, and preserve the color information while reducing its computational complexity. Furthermore, the experimental results of PSNR and SSIM confirm that the error rate in this method is near to the ground and negligible. Moreover, the proposed method improves intensity restricted average local entropy (IRMLE) by 22%, color enhancement factor (CEF) by 10%, and can keep the lightness of image effectively. The performances of our method have better visual quality and objective assessments in compare to the state-of-art methods.
