Wireless capsule endoscopy is a new technology in the realm of telemedicine that has many advantages over the traditional endoscopy systems. Transmitted images should help diagnosis of diseases of the gastrointestinal tract. Two important technical challenges for the manufacturers of these capsules are power consumption and size of the circuitry. Also, the system must be fast enough for real-time processing of image or video data. To solve this problem, many hardware designs have been proposed for implementation of the image processing unit. In this paper we propose an architecture that could be used for the assessment of endoscopy images. The assessment allows avoidance of transmission of medically useless images. Hence, volume of data is reduced for more efficient transmission of images by the endoscopy capsule. This is done by color space conversion and moment calculation of images captured by the capsule. The inputs of the proposed architecture are RGB image frames and the outputs are images with converted colors and calculated image moments. Experimental results indicate that the proposed architecture has low complexity and is appropriate for a real-time application.
无线胶囊内镜是远程医疗领域的一项新技术,与传统内镜系统相比具有诸多优势。传输的图像应有助于胃肠道疾病的诊断。对于这些胶囊的制造商而言,两个重要的技术挑战是功耗和电路尺寸。此外,该系统必须足够快以实时处理图像或视频数据。为了解决这个问题,已经提出了许多硬件设计来实现图像处理单元。在本文中,我们提出了一种可用于评估内镜图像的架构。这种评估可以避免传输医学上无用的图像。因此,通过减少数据量,内镜胶囊能够更高效地传输图像。这是通过对胶囊捕获的图像进行颜色空间转换和矩计算来实现的。所提出架构的输入是RGB图像帧,输出是颜色转换后的图像和计算出的图像矩。实验结果表明,所提出的架构具有低复杂度,适用于实时应用。
