已有研究表明，视网膜显微手术中过度的白光照射可引起视网膜损伤。为了解决这个问题，人们可以用一种装置来照亮视网膜，这种装置可以在白光和破坏性较小的有限光谱光之间交替。然后，利用来自白光帧的信息，通过对有限光谱光帧重新上色，向外科医生展示一段全彩色视频。为了获得准确的彩色图像，同时降低光毒性，我们开发了一种新的算法来监测重新着色图像的质量，并确定白光何时可以被有限光谱光取代。我们在定性和定量上表明，与其他最先进的着色方案相比，我们的系统可以使用明显更小的光剂量提供可靠的图像。
It has been shown that excessive white light exposure during retinal microsurgery can induce retinal damage. To address this problem, one can illuminate the retina with a device that alternates between white, and less damaging limited-spectrum light. The surgeon is then presented with a fully colored video by recoloring the limited-spectrum light frames, using information from the white-light frames. To obtain accurately colored images, while reducing phototoxicity, we have developed a novel algorithm that monitors the quality of the recolored images and determines when white light may be substituted by limited-spectrum light. We show qualitatively and quantitatively that our system can provide reliable images using a significantly smaller light dose as compared to other state-of-the-art coloring schemes.
