本文提出了一种从彩色灰度图像中恢复彩色图像的系统。从运行成本、数据量和安全性等多个角度来看，可逆彩色到灰度算法在实际应用中是一种有效的技术。大多数传统的算法只适用于封闭的计算机世界中的电子灰度图像，而不是通过打印和捕获过程来处理真实世界的材料。我们挑战这个重要的问题，并构建了一个彩色图像恢复系统，从一个单色相机捕获的打印灰度图像。图像的几何形状、灰度级和分辨率在打印和捕获过程中发生变化。提出了一种利用灰度图像上的标定图案来恢复彩色图像的方法。实验结果表明，该系统可以动态地从单色相机下设置的打印灰度图像恢复彩色图像。
This paper develops a color image recovery system from a color-embedded gray image. A reversible color-to-gray algorithm is an effective technique from several viewpoints such as running cost, data quantity, and security in practical applications. Most of the conventional algorithms work only on electronic gray images in the closed computer world, and do not work on real-world materials through the printing and capturing processes. We challenge this important problem and construct a color image recovery system from a printed gray image captured by a monochrome camera. The image geometry, gray level, and resolution change through the printing and capturing processes. We present a solution method to recovery color image by using a calibration pattern attached to the gray image. Experimental results show that the proposed system can dynamically recover a color image from a printed gray image that is set under a monochrome camera.
