在本文中,我们提出了一种将 RGB 彩色图像转换为灰度图像的新算法。我们建议使用非线性降维技术将高维颜色向量映射到低维颜色向量。这种方法概括了高维图像的梯度域操作。我们的实验表明,所提出的算法产生了有竞争力的结果,并在质量和速度之间达到了良好的折衷。
In this paper we present a new algorithm to transform an RGB color image to a grayscale image. We propose using nonlinear dimension reduction techniques to map higher dimensional color vectors to lower dimensional ones. This approach generalizes the gradient domain manipulation for high dimensional images. Our experiments show that the proposed algorithm generates competitive results and reaches a good compromise between quality and speed.
