摘要: RGB空间的高动态范围(HDR)彩色图像合成算法存在颜色失真和计算耗时的问题。为此,提出一种YUV空间的彩色图像HDR合成算法。利用多幅不同曝光度的普通数字图像,通过计算机高速运算对彩色图像进行HDR合成。实验结果表明,该算法的合成图像质量较高、计算速度较快。

Abstract: To overcome the color distortion and computational time-consuming problems with traditional RGB color space model, this paper proposes a method based on YUV color space model for creating High Dynamic Range(HDR) color images. This method uses a series of digital images with different exposure to generate a HDR color image. Experimental results show that the method is more efficient in computational speed and has better color image quality in comparison.
