当设计具有高精度色彩再现的彩色视频系统时，需要良好的措施来评估包括色彩再现在内的图像质量。从图像采集到图像再现的整个成像系统中存在一些退化源。颜色随机噪声是主要的劣化之一，通常在图像捕获阶段添加。在本文中，我们研究了 S-CIELAB（空间 CIELAB）和 STCIELAB（时空 CIELAB）色差的性能，作为随机噪声降低的彩色电影的质量度量。在实验中，我们向三种静止图像和两种运动图像添加时空噪声，进行观察者评估实验，找到噪声刚好可以察觉的噪声水平。通过 CIELAB、S-CIELAB 和 ST-CIELAB 空间测量与人类观察者可察觉的噪声水平相对应的图像之间的色差。在本文中，我们报告了 S-CIELAB 和 ST-CIELAB 与 CIELAB 的性能比较。
When a color video system with highly accurate color reproduction is designed, a good measure is required for evaluating the image quality including the color reproduction. There are some degradation sources in a total imaging system from image acquisition to image reproduction. Color random noise is one of major degradations which is often added in image capture phase. In this paper, we investigate the performance of the S-CIELAB (spatial CIELAB) and STCIELAB (spatiotemporal CIELAB) color difference as a quality measure in color motion picture degraded by random noise. In the experiment, we added a spatiotemporal noise to three kinds of still images and two kinds of motion pictures, performed the observer evaluation experiment, and found the noise level at which the noise is just noticeable. Color differences between images which correspond to just noticeable noise level by human observers were measured by CIELAB, S-CIELAB and ST-CIELAB space. In this paper, we report the performance of S-CIELAB and ST-CIELAB compared to CIELAB.
