| 摘 要： | 由于采用色差方式度量视觉色度阈值,不能直接与色调和饱和度参数对应,限制了与色度图的接轨以及视觉相关方法的进一步研究,为此作者依据电视学色度信号的定义,通过产生色度信号模长与相角变化的测试图像,依据JND思路,分别观察这些不同模长和相角的测试图像,获取与色调和饱和度相关的视觉阈值,确定与色度视觉相关的图像质量评价方法.实验给出了与色调和饱和度相关的视觉阈值,验证了方案的可行性和有效性.

| Abstract: | Due to the adoption of color difference method to measure visiual threshold,the result could not correspond with hue and saturation parameters directly,which restricted its integratation with chromatic diagram and further research related to vision.According to the definition of chrominance signal,we researched the test images of different chrominance signal module and phase angle,based on the idea of JND,obtained the vision threshold value of hue and saturation,and defined a new criterion and method of image quality assessment related to chrominance vision by the generated various chrominance signal module and phase angle.The vision threshold value of hue and saturation experimentally validated the feasibility and effectiveness of our method. |
