摘要	Color information is ignored in most of the image quality assessment methods. Color information and luminance information are two important parts in color image. Loss of color information will result in the low consistency of the assessment results. Aiming to the problem, full-quaternion is defined in this paper. It is used to describe the structure information of a color image. The real part and imagery parts in full quaternion are used to perform the task. It differs from the traditional pure quaternion-based color image description method where the detail information in an image is enhanced by using the real part of a quaternion. To enhance the detail information in an image, local variance of luminance layer and the three color channels are taken as the real part and imagery parts respectively. On the basis of that, the structure similarity (SSIM) measure is studied and the quaternion-based structure similarity measure is used to perform color image structure comparison. Results from the experiments show that the proposed method combines detail information and color information of a color image. It can describe the structure information better than the traditional description methods. The quantitative results reveal that the performance of the full quaternion-based method is better than the pure quaternion-based method and many state-of-the-art methods. The values of Kendall rank correlation coefficient (KRCC), spearman rank correlation coefficient (SRCC) and root mean squared error (RMSE) are 0.692 9, 0.881 8 and 7.506, respectively, which proves that the performance of the proposed method is better than the other methods in the experiment.
