基于相似度的图像变形效果的客观度量方法

Evaluation of Objective Effect Image Morphing Based on Similarity

给出了评价图像变形效果的新方法.首先,计算中间帧之间的相似度,由这些相似度值生成一条曲线;然后,在图像计算机动画领域首次提出图像变形真实感度的概念.它通过计算曲线与坐标轴,曲线插值点处的曲率和其他一些衡量标准得到.试验表明,它是一有效的度量图像变形效果的客观方法.

A novel method to evaluate image morphing reality is presented in this paper. First of all, similarity values among a series of frames of image morphing are calculated. Then they are interpolated to be a curve. Finally, image morphing reality degree （IMRD）is defined for the first time in the research field of image morphing by computing the area between the curve and one coordinate axis, curvatures of the curve at different points, and so on. Experimental results show IMRD is an effective method to evaluate objective effect of image morphing.
