一种图像morphing效果的客观度量方法

给出了评价图像morphing效果的新方法。该方法分两步: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morphing真实感度的概念(IMRD)。它通过计算曲线与坐标轴、曲线插值点处的曲率和其它一些衡量标准得到。试验表明,IMRD是一有效的度量图像morphing效果的客观方法,也是一种强有力的计算机动画的自动分析工具。

Approach to Evaluate Objective Effect of Image Morphing

A novel method to evaluate image morphing reality is presented in this paper.The algorithm includes two steps.First of all,similarity values among a series of frames of image morphing are calculated.Then similarity values can be 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 the objective effect of image morphing.And IMRD is a powerful tool for automatic analysis of computer animation.
