摘要: 将平面图像转换成立体图像很有意义。Hou等人(2002)提出了一种平面图像立体化方法，称为Hou方法。在这个方法中Hou等人使用随机变量等参数控制转换过程，但没有讨论这些参数对立体效果的影响。该文利用Hou方法在标准的计算机监视器上对含有心理深度暗示的平面图像进行了立体化，给出了评价转换后的立体效果的定量指标，并讨论了各参数对立体效果的影响。实验结果表明：当随机变量矩阵中的每一个随机变量都服从同一种均匀分布时，随机变量的取值对立体效果没有多大的影响；当监视器屏幕与观察者的距离为一个合适的值(例如1m)时，图像子块的个数取不同的值对立体效果没有多大的影响。Abstract: It is significant to convert planar images into stereo images. Hou et al. (2002) presented a method to realize the function and it is called Hou method. In this method, the parameters such as random variables are used to control the procedure, but the stereo effect that the parameters take on had not been discussed. Using Hou method, the planar image with psychological depth cue is converted into stereo on standard computer monitor. Quantitative criterions to evaluate the stereo effect after conversion are given. And further more, the stereo effect that the random variables take on is discussed. The results of the experiment show that, when every random variable in matrix has the same uniform distribution, different values of these random variables take little effect on stereo effect; when the distance between the monitor screen and the observer is a well chosen value (e.g. 1m), the number of the sub-block images takes little effect on stereo effect.
