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.
