由於立體影片有著高品質的視覺效果，近幾年來，關於這方面的研究課題已受到許多的重視。然而，如何處理與儲存龐大的資料容量，為立體視訊應用的問題之一，本論文探討研究如何利用小波壓縮的技術來處理此問題。
立體視訊的視差之間會存在著許多相似的資料，本文利用動態補償技術的光流方法來計算找出這相似的資料。此光流方法是Horn and Schunck 所提出，最早在電腦視覺領域中，做為偵測物件移動的應用。在本文我們想利用光流方法來壓縮立體影片視差之間的相似資料，另外，在許多的研究可知，利用小波轉換的技術可以成功得到多尺度的模型。因此，我們應用小波轉換和零樹技術來壓縮光流。最後實驗結果證明在不同的狀況下，會得到不同的壓縮效果。

The topic of stereo video is getting more attention among these days due to its high quality of visual effect. However, the large volume of data is the problem of its application. The topic of this thesis is to investigate a compression technique by Wavelet compression on the stereo video data.
There is much similarity between the parallax videos. This similarity is obtained by a motion compensation technique: the optical flow computing. Optical flow proposed by Horn and Schunck was originally developed in the field of computer vision for the application of moving detection. In this thesis we apply the optical flow to compress the similarity information between the parallax stereo video. On the other hand, the Wavelet transformation has been proved to be a successful technique for multiscale modeling. We therefore applying the Wavelet transform combined with the zerotree compression to compress the fields of optical flow. Experimental results in this thesis have demonstrated different effects in different situations.
