Abstract
3-D display technology is one of popular topics in recent years. In the process of generating 3-D visual perspective, depth map plays an important role in rebuilding the stereoscopic effect. So far, manually drawing the depth map is the mainstream in movie industry. However, it costs lots of money and time. Therefore, many automatic and semi-automatic depth estimation methods have been published in recent years.
In this thesis, a three-phase and semi-automatic system is proposed. First, the input image/frames are analyzed to extract the information of scene. Then absolute depth estimation and relative depth estimation are employed to generate depth map. The proposed system is applicable to both single image and image sequence. For sequence inputs, temporal coherence is obtained to make the depth maps between frames being smooth and continuous.
The experimental results show that this method can estimate depth successfully. The effectiveness of the proposed system also gives development for automatic depth estimation. With the improvement of segmentation algorithm, generating depth map automatically will come true in the future.
