A High-Quality Stereo Algorithm by Integrating Mask SEA and SEA-with-EVL.
Takashi Noguchi, Yuichi Ohta · 2002
There are an especially high number of false matching results in the object boundaries obtained by stereo matching.- In- general, these false results are caused by occlusion. In order to obtain high quality depth information, it is necessary to account for the effects of occlusion. "MaskSEA" and "SEA-with-EVL " were produced as a way of coping with occlusion. In MaskSEA, the quality of the depth information was enhanced by excluding the stereo pairs which were influenced by occlusion. In SEA-with-EVL, however, the quality was enhanced by limiting the illegal large evaluation value which were generated by the occlusion phenomenon. These two methods can be combined. In this paper, we propose a "MaskSEA-with-EVL " with the new evaluation method EVL applied to the usual MaskSEA. The experimental results showed that the quality of the depth information at the boundary area was better than the quality obtained when each technique was used independently. 1
