Multi-View Depth Map Estimation With Cross-View Consistency

Motivation. Multi View Stereo (MVS) aims to establish 3D models from multiple calibrated images. Some works use region growing to estimate depth map per view, and then merge the results. They either only deal with reliable regions, or have difficulty in parallelizing. More crucially, due to the view-independent estimation, inconsistent outliers may exist and grow during propagation, producing u...

Harnessing Real - World Depth Edges with Multiflash

depth edges, are extremely useful 2.5D entities. The ability to localize and highlight depth discontinuities makes it possible to produce stylized photography and videos, which are useful in technical applications such as medical imaging and nonphotorealistic rendering (NPR). In addition, depth edges are important low-level features for many computer vision tasks, such as visual recognition. Fi...

Multi-view Depth Map Estimation Enhancing Temporal Consistency

In this paper, we propose a scheme for multiview depth map estimation to enhance temporal consistency. After we divide the center image into several segments, we estimate one depth value for each segment using 3-D warping and segment-based matching techniques. In the refinement process, we apply a segment-based belief propagation algorithm. In order to enhance temporal consistency and reliabili...

Depth and luminance edges attract.

The spatial resolution of disparity perception is poor compared to luminance perception, yet we do not notice that depth edges are more blurry than luminance edges. Is this because the two cues are combined by the visual system? Subjects judged the locations of depth-defined or luminance-defined edges, which were separated by up to 5.6 min of arc. The perceived edge location was a function of t...

Acquisition of sharp depth map from multiple cameras

We present a method to estimate a dense and sharp depth map using multiple cameras. A key issue for obtaining sharp depth map is how to overcome the harmful in uence of occlusion. Thus, we rst propose an occlusion-overcoming strategy which selectively use the depth information from multiple cameras. With a simple selection technique, we resolve the occlusion problem considerably at a slight sac...
