Shape-Based Depth Map Coding

2009 Fifth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2009
Three-dimensional Television (3DTV) system based on Depth-Image-Based Rendering(DIBR) has won popular recognition of researchers. Since the depth information is closely related with the rendering of viewed pixels, the quality of coding has a direct impact on the later effect of the three-dimensional(3D) video, of which the existence of cloud noise and ...

Colorization of Depth Map via Disentanglement

2020
Vision perception is one of the most important components for a computer or robot to understand the surrounding scene and achieve autonomous applications. However, most of the vision models are based on the RGB sensors, which in general are vulnerable to the insufficient lighting condition.

As-planar-as-possible depth map estimation

Computer Vision and Image Understanding, 2019
Abstract We propose an approach to compute dense disparity maps that takes the characteristics of man-made environments into account. The key contribution is to generate a piecewise planar disparity map while preventing the oversimplification problem in non-planar regions.

Rendering antialiased shadows with depth maps

Proceedings of the 14th annual conference on Computer graphics and interactive techniques, 1987
We present a solution to the aliasing problem for shadow algorithms that use depth maps. The solution is based on a new filtering technique called percentage closer filtering. In addition to antialiasing, the improved algorithm provides soft shadow boundaries that resemble penumbrae.

Mapping Local Image Deformations into Depth

2005
The paper presents a 2 frame structure-from-motion algorithm that operates by mapping local changes (image deformations) into estimates of time-to-collision (TTC). For constant velocity motion of the camera in a stationary scene, time-to-collision amounts to coarse depth data – useful for navigation and qualitative scene understanding.

Visualization of Depth Maps

1992
Coordinate systems are presented for fast 3-D transformations of complex surfaces, such as the depth maps produced by a laser camera or by a viewing algorithm. It is shown that these coordinate systems are natural for calculation on depth maps and correspond to a differential geometry approach of the problem.
