Underwater Image Enhancement Based on Dark Channel Theory

2017
The inaccurate estimation of underwater background light and distortion of scene color results in the lower quality of recovered underwater images. To address this problem, the paper proposes an enhancement algorithm for underwater images based on dark channel theory, which is expected to improve the clarity, contrast and color fidelity of underwater ...

Specular Reflection Separation Using Dark Channel Prior

2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013
We present a novel method to separate specular reflection from a single image. Separating an image into diffuse and specular components is an ill-posed problem due to lack of observations. Existing methods rely on a specular-free image to detect and estimate specularity, which however may confuse diffuse pixels with the same hue but a different ...

Dark channel based illumination invariant feature detection

2017 18th International Conference on Advanced Robotics (ICAR), 2017
This paper provides a novel feature detection method which utilizes illumination invariant space to achieve a high performance of robustness under the variating lighting conditions. Taking advantage of the dark channel prior knowledge, the proposed method builds three indicators to describe the illumination invariant components in the RGB color space ...

Jet Trajectory Recognition Based on Dark Channel Prior

2016
The automatic fire-fighting water cannon is an important device for fire extinguish. By identifying the jet trajectory, the closed-loop control of fire extinguishing process can be realized, which improves the quality and efficiency of the water cannon.
