研究目的
To compensate the contrast and color saturation of underwater images that suffer from low visibility and color cast due to light attenuation and scattering.
研究成果
The proposed method effectively enhances underwater images by improving contrast and color, outperforming state-of-the-art methods in both qualitative and quantitative evaluations.
研究不足
Not explicitly stated in the abstract or provided content, but potential limitations could include dependence on transmission estimation accuracy and applicability to various underwater conditions.
1：Experimental Design and Method Selection:
The method involves white balancing for color correction, multi-scale gradient domain contrast enhancement using edge-preserving decomposition, and color saturation compensation based on estimated transmission. It uses the atmospheric scattering model and weighted least squares for decomposition.
2：Sample Selection and Data Sources:
Underwater images are used, but specific sources or selection criteria are not detailed in the abstract or provided content.
3：List of Experimental Equipment and Materials:
Not specified in the provided content.
4：Experimental Procedures and Operational Workflow:
Steps include white balancing, decomposition into detail layers, transmission estimation, gradient enhancement, Poisson equation solving for reconstruction, and color saturation compensation.
5：Data Analysis Methods:
Qualitative evaluation by visual comparison and quantitative evaluation using blind measures (e.g., rate of new visible edges, percentage of saturated pixels, quality of contrast restoration) without reference images.
