    A new weighted guided image filter (WGIF) avoids halo artifacts common in local filtering methods. This edge-preserving smoothing technique enhances image quality for tasks like detail enhancement and haze removal.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Digital Signal Processing

    Background:

    • Local filtering methods for edge-preserving smoothing often produce undesirable halo artifacts.
    • Existing techniques struggle to balance smoothing with artifact reduction.

    Purpose of the Study:

    • Introduce a novel weighted guided image filter (WGIF) to overcome the limitations of existing edge-preserving smoothing techniques.
    • Address halo artifacts while maintaining computational efficiency.

    Main Methods:

    • Developed the weighted guided image filter (WGIF) by integrating an edge-aware weighting mechanism into the guided image filter (GIF).
    • Analyzed the computational complexity, achieving O(N) for an image with N pixels.
    • Applied WGIF to single image detail enhancement, haze removal, and exposure fusion.

    Main Results:

    • The WGIF effectively reduces or eliminates halo artifacts, a common issue in local filtering.
    • Achieved superior visual quality in enhanced images, haze-free images, and fused images.
    • Demonstrated that WGIF maintains efficiency with a negligible increase in running time compared to GIF.

    Conclusions:

    • The proposed WGIF offers a robust solution for edge-preserving image smoothing, mitigating halo artifacts.
    • WGIF combines the benefits of global and local smoothing filters, providing enhanced image quality.
    • The method is computationally efficient and applicable to various image enhancement tasks.
