N2 - The traditional White Patch Retinex algorithm is based on the "global white spot assumption", which leads to issues such as noise robustness, illumination estimation bias, and detail loss. To address these issues, this paper proposes a Dynamic Adaptive White Patch Retinex algorithm, named DAWPR, which introduces the Sobel operator to calculate the gradient amplitude of the image as a measure of image complexity. A mapping model is Constructed between gradient values and window size to form a dynamic window size adjustment mechanism for effectively solving the problem of light adaptability in power aerial images. The experimental results demonstrate that DAWPR has significant advantages in preserving details, enhancing clarity, and improving contrast.
