AI Technical Summary
Technical Problem
In existing technologies, the fusion of color and near-infrared images may result in colors that deviate from the true colors and poor image quality, especially in smoggy environments where the fusion effect is not ideal.
Method used
By decomposing RGB and NIR images into detail and fundamental parts, fusing them using different weights in the radiation domain, and combining the luminance component based on infrared emission intensity, adjusting the color component, and suppressing the saturation effect in blurred areas, local alignment and iterative correction of the image are achieved.
Benefits of technology
It improves image detail, color fidelity, and reduces blur levels, resulting in higher-quality fused images.

Abstract
本申请涉及校正图像颜色。为场景捕获第一图像和第二图像，并将其融合成融合图像。所述第一图像和所述融合图像对应于颜色空间中的多个颜色通道。选择第一颜色通道作为锚通道。在分别对应于所述第一图像和所述融合图像的所述第一颜色通道的第一颜色信息项和第二颜色信息项之间确定锚比率，对于每个第二颜色通道，基于所述锚比率和所述第一图像对应的至少一个第三信息项来确定相应的校正颜色信息项。将所述融合图像的所述第一颜色通道的所述第二颜色信息项与所述第二颜色通道中的每一者的相应的所述校正颜色信息项组合以在色彩空间中形成最终图像。
