Abstract: In this paper, we present a saturation based image fusion technique for static scenes, which is aimed at generating high dynamic range images. The proposed methods can automatically fuse a set of images of the same stationary scene with different exposure levels that may include overexposed and underexposed images. The input images are blended into one output image automatically as a linear combination of the input images. The weighting factors for blending the images are determined by the saturation values of them. Larger saturation values indicate more vivid colors. Thus, we assign heavier weights to the pixels with larger saturation values, while lighter weights are applied to the pixels with smaller saturation values. Compared with existing methods, the fused images by the proposed method are satisfactory both visually and numerically at a low computational cost. The output images are also fairly free from the halo effect that is a common problem in many image fusion techniques
