Abstract: A novel method of Multi-exposure image fusion has been proposed in this paper. The images with varying exposures are fused to form a single image that is well exposed and contains the complete details of the scene with proper saturation and exposure. The proposed solution is based on the wavelet transform, in which the coefficients are fused on the basis of weight map that defines the contribution of that image in the resultant fused image. The weight map is based on the well exposedness, saturation and contrast metrics. The wavelet transform offers the multi-resolution blending to smooth the brightness variations in the fused image. The experimental results show that the proposed technique outperforms the previous approaches visually or subjectively
