Different Wavelets are one of the efficient techniques used for fusing of two digital images. Coefficients obtained from various wavelet techniques are mathematically operated in many methods to obtain the corresponding coefficients for the fused image. In this paper, various such methods are compared using the entropy values. Higher the entropy, more information the output image holds and better the fusion method will be. Here, various mean combinations have been analyzed and best combination is predicated on the basis of entropy value.
