Where where hR, hF are the normalized gray level histograms of xRand xF, respectively. The joint gray level histogram ofxR and xF is denoted by hR,F, and L is the number of bins. xF and xR correspond to the fused and reference mental images, respectively. I(xRxF) indicates how much information the fused image xF conveys about the reference xR. Thus, higher the mutual information between xF and xR, in that location are more chances that xF resembles the ideal xR.D. Entropy (EN)-Entropy can be used to measure the difference between two source images and the fused image. The data of an image is a measure of information content. Entropy is the average number of bits which have a need of quantize the intensities in the image. It is represented as follows where p(g) is the chance of grey-level g , and the range of g is 0,.....,L-1.High information content of image would have high entropy. High entropy of fused image indicates that the it contains more information than the first im age sources.V. PROPOSED SOFTWARE DESIGNInteractive software is developed to do the reliable monitoring and management of Fusion process. The system software is made victimization MATLAB .We are taking two images image A and image B after the process of Counterlet transform. We get one output fused image. VI.CONCLUSIONWith this we conclude that contourlet turn can be used to fuse two dimensional images and represent them more efficiently, which makes the fused images more clear and more informative. Contourlet Transform overcomes the drawbacks of traditional chassis Fusion schemes by using ALM. The Experimental results using this technique of IF show that it can preserve more useful information in the fused image with higher spatial ... ....7, pp . 372-377( 2009) 12) Yi Yang ,Chongzhao Han ,Xin Kang and Deqiang Han An Overview on Pixel-Level I mage Fusion in Remote Sensing, Proceedings of the IEEE International Conference on Automation and Logistic,vol 6, no .4, pp .2339- 2344 feb (2007)13)image code, IEEE Transactions on Communications, vol. 31, pp. 532540, 1983.14) R.
