  The idea of combining multiple image modalities to provide a single, enhanced
image is well established different fusion methods have been proposed in
literature. This paper is based on image fusion using laplacian pyramid and
wavelet transform method. Images of same size are used for experimentation.
Images used for the experimentation are standard images and averaging filter is
used of equal weights in original images to burl. Performance of image fusion
technique is measured by mean square error, normalized absolute error and peak
signal to noise ratio. From the performance analysis it has been observed that
MSE is decreased in case of both the methods where as PSNR increased, NAE
decreased in case of laplacian pyramid where as constant for wavelet transform
method.
