Abstract :
Image fusion is procedure of combination of the numerous images into particular image which comprise improved depiction of the sight and provides enhanced quality of fused image than source images. Image fusion provides a superior significance in defence, military affairs, civilian sector and medical area. This review article delivers a literature evaluation on the image fusion methods such as simple average, select minimum and maximum, principle component analysis, discrete wavelet transform, discrete cosine transform, lift wavelet transform etc. Execution of image fusion techniques can be calculated by parameters like Peak Signal to Noise Ratio, root mean square error, entropy, standard deviation, spatial frequency and mutual information. This article also presents the comparison of all the techniques.
