摘要：Image fusion is widely used term in different applications namely satellite imaging, remote sensing,multifocus imaging medical imaging, robotic vision and military applications. In this paper, multi-level image fusion isimplemented where fusion is performed in two stages. Firstly, Discrete Wavelet or Fast Discrete Curvelet transform isapplied on both source images and secondly image fusion is carried out with a spatial domain method like Averaging.Further, comparative analysis of fused image obtained from both Discrete Wavelet and Fast Discrete Curvelettransform is done which proves effective image fusion using proposed Curvelet transform than Wavelet transformthrough enhanced visual quality of fused image and by analysis of seven quality metrics parameters. The proposedmethod is very innovative which can be applied to medical and multifocus imaging applications in real time.
