Study of Image Fusion using Discrete wavelet and Multiwavelet Transform

Kusum Rani, Reecha Sharma

Image fusion is processes of combining complementary information from a set of input images. The resultant fused image give large and reliable information. In this paper we study about Discrete wavelet and Discrete Multiwavelet and there use in image fusion. Discrete wavelet transform (DWT) technique is used for multi Resolution fusion. Multi Resolution fusion uses wavelet transform at multi scale for the representation of the source images. Multiwavelets are extension of scalar wavelets, and have many advantages over scalar wavelets. Multiwavelet analysis can provide a more absolute image analysis than wavelet multiresolution analysis.In this paper DWT and DMWT are qualitatively compaired with each other
