Multi Model Image Registration and Fusion using Fast Discrete Contourlet Transform
نویسنده
چکیده
This paper proposes Transform Domain Fusion Rule (TDFR) via high pass modulation using Local Magnitude Ratio (LMR) in Fast Discrete Contour let Transform (FDCT) domain. Contour let transform method uses low resolution multispectral image and Cartosat-1 Panchromatic (PAN) of spatial resolution 2.5m is used as high resolution panchromatic image. This both images are up sampled in order to resize the image and registered using mutual information to parameterize and solve the correspondence problem in feature-based registration. This fusion rule generates as high resolution multispectral image at 2.5m spatial resolution with the help of Inverse Fast Discrete Contour let Transform increases the contrast of an image and thus gives sharper visual appearance. Different techniques are compared with this method such as Wavelet, Principal component analysis (PCA) and Curve let also tabulated. Keywords—Fast Discrete Contour let Transform (FDCT), Local Magnitude Ratio (LMR), Panchromatic (PAN), Principal Component Analysis (PCA),Transform Domain Fusion Rule (TDFR).

Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...

Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
