Edge Preserving Image Fusion Based on Contourlet Transform

Abstract: Abstract. Image fusion is an emerging area of research having a number of applications in medical imaging, remote sensing, satellite imaging, target tracking, concealed weapon detection and biometrics. In the present work, we have proposed a new edge preserving image fusion method based on contourlet transform. As contourlet transform has high directionality and anisotropy, it gives better image representation than wavelet transforms. Also contourlet transform represents salient features of images such as edge… Show more

“…Though, the disadvantage is the spectral degradation which reduces the contrast levels in the fused image and hence could affect negatively the classification results [43,44]. The transform domain fusion comprises multi-resolution [45], wavelet transform [46,47], Laplacian and Gaussian pyramid [48], Bandelet Transform, Contourlet [49,50], and Curvelet [51,52]. The Fourier transform of the entire image into the frequency domain overcomes the limitations of the spatial domain methods.…”

“…Novel multi-scale analysis approaches are proposed including rideglet transform [14], curvelets transform [15], contourlet transform [16], non-subsampled contourlet transform (NSCT) [17] and shearlets transform [18]. Contourlet transform is widely utilized in the edge preserving image fusion domain because of preventing the edge aliasing [19,20]. Paper also illustrates its lack of shift-invariance property, which can lead to obvious Gibbs phenomenon [20].…”
