The nonsubsampled contourlet transform (NSCT) is one of the new geometrical image transform. This transform uses the nonsubsampled pyramids (NSP) and the nonsubsampled directional filter banks (NSDFB) to obtain a multiscale and multidirection decomposition of image. The NSCT is a shift-invariant transform contrast to the contourlet transform. The multiscale and multidirection image from NSCT is as...
The wavelet-based contourlet transform (WBCT) is a new directional transform. This transform uses the wavelet transform and the directional filter bank (DFB) to obtain a multiscale and multidirection decomposition of image. The wavelet transform and the DFB are non-redundant and perfect reconstruction. So the WBCT can be regarded as a non-redundant version of the contourlet transform. A new image...

A new method for infrared weak small target enhancement based on image fusion was presented. The structure of this method is two times fusion. In first fusion stage, the simple image fusion method is used to fuse the continuous frames. In second fusion stage, the multiscale decomposition method is used to decompose the result from first fusion stage and then fuse them. The fusion effect with different...
