Application of Contourlet Transform in Visible and Iinfrared Images Fusion

The Contourlet transform is a new image multiscale and multi-direction representation suitable for expressing the images with rich detail information and direction information.An infrared and visible image fusion algorithm based on the Contourlet transform is adopted to fuse the low frequency subband coefficients and the high frequency subband coefficients in all directions by suitable fusion rules.The fusion images are reconstructed by using the fusion coefficients.The experimental results show that this algorithm proposed above can get better fusion results than that of wavelet tranform image fusion.
