Abstract

An algorithm for multi-focus image fusion using wavelet based contourlet transform was proposed for the transform is of multi-scale and multi-direction

and cycle spinning was introduced to decrease the shift-variance of the transform.The results show that this algorithm improves the visual effect of the fused image and decreases the RMSE value.
