Abstract

An additive wavelet fusion method based on local wavelet energy to fuse multi-focus images is presented in this paper. First, multi-resolution decomposition of source images is obtained by wavelet transform. Second, the corresponding sub-band images by using different rules are fused, that is, the method based on average is used in low frequency components while high frequency components are fused by an additive wavelet method based on local energy. Finally, the fused image is obtained by inverse wavelet transform. Entropy and spatial frequency are used to evaluate the image fusion results. The new method is tested by two sets of multi-focus images. The experimental results show that the proposed method can achieve a better fusion performance. Moreover the proposed method is effective, applicable and adaptive for different image data. The influence of the block size of wavelet coefficient and two different wavelet transforms (Mallat's and 'a trous' wavelet) on the fusion results is also discussed, which is of great value for research and experiment in this field.
