| 摘 要： | 介绍了一种基于小波变换的图像融合算法,它利用像素邻域平均梯度作为选择依据,对小波变换后的高频系数进行选择,再逆变换完成图像融合.通过对红外热图与可见光图像的融合实验表明:基于小波系数区域平均梯度的融合能使红外热图更加清晰,融合的图像光谱变异性较小,图像效果较好.

| Abstract: | An image fusion algorithm based on wavelet transform is introduced, it chooses the high-frequency coefficient after wavelet transform according to average gradient of local area of resolution, and then complete the image fusion by reverse transform. The experiment results of fusion of visible image and infrared image demonstrate the algorithm can enhance infrared image definition, reduce fusion image variability, and increase fusion image definition. |
