基于小波变换的多分辨率图像融合技术的研究

Research of Multi-resolution Image Fusion Based on Wavelet Transform

本文提出了使用小波变换对多幅不同分辨率图像进行融合的方法。该方法对大分辨率图像进行正交小波变换分解图像,然后把逼近部分和小分辨率图像进行处理,得到处理的小波系数矩阵,对该矩阵进行反变换,得到一幅汲取两幅图像优势的融合图像。最后对该方法进行了实验,效果较好。

This paper presents a scheme of multi-resolution images using wavelet transform. The big image was decomposed to four sub-band images. The paper processed the low-low subimage and small image and got wavelet coefficients. Then the wavelet coefficients matrix was transformed inversely and got an fused image. At last, the paper verified this scheme and the result was better.
