摘要
针对θ调制多光谱照相技术,提出了一种基于小波变换的图像融合及假彩色化新方法,其特点是使用改进的加权平均法融合可见光波段解码图像与红外图像的小波分解低频分量,以局部能量差为测度标准融合高频分量,将融合的图像在RGB空间合成假彩色图像.理论分析和实验结果表明该方法具有良好的融合性能和假彩色效果.
A new method is represented based on wavelet transform for image fusion and pseudo-coloring in multi-spectral photography with θ-modulation. Its features are as follows; The decoded image in visible band and infrared image＇s low frequency components are fused with improved Weighted Average Method, and the fusion image＇s high frequency components are obtained using local energy difference of two images as the fusion criterion. The fused images are synthesized into a pseudo-color in RGB color space. The theoretical analysis and experiment results show that with this method, good fusion performance and pseudo-color result can be achieved.
