基于改进型WBCT的多光谱图像融合方法
Multi-spectral Image Fusion Method Based on Improved WBCT
摘要
Abstract
Aiming at multi-spectral image fusion problem, this paper proposes an improved Wavelet-based Contourlet Transform(WBCT) by adopting lifting wavelet transform instead of traditional wavelet transform. Multi-scale decomposition is performed on source images through the improved method to get high-frequency and low-frequency component, which are then processed by different fusion rules and the fused coefficients are obtained. And the inverse improved WBCT is utilized to obtain fused image. Experimental results show that compared with Contourlet tra"sform and lifting wavelet transform, improved method has better integration effect.关键词
