Wavelet-based image fusion involves merging complementary information from multi-sensor data to create a new composite image, primarily for applications like target surveillance and recognition. This paper proposes an image fusion method utilizing wavelet transform and analyzes the fusion results of visible-light and infrared images. The implementation demonstrates excellent fusion effects with clear distinction between targets and backgrounds, while maintaining smooth edge transitions. The method shows promising application prospects through its algorithmic efficiency and robustness.

Detailed Documentation

Wavelet-based image fusion refers to the integration of complementary data from multiple sensors to generate a new composite image, enhancing capabilities for target monitoring, recognition, and other applications. This paper presents an image fusion methodology grounded in wavelet transform, with detailed analysis of fusion outcomes between visible-light and infrared images. The implementation typically involves decomposing source images using Discrete Wavelet Transform (DWT) across multiple resolution levels, followed by fusion rule application (e.g., maximum coefficient selection or weighted averaging) in wavelet domains. Experimental results confirm outstanding fusion performance: targets and backgrounds exhibit sharp differentiation while edge transitions remain natural without abrupt artifacts. Consequently, this approach demonstrates broad application potential and contributes significantly to advancing image fusion technology through its computationally efficient multi-resolution analysis framework.
