研究目的
Investigating the use of full quaternions and wavelet transform for color image fusion to enhance detail information and improve fusion performance.
研究成果
The proposed method using full quaternions and wavelet transform for image fusion provides higher information entropy and average gradient, indicating better retention of image details and higher image clarity. Future work is needed to further study the method.
研究不足
The study is a simple experiment and analysis to evaluate the proposed mechanism, indicating that more work is necessary to study the method further.
1：Experimental Design and Method Selection:
The study uses full quaternions to describe image structure and performs image fusion via quaternion transform. The classical framework is applied for fusion, with color wavelet information expressed by quaternion wavelet.
2：Sample Selection and Data Sources:
Two types of source images are used for experiments, with a four-level wavelet decomposition based assessment method to assess the images.
3：List of Experimental Equipment and Materials:
The simulation program was written using Matlab R2013a.
4：3a.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The process involves expressing source images by quaternions, setting parameters, dealing with high-frequency and low-frequency wavelet coefficients, selecting coefficients, and performing inverse transform to evaluate fusion results.
5：Data Analysis Methods:
The performance of the methods is evaluated using information entropy and average gradient as indicators.
