Abstract
Image fusion is a key technology in thefield of digital image processing. In the present study, an effect-based pseudocolor fusion model of infrared and visible images based on the rattlesnakevision imaging system (the rattlesnake bimodal cell fusion mechanism and thevisual receptive field model) is proposed. The innovation point of the proposedmodel lies in the following three features: first, the introduction of a simplemathematical model of the visual receptive field reduce computationalcomplexity; second, the enhanced image is obtained by extracting the commoninformation and unique information of source images, which improves fusionimage quality; and third, the Waxman typical fusion structure is improved forthe pseudo color image fusion model. The performance of the image fusion modelis verified through comparative experiments. In the subjective visualevaluation, we find that the color of the fusion image obtained through theproposed model is natural and can highlight the target and scene details. Inthe objective quantitative evaluation, we observe that the best values on thefour indicators, namely standard deviation, average gradient, entropy, andspatial frequency, accounts for 90%, 100%, 90%, and 100%, respectively,indicating that the fusion image exhibits superior contrast, image clarity,information content, and overall activity. Experimental results reveal that theperformance of the proposed model is superior to that of other models and thusverified the validity and reliability of the model.
