| 摘 要： | 本文首先阐述了基于塔形分解的图像融合的原理和步骤，然后针对实时嵌入式系统的特点提出了一种新的称为固定权的融合规则，该方法具有简单，可行，便于调节的特点。接着，通过Matlab仿真和交叉熵的客观评价方法证明了固定权新融合规则的可行性和有效性。最后，在DSP平台下，用基于固定权新融合规则的算法实现了两幅大小为240×320的可见光和红外光图像的实时图像融合。

| Abstract: | The principle and step of image fusion based on pyramidal decompositions is presented in this paper, then, a new fusion rule named constant weight is studied for the real-time embedded system., the marked traits of constant weight method are as follows： simplicity, feasibility and easy to adjust. In addition, the performance of new fusion scheme has been proved feasibility and validity using the simulation of Matlab and the quantitative evaluation named cross-entropy. Finally, we implemented the real-time fusion processing on visible light and infrared images with the size of 240×320 on DSP based on the improved algorithm. |
