中文说明：本代码是基于DSIFT的多聚焦图像融合方法，的融合图像。图像融合技术包含一个重要分支，即多聚焦图像融合技术。该技术应用的载体为多聚焦图像。其由来是由于成像照相机的光学镜头受到聚焦深度的限制，想要用固定镜头一次性采集到所有远近处的清晰图像，是很难实现的。因此，为了得到整个场景的全聚焦图像，一般使用可变焦的镜头，对场景中不同景深的物体分别对焦，从而得到每个物体各自清晰显示的多幅源图像。接下来，对进行了配准操作的多源图像做信息整合，最后获取一幅融合图像，而该融
English Description：
This code is based on dsift multi focus image fusion method, the fusion image. Image fusion technology includes an important branch, namely multi focus image fusion technology. The carrier of this technology is multi focus image. The reason is that the optical lens of the imaging camera is limited by the focus depth, so it is difficult to capture all the clear images at a time with a fixed lens. Therefore, in order to get the full focus image of the whole scene, a zoom lens is generally used to focus the objects with different depth of field in the scene, so as to get multiple source images of each object clearly displayed. Next, the multi-source images that have been registered are integrated. Finally, a fusion image is obtained
