			In this project, we analyzed and implemented the Exposure Fusion (EF) algorithm and extend it to create an all-in-focus image. We have test several images and make a simple comparison with tone mapping algorithms, which demonstrates the effectiveness and efficiency of EF.

	The EF algorithm could be used for a wide range of images. More experiment results are shown in Fig.14. One thing worthy of noticing is that because what EF algorithm does is to pick up those good pixels, we have to make sure that for any specific pixel, there has to be at least one good version for it in the image stack. Otherwise, the algorithm does not work. As a result, for extremely HDR scene or large DoF, more images are needed to capture all information contained in this scene. For normal HDR scene, auto-bracketing works well.		The EF algorithm could be used for a wide range of images. More experiment results are shown in Fig.14.
