Monocular Single-Image Scene Restoration

As pointed out in Sect. 7.1 , this chapter introduces the method of scene restoration based on monocular single image. According to the introduction and discussion in Sect. 2.2.2 , it is actually an ill-conditioned problem to use only monocular single image for scene restoration. This is because when the 3D scene is projected onto the 2D image, the depth information is lost. However, from the practice of human visual system, especially the ability of spatial perception (see [1]), in many cases, many depth clues are still retained in the image, so it is possible to recover the scene from it under the condition of certain constraints or prior knowledge [2–4].
