Abstract: Scattering media will change the transmission direction and transmission path of photons, resulting in a decrease in image quality and even forming speckle. Theoretically, information of targets can be recovered by the transmission matrix of the scattering medium, but the process to solve the transmission matrix is too complicated. Then, the rapid development of deep learning provides a new method to solve the problem of imaging through scattering media. As a typical method for solving inverse problems, it can recover the target information accurately, improve the imaging quality, solve many difficult problems, and achieve important research results through scattering imaging. Existing learning methods could be divided into two categories: supervised learning and unsupervised learning. Herein, we summarize the progress of imaging through scattering media based on the two methods, and analyze the advantages and challenges of this technology. Besides, based on the aspects of network structure, imaging quality, generalization and so on, a various of scattering imaging technologies are analyzed and compared. Finally, the development trends are prospected.
