Presentation title:

Image restoration techniques and applications based on scattering suppression

Abstract: 

Scattering effects seriously affect the imaging quality of computer vision systems. The typical cases include image degradation, contrast reduction, and inconspicuous details due to hazy weather. These problems can seriously impair the performance of some image and video information-based tasks, such as road surveillance, fire search and rescue, etc. In addition, underwater imaging also faces wavelength-selective scattering and non-uniform scattering of ambient imaging light by particles such as underwater plankton. This causes problems such as blurring and even color bias of underwater images. The problem is a major obstacle to the development of underwater image vision technology. In this report, we establish an optical scattering imaging model for atmosphere and underwater and analyze its degradation effects and laws. Based on the fusion of multiple image enhancement and recovery algorithms and deep learning methods, image recovery algorithms for atmospheric and underwater scattering effect suppression are proposed, respectively. The imaging quality in hazy weather can be significantly improved, and the color bias and scattering blur of underwater imaging can be suppressed. And at the end, we outline the application of the proposed algorithms in practical scenarios such as natural gas pipeline inspection and marine pasture monitoring.
