Abstract: Image dehazing is an important issue that interests both digital image processing and computer vision areas. This paper surveyed the recent techniques for image dehazing from the point view of physical model and digital image processing. Some fundamental principles of typical methods were summarized and the state-of-the-art progress was presented. For some typical, new haze removal algorithms, both the perceptual visual effect and objective evaluation data were presented to illustrate their haze removal performance. Finally, some future research topics on image dehazing were suggested.

Key words: image dehazing, image processing, physical model, image enhancement
