Abstract—In this paper, we propose a novel method to recovery the haze-free image based on the improved optical model with the single image based depth estimation. In this work, the objective transmission and distance transmission are present to improve the optical model for obtaining the haze-free image. Firstly, the color clustering method is used to segment the image into several regions by color similarity. Then, the graph-based segmentation is used to calculate the depth information. Next, the atmosphere light is estimated according to the distance transmission. And finally, the improved optical model is used to estimate the haze-free image. The experimental results show that our method is more effective and able to get better results than other single image based methods.
