Abstract: Abstract：Introduce a kind of improved algorithm which is used to process the images cranking with the condition of low visibility. We use the physical model of atmosphere to recovery the quality of images as the condition in the sunshine. This measure has been described in some papers before. The different between the algorithm here and the measure in other papers before is that we do not use the RGB colour space but HSI colour space, and when we seek for the “disappeared point” and divide up the area of sky the algorithm does not depand on human eyes but can finish with itself,that is it has self adaptation. The emulation by MATLAB shows that this algorithm has the greater effect and has a well practicality in image processing.
