| Abstract: | The research was focused on haze of aerial digital image.An improved haze removal method was proposed based on haze imaging model,dark channel prior and adaptive contrast enhancement.Using different feature images acquired by Digital Sensor System 439 on an emergency response flight test,de-haze experiment was made.The detailed analysis and images quality assessment between the original and result images were accomplished.The experimental results showed that the method was feasible and available. |
| Keywords: | aerial digital image dark channel prior haze imaging model haze removal adaptive contrast enhancement |
