海空背景下红外弱小目标检测方法
A method for detecting small infrared targets in the sea or sky
摘要
Abstract
To improve the probability of locating the objective of a maritime search and rescue, a new method was developed that significantly enhances the detection of small infrared targets in the sea or sky. In this method, the background is predicted and then the predicted image is compared with the actual infrared image to identify potential targets. The differentiated image is then filtered by the Top-Hat operator to remove the influence of remnant wave noise. Finally, self-adapting threshold detection was used to detect the orientation of the small target. By comparing the effectiveness of this method with that of a Top-Hat transform of single-frame images, it was proven that this method effectively eliminates the influence of waves, providing small infrared targets with higher brightness, thereby greatly assisting in maritime search and rescue.关键词
