Problems solved by technology

This method is suitable for infrared images with relatively simple backgrounds, but it is not robust when dealing with infrared images with complex backgrounds.
In conclusion, the detection of small infrared targets in complex backgrounds is still a challenging subject

Abstract

The invention relates to an infrared small target detection method based on multi-scale mean filtering and saliency detection. Firstly, multi-scale mean filtering is used to achieve the effects of target enhancement and background suppression. Second, using the saliency detection algorithm, small infrared targets in complex backgrounds can be effectively detected while maintaining a low false alarm rate. The beneficial effect is that the signal energy of the real small target is strengthened after multiple filtering, and the effect of target enhancement and background suppression is achieved. Using the saliency detection algorithm, it can effectively detect small infrared targets in complex backgrounds while maintaining a low false alarm rate.

Description

technical field The invention belongs to an infrared small target detection method, in particular to an infrared small target detection method based on multi-scale mean filtering and saliency detection. Background technique Infrared small target detection in complex background is the core technology of infrared guidance system and an important means of military defense. Due to the characteristics of the infrared image itself, it is very difficult to detect small infrared targets: firstly, due to the generally long imaging distance, the target only occupies a small number of pixels in the image; secondly, due to the noise of the imaging system and the influence of background clutter, the target The signal is weak, and it is easy to be overwhelmed by complex backgrounds, such as overlapping in the background of clouds; finally, infrared targets lack effective shape and texture information. Regarding infrared small target detection, predecessors have done a lot of work. For e...
