1.Although extensive research efforts have been focused on this field in past decades, small target detection against complicated backgrounds still remains an open issue.
2. Thus, this method has been drawing a lot of attention.
3. Recently, target detection methods based on the local difference have attracted much attention, for example, the xx method , the bb method , and so on.
4. These effects make the target detection more difficult. In order to detect a small target effectively, various algorithms have been developed in the past few decades.
5. Therefore, small target detection in complex infrared background is considered a difficult and chanllenging problem. Although many research efforts have been focused on this area in past decades, it still remain a open problem.
6. Therefore, detecting small targets in a single image is often necessary in such applications, and this problem is attracting much attention in recent years.
7. Therefore, many researchers have paid much attention to the study of IR small-target detection, especially to those images that are against complex and noisey backgrounds.
8. This produces great difficulties in the detection of IR images. Although many research efforts have been foucused on the detection of IR small targets against complex and noisy backgrounds in past decades, it still remains an open problem.
9.Therefore, the research of single-frame infrared small target detection is of great importance and has attracted a lot of attention in recent years.
