Abstract: In order to solve the problem that the current algorithms cannot eliminate the background effectively and
lead to the low detection rate, a infrared dim target detection approach based on fractional integral operator is proposed.
Firstly, through studying the fractional integral theory and analyzing its predominant sharp low-pass frequency character, the
fractional integral operator is introduced to combine with the guard ring technology to eliminate the infrared background.
Then, by analyzing the space features of targets and background edg
