- Abstract:
-
In order to alleviate the interference of complex backgrounds in infrared small target detection, a new infrared small target detection method is proposed. The new method combines background estimation with local contrast to improve the detection performance of the algorithm. The main work includes the following aspects: First, a double-layer max-mean background estimation algorithm that is more suitable for small target detection is proposed to get a more accurate background benchmark. Then, a ratio-difference joint local contrast measure is proposed between the raw image and the estimated background to enhance the different sizes of true targets while simultaneously suppressing various types of complex backgrounds. The analysis and comparison in the experiment show its effectiveness and robustness.
