Abstract:

Realizing high robust infrared (IR) small target detection is of great significance in the face of complex and ever-changing IR image sequences. In this letter, we analyze the inherent relationship between local contrast, local gradient, and local background gray value of IR small targets from a new perspective. Based on this, a method for IR small target detection based on local contrast and the local gradient is proposed. In addition, a four-direction model is proposed to reduce the interference of bright background clutter in the target neighborhood. The experimental results show that the method proposed in this letter has high robustness and is suitable for detecting small IR targets in complex backgrounds.
