| contents | Infrared small target detection plays a crucial role in military reconnaissance and air defense systems. However,existing low-rank sparse based methods still face high computational complexity when dealing with low-contrast small targets and complex dynamic backgrounds mixed with target-like interference. To address this limitation, we reconstruct the data into a fourth-order tensor and propose a new infrared small target detection model based on bilateral tensor ring decomposition, called BTR-ISTD. The approach begins by constructing a four-dimensional infrared tensor from an image sequence, then utilizes BTR decomposition to effectively distinguish weak spatial correlations from strong temporal-patch correlations while simultaneously capturing interactions between these two components. This model is efficiently solved under the proximal alternating minimization (PAM) framework. Experimental results demonstrate that the proposed approach outperforms several state-of-the-art methods in terms of detection accuracy, background suppression capability, and computational speed. |
