Abstract:

Single-frame infrared small target detection is a challenging task due to the noise and clutter interference. Recent emerging deep learning methods achieve superior detection performance compared to traditional model-driven methods. However, these data-driven methods do not possess the explicit gradient encoding capability of local contrast methods. To overcome the restriction, we propose a holistic local contrast network (HoLoCoNet) in this letter to gradually couple the local contrast into the end-to-end network, which consists of a multiscaled multidirectional attention module (M2AM) to directly processes the input image, a multibranch dilated difference convolution module (D2CM) for secondary refinement of the multiscale features extracted by the backbone network, and a semantic-enhanced aggregation module (SEAM) for bottom-up feature fusion by enhancing shallow features with deep semantic knowledge. The experimental results on the widely accepted NUDT-SIRST and IRSTD-1K dataset demonstrate the rationality and effectiveness of the proposed HoLoCoNet with the probability of detection reaching 99.2 and 94.3.
