Infrared Small Target Detection

Ask about this topic

Overview

Infrared small target detection aims to localize dim objects that may occupy only a few pixels and resemble background clutter. Methods range from low-rank and sparse decomposition to CNN and transformer-style detectors that use multiscale features, frequency cues, physical priors, and, for video, motion across frames. Current work also explores point- or box-supervised training, pseudo-labels, and lightweight models for real-time use. A central challenge is improving detection and localization without increasing false alarms, especially across unfamiliar scenes, degraded imagery, and limited or noisy annotations.
