This study introduces S3-Det, a novel detector for UAV imagery, excelling in identifying tiny objects despite scale variations and background noise. It offers superior accuracy and speed for real-time aerial surveillance.

Area of Science:

  • Computer Vision
  • Artificial Intelligence
  • Remote Sensing

Background:

  • Object detection in UAV imagery is hindered by scale variations, background noise, and tiny objects.
  • Lightweight detectors often degrade features, obscuring small object details with background information.

Purpose of the Study:

  • To develop a novel lightweight object detector, S3-Det, for enhanced performance in challenging UAV imagery.
  • To address feature degradation and improve the detection of small objects on edge devices.

Main Methods:

  • Introduced the Spectro-Spatial Synergistic Network (S3Net) as the backbone.
  • Designed an Implicit Recursive Feature Aggregator for efficient feature refinement.
  • Developed a decoupled detection head with large-kernel context regression and SIoU loss.
