Background:

Small object detection is crucial but challenging due to low resolution in complex scenes.
Existing methods often struggle to balance detection speed and accuracy.

Purpose of the Study:

To propose a lightweight multi-scale network (LMSN) for improved small object detection.
To enhance both the accuracy and efficiency of detecting small objects.

Main Methods:

Developed a lightweight multi-scale network (LMSN) incorporating multi-scale feature fusion.
Integrated a lightweight receptive field enhancement module to boost feature extraction.
Employed an efficient channel attention module to improve feature representation.

Main Results:

LMSN achieved mAP of 75.76% on PASCAL VOC and 89.32% on RSOD datasets.
Demonstrated significant improvements over MobileNetv2-SSD (5.79% and 11.14% higher, respectively).
Achieved high inference speeds of 61 FPS and 64 FPS on the respective datasets.

Conclusions:

The proposed LMSN effectively addresses the challenges of small object detection.
LMSN offers a superior balance of speed and accuracy compared to current state-of-the-art methods.
