Background:

Deep learning object detection relies heavily on large-scale, fully-annotated datasets, which are costly and difficult to acquire for real-world applications.
Human object detection utilizes prior knowledge and few examples for efficient learning and generalization, a capability current deep learning models struggle to replicate.
Existing methods face limitations in leveraging diverse object supervision and generalizing to new domains with limited annotated data.

Purpose of the Study:

To propose a novel Progressive Object Transfer Detection (POTD) framework that mimics human-like learning for object detection.
To develop a method that effectively utilizes various object supervision from different domains to enhance target detection tasks with minimal annotations.
To improve the efficiency and robustness of object detection in scenarios with limited labeled data.

Main Methods:

The Progressive Object Transfer Detection (POTD) framework progressively integrates object supervision from diverse domains.
The framework comprises two stages: Low-Shot Transfer Detection (LSTD) to distill knowledge from source detectors using few annotations, and Weakly-Supervised Transfer Detection (WSTD) employing a recurrent object labeling mechanism.
LSTD provides crucial supervision to enhance the robustness of the target detector during the WSTD stage.

Main Results:

Extensive experiments on challenging detection benchmarks demonstrate the effectiveness of the POTD framework.
POTD significantly outperforms recent state-of-the-art approaches in object detection tasks with limited annotations.
The proposed method successfully leverages diverse object supervision and improves detection performance through its two-stage transfer learning approach.

Conclusions:

The Progressive Object Transfer Detection (POTD) framework offers a powerful solution for object detection in data-scarce environments.
The human-like learning procedure and the LSTD/WSTD stages enable efficient knowledge transfer and robust detection with minimal annotations.
POTD represents a significant advancement in leveraging prior knowledge and weak supervision for practical object detection applications.
