  • Biomedical imaging
  • Computer vision
  • Medical diagnostics

Background:

  • Microscopic examination is crucial for biomedical research and clinical diagnosis.
  • Object detection in bioimages enhances efficiency and diagnostic objectivity.
  • Limited annotated datasets hinder the deployment of object detection models for microscopic elements.

Purpose of the Study:

  • To propose a data-efficient object detection method for microscopic images.
  • To overcome limitations of standard augmentation techniques that can distort micro-morphological information.
  • To improve the performance and trustworthiness of AI systems in microscopic analysis.

Main Methods:

  • A feature activation map-guided boosting mechanism was developed for microscopic object detection.
  • The method was tested on Chinese herbal medicine and urine sediment micrograph datasets.
  • Standard augmentation methods were evaluated against the proposed boosting mechanism.

Main Results:

  • The boosting mechanism significantly improved mean Average Precision (mAP) on both datasets.
  • Chinese herbal medicine dataset mAP increased by 16.3% (baseline) and 5.8% (strong baseline).
  • Urine sediment dataset mAP improved by 8.0% (baseline) and 2.6% (strong baseline).

Conclusions:

  • The proposed boosting mechanism enhances data efficiency and performance in microscopic object detection.
  • The method demonstrates strong generalizability and interpretability, suitable for biomedical applications.
  • This approach facilitates the integration of AI in clinical diagnosis and research, building analyst trust.
