Area of Science:

Medical diagnostics
Microbiology
Image processing

Background:

Manual microscopy for trichomonad detection in leukorrhea suffers from low specificity and efficiency due to subjective interpretation and morphological similarities with human leukocytes.
Existing automated methods struggle with the variable morphology and size of trichomonads, hindering accurate classification.

Purpose of the Study:

To develop an automated detection method for trichomonads in leukorrhea using dynamic characteristics.
To improve the accuracy and efficiency of trichomonad identification compared to traditional manual microscopy.

Main Methods:

An improved Kalman background reconstruction algorithm was employed for moving object detection.
The algorithm considered the dynamic characteristics of trichomonads at room temperature for automated identification.

Main Results:

The proposed algorithm accurately identified trichomonads, effectively eliminating issues like tailing and ghost images.
The method demonstrated robustness against variations in lighting, focal length, and lens shift.

Conclusions:

The improved Kalman background reconstruction algorithm offers a robust and efficient solution for automated trichomonad detection in leukorrhea.
This approach overcomes the limitations of manual microscopy and morphological-based classification, paving the way for improved gynecological diagnostics.
