Trichomonas Detection in Leucorrhea Based on VIBE Method

Abstract EN

Trichomonas examination is one of the important items in the leucorrhea routine detection.

And it cannot be recognized by still images because of the unstable morphology and unfixed focal location caused by motion characteristic.

We proposed an improved VIBE algorithm.

6 videos (totally 1414 frames) are collected for testing.

In order to compare the effects of the algorithms, we segment each frame artificially as ground truth.

Experiments show that percentage of correct classification (PCC) achieves 88%.

The proposed improved method can effectively suppress the false detection caused by the formed components such as epithelial cells in the leucorrhea microscopic image and the missed detection caused by the background model update during the movement.

At the same time, improvements can effectively suppress smear and ghost areas.

The algorithm proposed in this paper can be integrated into the leucorrhea automatic detection system.
