Automatic label correction based on CCESD

by   Jiawei Liu, et al.

In the computer-aided diagnosis of cervical precancerous lesions, it is essential for accurate cell segmentation. For a cervical cell image with multi-cell overlap (n>3), blurry and noisy background, and low contrast, it is difficult for a professional doctor to obtain an ultra-high-precision labeled image. On the other hand, it is possible for the annotator to draw the outline of the cell as accurately as possible. However, if the label edge position is inaccurate, the accuracy of the training model will decrease, and it will have a great impact on the accuracy of the model evaluation. We designed an automatic label correction algorithm based on gradient guidance, which can solve the effects of poor edge position accuracy and differences between different annotators during manual labeling. At the same time, an open cervical cell edge segmentation dataset (CCESD) with higher labeling accuracy was constructed. We also use deep learning models to generate the baseline performance on CCESD. Using the modified labeling data to train multiple models compared to the original labeling data can be improved 7 (AP). The implementation is available at
