Detection of cervical cell based on multi-scale spatial information

Abstract

Cervical cancer poses a significant health risk to women. Deep learning methods can assist pathologists in quickly screening images of suspected lesion cells, greatly improving the efficiency of cervical cancer screening and diagnosis. However, existing deep learning methods rely solely on single-scale features and local spatial information, failing to effectively capture the subtle morphological differences between abnormal and normal cervical cells. To tackle this problem effectively, we propose a cervical cell detection method that utilizes multi-scale spatial information. This approach efficiently captures and integrates spatial information at different scales. Firstly, we design the Multi-Scale Spatial Information Augmentation Module (MSA), which captures global spatial information by introducing a multi-scale spatial information extraction branch during the feature extraction stage. Secondly, the Channel Attention Enhanced Module (CAE) is introduced to achieve channel-level weighted processing, dynamically optimizing each output feature using channel weights to focus on critical features. We use Sparse R-CNN as the baseline and integrate MSA and CAE into it. Experiments on the CDetector dataset achieved an Average Precision (AP) of 65.3%, outperforming the state-of-the-art (SOTA) methods.
