Abstract
This study optimizes YOLOv11 for vehicle detection in low-visibility environments (rain, fog, low-light) using CCTV data. Systematic evaluation of batch sizes (8, 16, 32), image resolutions (228, 448, 640), and optimizers (AdamW, SGD, Adam, etc.) identified the optimal configuration: batch size 16, resolution 640x640, AdamW optimizer. The model achieved mAP@0.5 of 0.896 and mAP@0.5-0.95 of 0.678, with real-time inference at 122 FPS (8.2 ms/img) on an NVIDIA RTX 4090 GPU.

Comparative Study of Enhanced Deep Learning Models for Cervical Pap Smear Cell Segmentation
A strictly fair comparative benchmark of four deep learning architectures (U-Net, U-Net++, Swin-UNet, SegNet) for cervical cell semantic segmentation on the Herlev dataset. Swin-UNet achieved the highest performance (F1: 0.8868 ± 0.0027; IoU: 0.7974 ± 0.0043), with statistical significance confirmed via one-way ANOVA and Bonferroni-corrected pairwise t-tests.
