PCReg-Net: Progressive Contrast-Guided Registration for Cross-Domain Image Alignment

Researchers have developed PCReg-Net, a lightweight AI framework for cross-domain image registration that achieves real-time performance at 141 FPS with only 2.56M parameters. The system uses a progressive contrast-guided approach with four modules to align images across different domains, showing improvements over traditional and deep learning baselines on retinal and microscopy benchmarks.
