The first demonstration of ultra-large-scale phase retrieval at the 8K level (\(7680 \times 4320\) \(\times\)3 pixels). The imaging modality is CDP with 5 modulations. At such a large scale, only the AP and the reported LPR techniques still work, while the other ones fail due to high computational complexity. The results validate that LPR significantly outperforms AP with effective noise removal and detail reservation
