Abstract

Abstract

En 中文
• Decision-level transition maps encode VVC recompression traces. • Stage-aware discrepancy fusion improves VVC double compression detection. • CTPDE-Net models compressional-temporal evolution across recompressions. • Robust results are achieved under diverse QP and Preset settings. • PDCM and CCDA transfer effectively to multiple backbone architectures.
