A Two-Stage Cascaded Detection Scheme for Double HEVC Compression Based on Temporal Inconsistency

Table 6

The detection accuracies with different resolutions (%).

	Recompression with the increased bitrate			Recompression with the decreased bitrate

GVPF [17]	95.36	93.42	93.67	76.57	72.03	71.29
CNN-LSTM [21]	95.59	92.75	92.88	84.15	80.33	78.48
Proposed	98.81	96.17	96.32	88.51	87.92	86.40
