Table 1 Distributions of DCT coefficient difference values according to T (%)
Threshold | \( \%\left\{{F}_{inter}^{\to}\left(u,v\right)\le T\right\} \) | \( \%\left\{{F}_{inter}^{\downarrow}\left(u,v\right)\le T\right\} \) | \( \%\left\{{F}_{inter}^{\searrow}\left(u,v\right)\le T\right\} \) |
|---|---|---|---|
T = 3 | 68.8 | 68.3 | 67.5 |
T = 4 | 72.3 | 71.8 | 71.0 |
