Fig. 3. Computational complexity in terms of CPU cycles. The btf-ADST was implemented using streaming SIMD extension 2 and the experiments were running on a 64-bit platform.
Fig. 2. Coding performance comparison of 2D-DCT, ADST/DCT hybrid transform, and btf-ADST/DCT hybrid transform for sequence harbour at CIF resolution.
Fig. 1. Theoretical coding gains of btf-ADST, ADST, and DCT, relative to KLT, all applied to the prediction residuals, plotted versus the inter pixel correlation coefficient; the block dimension is 8× 8.
