| Test 3 - Hybrid 1-D/2-D string-based index coding
This test evaluates the colour index map coding proposed in JCTVC-R0268/R304 using hybrid 1D/2D string match based index compression. 1-D string match is performed within current CU, while hybrid 1D/2D search can be extended to the left 3 CTUs. More details could be found JCTVC-R0268/R0304
The best results were for test 3.
Lossy coding gain is 0.0 to 3.4% with current CU plus 3 to its left for IBC, depending on the category of test material.
Lossy coding gain is 0.0 to 1.9% relative to full-frame IBC, depending on the category of test material.
