On modes in geometric partitioning
Abstract
In this contribution three methods to reduce the number of modes for geometric partitioning are presented. These methods are claimed to reduce the number of modes from 64 to 50, 38 and 32, respectively. It is further claimed that these methods have a minor impact on the compression efficiency. It is also asserted that the number of combinations that are required to be tested during verification testing is reduced by up to 50%.
JVET-R0212 On modes in geometric partitioning [C. Hollmann, D. Liu, R. Yu, J. Ström (Ericsson)]
In this contribution three methods to reduce the number of modes for geometric partitioning are presented. These methods are claimed to reduce the number of modes from 64 to 50, 38 and 32, respectively. It is further claimed that these methods have a minor impact on the compression efficiency. It is also asserted that the number of combinations that are required to be tested during verification testing is reduced by up to 50%.
- Method 1 (50 modes): 0.03% RA, 0.00% LDB, 700 combinations to test (-22%)
- Method 2 (38 modes): 0.05% RA, 0.01% LDB, 532 combinations to test (-40%)
- Method 3 (32 modes): 0.07% RA, 0.06% LDB, 448 combinations to test (-50%)
The main intent is reducing the number of combinations for conformance testing.
The issue of testing a large number of combinations in geo was already discussed in the last meeting, and the adopted solution was agreed to be a good compromise.
