Description
In the current master of VTM, commit 796c74ad, the rate-distortion results when “REUSE_CU_RESULTS” is equal to 1 and those when “REUSE_CU_RESULTS” is equal to 0 are not identical. Given that “REUSE_CU_RESULTS at 1 enables to reuse the compression information of a past CU that is “equivalent” to the current CU to be compressed, the rate-distortion results for these two cases must be identical.
Please find attached “bjontegaards_ai_one_vtm_19_hhi_master_2023_18_01_reuse_cu_results_off.csv” and “bjontegaards_ai_one_vtm_19_hhi_master_2023_18_01_reuse_cu_results_on.csv” the two rate-distortion results using commit 796c74ad when “REUSE_CU_RESULTS” is 0 and “REUSE_CU_RESULTS” is 1 respectively, in AI single frame.
