CE3: Cross-component linear model simplification (Test 5.1)
Authors: Guillaume Laroche Canon J. Taquet Canon C. Gisquet Canon Patrice Onno Canon
Abstract
This contribution reports the results of CE3 test 5.1. This CE3 replaces the LMS algorithm by a straight-line equation for CCLM mode Luma to Chroma prediction. More precisely, this CE3 is related to a modification of the determination of the linear model parameters and . In the current VTM2.0 implementation, these parameters are derived by minimizing the regression error between the neighbouring Luma and Chroma samples. In this CE3, 2 Luma samples and their corresponding Chroma samples are used to obtain the linear model parameters and in order to avoid the regression error minimization algorithm where all Luma and Chroma samples from the border are considered.
