non-CE1: simplification of LIC parameters derivation
Authors: Philippe Bordes Technicolor F. Urban Technicolor Franck Galpin Technicolor
Abstract
This contribution proposes to simplify the derivation of the LIC parameters. The current method is based on LMS and quadratic sum terms operations whereas the proposal is based on linear sum terms operations. It is reported the proposed method reduce the number of operations (number of multiplications) with small loss (0.05% in RA and 0.04% in LDB).

This contribution proposes to simplify the derivation of the LIC parameters. The current method is based on LMS and quadratic sum terms operations whereas the proposal is based on linear sum terms operations. It is reported the proposed method reduces the number of operations (number of multiplications) with small loss (0.05% in RA and 0.04% in LDB).

Interesting simplification, but not for free in terms of compression.

JVET-N0410 and JVET-N0716 are other approaches with more reduction of complexity.
