That call is necessary because if the user moves the columns around, the view s index for the column doesn t match the model s index for the column. For example, the user might drag the Vegetarian column (which the model considers to be at index 4) so it s displayed as the first column — at view index 0.

- In this work, a novel coding characteristics prediction scheme is presented to improve
R-D modeling, by exploiting spatio-temporal correlations. Two different approaches to the prob-
lem of optimum bit allocation at a macroblock-by-macroblock basis are achieved, one of which is
developed on a modified MPEG-4 Q2 rate model and the other on a linear rate model. Extensive
experiments show that the linear scheme is a bit more accurate than the quadratic one while they
achieve similar coding performance. It′s also shown that both the two schemes significantly ex-
ceed JVT G012, the current standardized RC scheme.
