Compute leave-one-out error for each of the chips in the chart.
Compute leave-one-out error for each of the chips in the chart.
The error for a given chip is computed by excluding that chip from a chart. Color corrector is computed using all but that selected chip, then a delta between value of that chip and color computed for that chip by the corrector is determined (square root of sum of squares of color components differences).
deltas when each of the chips, in turn, is excluded.
