Class PixelPairFeatures

java.lang.Object
  bitmaps.PixelPairFeatures

public class PixelPairFeatures
extends java.lang.Object

Maintains a set of feature values (e.g. distance of average from 128) corresponding to a given pixel pair, in addition to retaining a pointer to the pixel pair itself. While some such features are dependent only on the pair itself, others depend on surrounding pairs, and as such must be set explicitly.

Field Summary

private double	absDistOfAvgFromCenter The absolute value of the difference from this pair's average value to the middle of the average values (127.5).

private int	col
private DEPixelPair	pair
private int	row
private double	weightedCombination1 Weighted combination of the avgSquareAdjacentAverageDiffs and absDistOfAvgFromCenter.

Field Detail

avgSquareAdjacentAverageDiffs

private double avgSquareAdjacentAverageDiffs

The average of the square of the differences in the averages of each pair of adjacent pixel pairs in the 9-pair block surrounding and including this pair. Adjacency includes diagonal adjacency. TODO: For now, we're only considering the pairs of pairs including the primary/center pair. TODO: Has morphed into more of a variance from the collective mean of the averages now.

absDistOfAvgFromCenter

private double absDistOfAvgFromCenter

The absolute value of the difference from this pair's average value to the middle of the average values (127.5).

weightedCombination1

private double weightedCombination1

Weighted combination of the avgSquareAdjacentAverageDiffs and absDistOfAvgFromCenter.

row

private int row

col

private int col

pair

private DEPixelPair pair
