Method Summary

Modifier and Type	Method and Description
float	classify(SummedSqTiltAreaTable sat, float wvNorm, int x, int y) Get the classification score for the window at (x, y) with the size defined by scale.
void	updateCaches(StageTreeClassifier cascade) Update the caches for a given scale (given by the cachedScale of the StageTreeClassifier).

Method Detail

classify

float classify(SummedSqTiltAreaTable sat,
               float wvNorm,
               int x,
               int y)

Get the classification score for the window at (x, y) with the size defined by scale.

Parameters:

sat - the summed area tables (integral images)

wvNorm - the normalisation based on the current window variance

x - the x-ordinate of the top-left of the window being tested

y - the y-ordinate of the top-left of the window being tested

Returns:

the classification score

updateCaches

void updateCaches(StageTreeClassifier cascade)

Update the caches for a given scale (given by the cachedScale of the StageTreeClassifier).

Parameters:

cascade - the tree of stages
