Description copied from interface: Classifier

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

Specified by:

classify in interface Classifier

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

public void updateCaches(StageTreeClassifier cascade)

Description copied from interface: Classifier

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

Specified by:

updateCaches in interface Classifier

Parameters:

cascade - the tree of stages
