Constructor Detail

Accumulator

public Accumulator(int N)

Creates a N wide accumulator

Method Detail

init

public void init()

Sets every squares to zero

update

public boolean update(BooleanMatrix boolMat,
                      double gradient)

Increments each square of the accumulator that correspond with a "true" value square of the boolean matrix

Parameters:

boolMat - a boolean array with the same dimension than the accumulator (strongly recommanded)

gradient - the incrementation value

get

public double get(int x,
                  int y)

Returns the value of the square at (x,y)
