public Abstract3x3TableOperation()

Method Detail

getTable

protected abstract boolean[] getTable()

The index to the table that's returned is built by examining each pixel and accumulating 2^pixel number. The pixels are numbered like this:

 0 1 2
 3 4 5
 6 7 8
 

Returns:

a 512-element table that holds the truth values for each 3x3 combination

getExtendedValue

protected abstract boolean getExtendedValue()

Gets default value for neighborhood pixels outside of the image. For example, an erosion operator should return true because otherwise pixels at the border would be eroded without evidence that they were not in the interior, and vice-versa for dilate.

Returns:

the extended value for this operation

calculate

protected <T extends net.imglib2.type.BooleanType<T>> net.imglib2.img.Img<T> calculate(net.imglib2.img.Img<T> source)
