Method Details

_initialize

public void _initialize()

Specified by:

_initialize in class BaseFunction<T extends Tensor<T>>

isEntirelyBorder

protected boolean isEntirelyBorder(int outR0,
int outC0)

Do all regions interact with the image border? The provided point is the lower-extent of the output pixel which doesn't interact with input image border.

Parameters:

outR0 - Lower-extent row in output coordinates.

outC0 - Lower-extent column in output coordinates.

innerLowerExtent

public static int innerLowerExtent(int period,
int padding)

The lower extent in output coordinates for regions that are contained entirely inside the original image. s

Parameters:

period - Sampling period in input tensor pixels

padding - Padding added along lower extent to input tensor

Returns:

Lower extent in output tensor coordinates, inclusive

innerUpperExtent

public static int innerUpperExtent(int windowLength,
int period,
int padding,
int inputLength)

The upper extent int output coordinates for regions that are contained entirely inside the original image.

Parameters:

windowLength - Length of sampling window in input tensor pixel

period - Sampling period in input tensor pixels

padding - Padding added along lower extent to input tensor

inputLength - Length of the input tensor

Returns:

Upper extent in output tensor coordinates, exclusive

getPadding

public P getPadding()
