SparseScaleGradient

public SparseScaleGradient()

Method Details

setWidth

public abstract void setWidth(double width)

Sets how wide the gradient operator is in pixels

Parameters:

width - width in pixels

setImage

public void setImage(T input)

Description copied from interface: SparseImageOperator

Specifies the image being processed.

Specified by:

setImage in interface SparseImageOperator<T extends ImageGray<T>>

Parameters:

input - Image being processed

isInBounds

public boolean isInBounds(int x,
 int y)

Description copied from interface: SparseImageOperator

Checks to see if the entire sample region is contained inside the image or not. Depending on the implementation it might be able to handle out of bounds pixels or not.

Specified by:

isInBounds in interface SparseImageOperator<T extends ImageGray<T>>
