Class Mask

java.lang.Object

bunwarpj.Mask

public class Mask
extends Object

This class is responsible for the mask preprocessing that takes place concurrently with user-interface events. It contains methods to compute the mask pyramids.

Constructor Summary

Constructor and Description
Mask(ij.process.ImageProcessor ip, boolean take_mask) Constructor, the input image is used only to take the image size if take_mask is false, otherwise, it is used as the mask information.
Mask(int width, int height) Create mask of specific size (all pixels set to true)

Constructor Detail

Mask

public Mask(ij.process.ImageProcessor ip,
            boolean take_mask)

Constructor, the input image is used only to take the image size if take_mask is false, otherwise, it is used as the mask information.

Parameters:

ip - image

take_mask - flag to take the mask information from input image processor

Mask

public Mask(int width,
            int height)

Create mask of specific size (all pixels set to true)

Parameters:

width - mask width

height - mask height

Method Detail

BoundingBox

public void BoundingBox(int[] corners)

Bounding box for the mask. An array is returned with the convention [x0,y0,xF,yF]. This array is returned in corners. This vector should be already resized.

Parameters:

corners - array of coordinates of the bounding box

clearMask

public void clearMask()

Set to true every pixel of the full-size mask.

fillMask

public void fillMask(int tool)

Fill the mask associated to the mask points.

Parameters:

tool - option to invert or not the mask

getValue

public boolean getValue(double x,
                        double y)

Get the value of the mask at a certain pixel. If the sample is not integer then the closest point is returned.

Parameters:

x - x- coordinate of the pixel

y - y- coordinate of the pixel

Returns:

value of the mask at the pixel in (x,y)

getPoint

public Point getPoint(int i)

Get a point from the mask.

Parameters:

i - index of the point in the polygong

Returns:

corresponding point

isFromStack

public boolean isFromStack()

Check if the mask was taken from the stack.

Returns:

True if the mask was taken from the stack

numberOfMaskPoints

public int numberOfMaskPoints()

Get the number of points in the mask.

Returns:

number of point of the polygon that composes the mask

readFile

public void readFile(String filename)

Read mask from file. An error is shown if the file read is not of the same size as the previous mask.

Parameters:

filename - name of the mask file

showMask

public void showMask()

Show mask.

setMaskPoints

public void setMaskPoints(Vector<Point> listMaskPoints)

Set the mask points.

Parameters:

listMaskPoints - list of points composing the mask

setValue

public void setValue(int u,
                     int v,
                     boolean value)

Sets the value of the mask at a certain pixel.

Parameters:

u - x- coordinate of the pixel

v - y- coordinate of the pixel

value - mask value to be set
