Constructor Detail

ManyBlobs

public ManyBlobs()

ManyBlobs

public ManyBlobs(ij.ImagePlus binaryImage)

Parameters:

imp - Binary Image

Method Detail

setBackground

public void setBackground(int val)

Mutator to modify the background target. This method will switch the background to the user's specification and also swap the OBJECT value to be the opposite. e.g. If the users specifies the background to be black, the objects (blobs) looked for will be white.

Parameters:

backgroundVal - : 0 or 1 (black/white respectively)

findConnectedComponents

public void findConnectedComponents()

Start the Connected Component Algorithm

getLabeledImage

public ij.ImagePlus getLabeledImage()

Returns:

Return the labeled Image.

setLabeledImage

public void setLabeledImage(ij.ImagePlus p)

getSpecificBlob

public Blob getSpecificBlob(int x,
                            int y)

Returns a specific Blob which encompasses a point

Parameters:

x - x coordinate of the point

y - y coordinate of the point

Returns:

The blob which contains the point, otherwise null

getSpecificBlob

public Blob getSpecificBlob(Point p)

Returns a specific blob which encompasses a point

Returns:

The blob which contains the point, otherwise null

getBlobByLabel

public Blob getBlobByLabel(int id)

filterBlobs

public ManyBlobs filterBlobs(double lowerLimit,
                             double upperLimit,
                             String methodName,
                             Object... methodparams)

Filter all blobs which feature (specified by the methodName) is higher than the lowerLimit or lower than the upper limit. For instance: filterBlobs(Blob.GETENCLOSEDAREA,40,100) will filter all blobs between 40 and 100 pixel².

Parameters:

methodName - Getter method of the blob feature (double as return value).

lowerLimit - Lower limit for the feature to filter blobs.

upperLimit - Upper limit for the feature to filter blobs.

Returns:

The filtered blobs.

filterBlobs

public ManyBlobs filterBlobs(double[] limits,
                             String methodName,
                             Object... methodparams)

Filter all blobs which feature (specified by the methodName) is higher than the lowerLimit and lower than the upper limit. For instance: filterBlobs(Blob.GETENCLOSEDAREA,40,100) will filter all blobs between 40 and 100 pixel².

Parameters:

methodName - Getter method of the blob feature (double as return value).

limits - First Element is the lower limit, second element is the upper limit

Returns:

The filtered blobs.

Throws:

NoSuchMethodException

filterBlobs

public ManyBlobs filterBlobs(double lowerlimit,
                             String methodName,
                             Object... methodparams)

Filter all blobs which feature (specified by the methodName) is higher than the lower limit. For instance: filterBlobs(Blob.GETENCLOSEDAREA,40) will filter all blobs with an area higher than 40 pixel²

Parameters:

methodName - Getter method of the blob feature (double as return value).

lowerlimit - Lower limit for the feature to filter blobs.

Returns:

The filtered blobs.

Throws:

NoSuchMethodException
