Mser (ImgLib2 Javadocs 0-SNAPSHOT API)

java.lang.Object
- net.imglib2.algorithm.componenttree.mser.Mser<T>

Type Parameters:

T - value type of the input image.

All Implemented Interfaces:

Iterable<Localizable>, Component<T,Mser<T>>
```
public final class Mser<T extends Type<T>>
extends Object
implements Component<T,Mser<T>>
```
A maximally stable extremal region (MSER) of the image thresholded at value(). The set of pixels can be accessed by iterating ( iterator()) the component. This is a node in a MserTree. The child and parent nodes can be accessed by getChildren() and getParent().

- Method Detail
  - value
```
public T value()
```
    Get the image threshold that created the extremal region.
    
    Specified by:
    
    value in interface Component<T extends Type<T>,Mser<T extends Type<T>>>
    
    Returns:
    
    the image threshold that created the extremal region.
  - size
```
public long size()
```
    Get the number of pixels in the extremal region.
    
    Specified by:
    
    size in interface Component<T extends Type<T>,Mser<T extends Type<T>>>
    
    Returns:
    
    number of pixels in the extremal region.
  - score
```
public double score()
```
    The MSER score is computed as |R_i - R_{i-\Delta}| / |R_i|.
    
    Returns:
    
    the MSER score.
  - mean
```
public double[] mean()
```
    Mean of the pixel positions in the region. This is a position vector (x, y, z, ...)
    
    Returns:
    
    mean vector.
  - cov
```
public double[] cov()
```
    Covariance of the pixel positions in the region. This is a vector of the independent elements of the covariance matrix (xx, xy, xz, ..., yy, yz, ..., zz, ...)
    
    Returns:
    
    vector of covariance elements.
  - iterator
```
public Iterator<Localizable> iterator()
```
    Get an iterator over the pixel locations (Localizable) in this connected component.
    
    Specified by:
    
    iterator in interface Iterable<Localizable>
    
    Returns:
    
    iterator over locations.
  - getChildren
```
public ArrayList<Mser<T>> getChildren()
```
    Get the children of this node in the MserTree.
    
    Specified by:
    
    getChildren in interface Component<T extends Type<T>,Mser<T extends Type<T>>>
    
    Returns:
    
    the children of this node in the MserTree.
  - getParent
```
public Mser<T> getParent()
```
    Get the parent of this node in the MserTree.
    
    Specified by:
    
    getParent in interface Component<T extends Type<T>,Mser<T extends Type<T>>>
    
    Returns:
    
    the parent of this node in the MserTree.
