Class MultiScaleObject

Object

MultiScaleObject

public class MultiScaleObject
extends Object

An ObjectMask that exists at multiple scales.

Specifically the scales are:

• the scale associated with the input-image.
• the scale associated with the segmentation (usually a scaled down version of the above).

Constructor Details

MultiScaleObject

public MultiScaleObject(Supplier<ObjectMask> inputScale,
 Supplier<ObjectMask> modelScale)

Creates with a separate supplier of an ObjectMask for each respective scale.

The suppliers will be cached internally, so are guaranteed to be called maximally one time.

Parameters:

inputScale - supplies an ObjectMask for the input-scale.

modelScale - supplies an ObjectMask for the model-scale.

Method Details

extractFrom

public static <T> MultiScaleObject extractFrom(DualScale<T> dual,
 Function<T, ObjectMask> extractObject)

Creates a new MultiScaleObject by extracting a ObjectMask from a DualScale.

This extract occurs lazily, only when needed.

Type Parameters:

T - the element-type of the DualScale.

Parameters:

dual - the DualScale the object is extracted from.

extractObject - a function applied to the respective scale in DualScale to extract an ObjectMask.

Returns:

a newly created MultiScaleObject, as per above.

extractFrom

public static <T,S> MultiScaleObject extractFrom(DualScale<T> dual1,
 DualScale<S> dual2,
 BiFunction<T, S, ObjectMask> extractObject)

Creates a new MultiScaleObject by extracting a ObjectMask from two DualScales.

This extract occurs lazily, only when needed.

Type Parameters:

T - the element-type of dual1.

S - the element-type of dual2.

Parameters:

dual1 - the first DualScale the object is extracted from.

dual2 - the second DualScale the object is extracted from.

extractObject - a function applied to the respective scale in the two DualScales respectively to extract an ObjectMask.

Returns:

a newly created MultiScaleObject, as per above.

getInputScale

public ObjectMask getInputScale()

Gets the ObjectMask at the scale associated with the input-image.

Returns:

the object.

getModelScale

public ObjectMask getModelScale()

Gets the ObjectMask at the scale associated with the segmentation.

Returns:

the object.
