public abstract class SegmentStackIntoObjectsPooled<T extends InferenceModel>
extends SegmentationBean<SegmentStackIntoObjectsPooled<T>>

A base class for algorithms to segment a stack into one or more objects - using a pool of models

These models are typically CNN deep-learning models.

Method Details

segment

public SegmentedObjects segment(Stack stack,
 ExecutionTimeRecorder executionTimeRecorder)
                         throws SegmentationFailedException

Segments individually using a pool of size 1 just for one stack.

See segment(Stack, ConcurrentModelPool, ExecutionTimeRecorder) for more details.

Parameters:

stack - the stack to segment.

executionTimeRecorder - for measuring execution-times of operations.

Returns:

a collection of objects with corresponding confidence scores.

Throws:

SegmentationFailedException - if anything goes wrong during the segmentation.

createModelPool

public abstract ConcurrentModelPool<T> createModelPool(ConcurrencyPlan plan,
 Logger logger)
                                                throws CreateModelFailedException

Creates the model pool (to be used by multiple threads).

Parameters:

plan - the number and types of processors available for concurrent execution.

logger - the logger.

Returns:

the newly created model pool.

Throws:

CreateModelFailedException - if a model cannot be created.

segment

public abstract SegmentedObjects segment(Stack stack,
 ConcurrentModelPool<T> modelPool,
 ExecutionTimeRecorder executionTimeRecorder)
                                  throws SegmentationFailedException

Segments a stack to produce an object-collection.

Any created objects will always exist inside the stack's Extent.

Parameters:

stack - the stack to segment.

modelPool - the pool of model instances which can each be used for inference (in parallel).

executionTimeRecorder - measures execution-times of particular operations.

Returns:

a collection of objects with corresponding confidence scores.

Throws:

SegmentationFailedException - if anything goes wrong during the segmentation.

resolve

protected Path resolve(String modelFilename)
                throws InitializeException

Resolves a relative filename for a model into a path, relative to the model directory.

Parameters:

modelFilename - the filename for the model (to the model directory).

Returns:

an absolute path to the model.

Throws:

InitializeException - if a bean requires initialization, but has not been initialized.
