Construct with the initial minimum and maximum size set to zero.

AbstractMultiScaleObjectDetector

protected AbstractMultiScaleObjectDetector(int minSize,
                                int maxSize)

Construct with the given initial minimum and maximum detection sizes.

Parameters:

minSize - minimum size

maxSize - maximum size

Method Detail

setROI

public void setROI(org.openimaj.math.geometry.shape.Rectangle roi)

Description copied from interface: ObjectDetector

(Optional operation).

Set the region of interest within the image to search for objects. Setting to null means to search the whole image.

Specified by:

setROI in interface ObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT>

Parameters:

roi - the region of interest

setMinimumDetectionSize

public void setMinimumDetectionSize(int size)

Description copied from interface: MultiScaleObjectDetector

(Optional operation).

Set the minimum detection size.

Specified by:

setMinimumDetectionSize in interface MultiScaleObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT>

Parameters:

size - the minimum detection size.

setMaximumDetectionSize

public void setMaximumDetectionSize(int size)

Description copied from interface: MultiScaleObjectDetector

(Optional operation).

Set the maximum detection size. A size less than or equal to 0 indicates there is no maximum size.

Specified by:

setMaximumDetectionSize in interface MultiScaleObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT>

Parameters:

size - the maximum detection size.

getMinimumDetectionSize

public int getMinimumDetectionSize()

Description copied from interface: MultiScaleObjectDetector

(Optional operation).

Get the minimum detection size.

Specified by:

getMinimumDetectionSize in interface MultiScaleObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT>

Returns:

the minimum detection size.

getMaximumDetectionSize

public int getMaximumDetectionSize()

Description copied from interface: MultiScaleObjectDetector

(Optional operation).

Get the maximum detection size. A size less than or equal to 0 indicates there is no maximum size.

Specified by:

getMaximumDetectionSize in interface MultiScaleObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT>

Returns:

the maximum detection size.
