Pad an image to specific target dimensions. More...
Inheritance diagram for PadDimsOperation:Pad an image to specific target dimensions.
This operation expands an image by adding padding pixels to any or all sides. The value of the border can be specified by the padding mode. The padding mode can be one of the following:
For label maps (i.e. modality == Modality::LABEL), a separate padding mode and value can be specified:
Note: the padding widths are evenly distributed to the left and right of the input image. If the difference \(\delta\) between the target dimensions and the input dimensions is odd, the padding is distributed as \(\delta / 2\) to the left and \(\delta / 2 + 1\) to the right.

|
overridevirtual |
Virtual function that every subclass should override.
Default implementation does nothing, so if those function are not implemented in a derived class, they won't act on the input in any way.
Reimplemented from Operation.
|
inlineoverridevirtual |
Returns whether the operation is guaranteed to not modify its input element, either because it computes its output out-of-place or because it is a no-op.
This can be used to decide whether a copy of the input should be made before calling the Operation::process function. Note that this only relates to the overloads taking specific elements as inputs (e.g. images, keypoints, etc.), since the Operation::process(DataItem& item) function always modifies its input.
true, because this Operation does not modify its input data. Reimplemented from Operation.

overridevirtual |
|
overridevirtual |
Returns specifications for a PadOperation with inverse properties.
Implements InvertibleOperation.
|
overridevirtual |
Set the operation's record identifier.
