Detailed Description

template<typename TInputImage>
class itk::InPlaceLabelMapFilter< TInputImage >

Base class for filters that takes an image as input and overwrites that image as the output.

InPlaceLabelMapFilter is the base class for all process objects whose output image data is constructed by overwriting the input image data. In other words, the output bulk data is the same block of memory as the input bulk data. This filter provides the mechanisms for in place image processing while maintaining general pipeline mechanics. InPlaceLabelMapFilters use less memory than standard ImageToImageFilters because the input buffer is reused as the output buffer. However, this benefit does not come without a cost. Since the filter overwrites its input, the ownership of the bulk data is transitioned from the input data object to the output data object. When a data object has multiple consumers with one of the consumers being an in place filter, the in place filter effectively destroys the bulk data for the data object. Upstream filters will then have to re-execute to regenerate the data object's bulk data for the remaining consumers.

Since an InPlaceLabelMapFilter reuses the input bulk data memory for the output bulk data memory, the input image type must match the output image type. If the input and output image types are not identical, the filter reverts to a traditional ImageToImageFilter behaviour where an output image is allocated. In place operation can also be controlled (when the input and output image type match) via the methods InPlaceOn() and InPlaceOff().

Subclasses of InPlaceLabelMapFilter must take extra care in how they manage memory using (and perhaps overriding) the implementations of ReleaseInputs() and AllocateOutputs() provided here.
