Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::PatchBasedDenoisingBaseImageFilter< TInputImage, TOutputImage >

Base class for patch-based denoising algorithms.

Implementation of a denoising filter that uses iterative non-local, or semi-local, weighted averaging of image patches for image denoising. The intensity at each pixel 'p' gets updated as a weighted average of intensities of a chosen subset of pixels from the image. The weights are derived using a kernel function on distances between (i) the patch around pixel p and (ii) the patches around the chosen subset of pixels in the image. This class of methods is motivated by texture-based image models and relies on nonparametric statistical modeling in the high-dimensional space of image patches. The choice of an appropriate kernel bandwidth parameter underlying nonparametric modeling can be important and may be estimated using cross-validation schemes.

Engineering issues underlying this class of methods include the choice of the patch size, the definition of a weighting mask on patches (e.g. to make patches more isotropic and less rectangular), the number of iterations over the image, the scheme for sampling patches from the image, and the weights balancing the regularization and data fidelity when the noise model is known.

This class of methods stems from the following two independent and simultaneous publications:

Suyash P. Awate, Ross T. Whitaker. Higher-Order Image Statistics for Unsupervised, Information-Theoretic, Adaptive, Image Filtering. IEEE Int. Conf. Computer Vision and Pattern Recognition (CVPR) 2005; (2):44-51.

Antoni Buades, Bartomeu Coll, Jean-Michel Morel. A Non-Local Algorithm for Image Denoising. IEEE Int. Conf. Computer Vision and Pattern Recognition (CVPR) 2005; (2):60-65.

While the former work considers the denoising algorithm as performing entropy reduction using nonparametric density estimation, the latter work treats it as nonparametric regression. Details underlying this class of methods appear in:

Suyash P. Awate, Ross T. Whitaker. Unsupervised, Information-Theoretic, Adaptive Image Filtering for Image Restoration. IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI) 2006; 28(3):364-376.

Antoni Buades, Bartomeu Coll, Jean-Michel Morel. Nonlocal Image and Movie Denoising. International Journal of Computer Vision (IJCV) 2008; 76(2):123-139.

This class provides the base software framework for implementing patch-based denoising methods for multi-dimensional and multi-channel (i.e. vector-valued pixels) images. This framework is multithreaded on shared-memory architectures. Multithreading is incorporated in, both, intensity-updates and bandwidth-estimation stages by subdividing the image domain and associating each sub-domain to a single thread for processing.

To prevent oversmoothing, this class provides the framework for including a data-fidelity term based on the knowledge of the noise model. The intensity updates are then treated as the sum of (1) the weighted smoothing updates (weighted by SmoothingWeight) and (2) the weighted fidelity updates (weighted by NoiseModelFidelityWeight) that prevent large deviations of the denoised image from the noisy data.

◆ GenerateData()

template<typename TInputImage , typename TOutputImage >
void itk::PatchBasedDenoisingBaseImageFilter< TInputImage, TOutputImage >::GenerateData ( )
overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.

◆ GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >
void itk::PatchBasedDenoisingBaseImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )
overrideprotectedvirtual

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierarchy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.
