Detailed Description
template<class TImage>
class itk::Statistics::ScalarImageToListAdaptor< TImage >
This class provides ListSampleBase interfaces to ITK Image.
After calling SetImage(Image::Pointer) method to plug in the image object, users can use Sample interfaces to access Image data. However, the resulting data are a list of measurement vectors. The type of data is measurement vector. For example, if the pixel type of Image object is STL vector< float > and each pixel has two different types of measurements, intensity and gradient magnitude, this adaptor has measurement vector of type ITK Point< float, 2>, and one element of the Point is intensity and the other is gradient magnitude.
There are two concepts of dimensions for this container. One is for Image object, and the other is for measurement vector dimension. Only when using ITK Index to access data, the former concept is applicable Otherwise, dimensions means dimensions of measurement vectors.
From the above example, there were two elements in a pixel and each pixel provides [] operator for accessing its elements. However, in many cases, The pixel might be a scalar value such as int or float. In this case, The pixel doesn't support [] operator. To deal with this problem, This class has two companion classes, ScalarAccessor and VectorAccessor. If the pixel type is a scalar type, then you don't have change the third template argument. If you have pixel type is vector one and supports [] operator, then replace third argument with VectorAccessor
