Detailed Description

template<typename TInputPixelType, typename TOutputPixelType>
class itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >

Performs the Hough Transform to find 2D straight lines in a 2D image.

This filter derives from ImageToImageFilter. The input is an image, and all pixels above some threshold are those to be extracted. The output is the image of the accumulator. GetLines() returns a list of LinesSpatialObjects.

Lines are parameterized in the form: R = x*vcl_cos(Teta)+y*vcl_sin(Teta) where R is the perpendicular distance from the origin and Teta the angle with the normal.

The output is the accumulator array: -The first dimension (X) represents the distance R from the corner to the line -The second dimension (Y) represents the angle between the X axis and the normal to the line.

The size of the array depends on the AngleAxisSize that could be set (500 by default) for the angle axis. The distance axis depends on the size of the diagonal of the input image.

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
