Converting INRimage simulation code to ITK¶
Image definition¶
The file heimdali/itkhelper.hxx defines the type of an image.
-
typedef float
Heimdali::PixelFloat¶
-
const unsigned int
Heimdali::ImageDimension¶ All images are 3-dimensional.
-
typedef itk::VectorImage<PixelFloat, ImageDimension>
Heimdali::ImageFloat¶
Images are 3-dimensionial, of size (nz, ny, nx).
Images contains nx * ny * nx pixels, and each pixel is a vector of nv value of type float.
| nz | Number of planes |
| ny | Number of rows |
| nx | Number of columns |
| nv | Number of values per pixel |
Internally, the image is stored in a continous block of memory, ie is a float*.
Building¶
Proving command line interface¶
Creating image¶
-
ImageFloat::Pointer
Heimdali::CreateImage(unsigned int nx, unsigned int ny, unsigned int nz, unsigned int nv)¶
itkhelper.hxx defines the CreateImage
function to create an image in the temporary program memory. It does not do any
persistant operation on the disk.
For example:
Heimdali::ImageFloat::Pointer image = Heimdali::CreateImage(5,5,5,2);
create a image of 3-dimensional image with 5 planes, 5 rows and 5 columns, where is value is a vector of 2 floats.
The following code:
Heimdali::ImageFloat::Pointer image = Heimdali::CreateImage(5,5);
create a image of 3-dimensional image with 1 planes, 5 rows and 5 columns, where is value is a vector of 1 float.
See the file createInputImage.cxx for a running example.
