Clone

Include <mln/core/algorithm/clone.hpp>

InputImage{I}
image_concrete_t<I> clone(I src)

Clone the values from the source image src to a destination image which is automatically deduced as the concrete type of the input. This primitive is directed at:

• creating a temporary image with the same values than the input

• saving the evaluation of a view

This is equivalent to the following code:

mln::image_concrete_t<InputImage> dst = src.concretize();
mln::copy(src, dst);

The source and destination images should not alias. This function has a parallel implementation, see following section for an example.

Parameters:

src – The source image

Template Parameters:

InputImage – A model of InputImage

Returns:

The concrete image of src with the same values

Examples

1. Eval an image view:

   mln::image2d<mln::uint8> f = ...;
   float mean = 10.f;
   float stdv = 2.f;
   auto g = (f - mean) / stdv;
   mln::image2d<float> f2 = mln::clone(g); // Evaluation of the view
   

2. Using parallel clone to evaluate an image view:

   mln::image2d<mln::uint8> f = ...;
   float mean = 10.f;
   float stdv = 2.f;
   auto g = (f - mean) / stdv;
   mln::image2d<float> f2 = mln::parallel::clone(g); // Evaluation of the view
   

Complexity

Linear in the number of pixels.
