Create a single image from an array of image.

The size of the output image is defined by:

width = n_horizontal * max(input[i].ncols()) height = (input.size() / n_horizontal) * max(input[i].nrows())

Returns:: a single image where all the input images are displayed as a mosaic.

Superpose two images.

Parameters:

`[in]`	input_	An image. Its value type must be convertible toward value::rgb8 thanks to a conversion operator or convert::from_to.
