imref2d
Reference 2-D image to world coordinates
Description
An imref2d
object stores the relationship between the
intrinsic coordinates anchored to the rows and columns of a 2-D image and the spatial
location of the same row and column locations in a world coordinate
system.
The image is sampled regularly in the planar world-x and world-y coordinate system such that intrinsic-x values align with world-x values, and intrinsic-y values align with world-y values. The resolution in each dimension can be different.
Creation
You can create an imref2d
object in these ways.
affineOutputView
— Store the spatial extent of an image that is warped by a 2-D affine geometric transformation.The
imref2d
function described here.
Syntax
Description
creates an

also specifies the spatial extent of a single pixel in the x-
and y-dimensions in the world coordinate system.R
