How to build an invertible mapping between two variables whose dimensions are different ?

Maybe this is a stupid question, but I have been puzzled for quite a long time. In the image super-resolution task, the input and output have different dimensions. How to build an invertible mapping between them? I notice that you calculate the determinant of the Jacobian, so I thought the mapping here is strictly invertible?
