From: Progressive compressive sensing of large images with multiscale deep learning reconstruction
The progressive sampling process. The image and its 2D Paley Ordered Hadamard samples below it, are illustrated in sequential order. The first stage starts at a low-resolution image. To increase the resolution, an appropriate additional set of ΔM compressive samples, (highlighted in color) is added to the 2D Hadamard transform of the image. The Hadamard samples ordered in 2D are illustrated below the multiscale images.
