Figure 6: Reconstruction of sub-pixel patterns from LDIH images.
From: Sparsity-Based Pixel Super Resolution for Lens-Free Digital In-line Holography
(A) The sparsity algorithm was tested on images acquired with a LDIH system, which showed sub-pixel resolution enhancement. The reconstructed images were compared to reference images acquired by a bright field microscope with a 100x objective. (B) Schema of object and line profiles from LDIH show improved resolution after applying the sparsity algorithm.
