Article Title: Tomographic Collection of Block-Based Sparse STEM Images: Practical Implementation and Impact on the Quality of the 3D Reconstructed Volume
doi: 10.3390/ma12142281
Figure Lengend Snippet: Collection of a sparse scanning transmission electron microscopy (STEM) image, inpainting reconstruction and comparison with ground truth. ( A ) Sparse STEM image downsampled to 12.5% using 512 blocks of 16 × 4 pixels. The white background corresponds to uncollected pixels. ( B ) Sparse image A after inpainting reconstruction. ( C ) Ground truth fully-collected STEM image of the very same ROI on the grid. Scale bar is 200 nm. The three subfigures have the same scale.
Article Snippet: After collection of the whole tilt-series, block-based sparse images were reconstructed in Matlab using 250 iterations of the inpainting algorithm developed by Garcia [ , ].
