Comparison of selected atomic-resolution images obtained using TCS-DL and JPEG compression in Figure 2

(A–C) 5^th raw images, reconstructed images using TCS-DL and JPEG compression.

(D–F) Fast Fourier transforms of the images in (A–C). Bragg spots corresponding to the (004) planes are indicated by the arrows in (D and E). Information loss is identified in the JPEG-compressed image (F) as the Bragg spots corresponding to (004) planes are not resolved.

(G–I) 25^th raw images, reconstructed images using TCS-DL and JPEG compression. Compared to the raw image (G), more surface details are observed in the TCS-DL-processed image (H) due to the edge enhancement. In contrast, deteriorated image quality such as edge blurring is identified in the JPEG-compressed image (I).
