Fig. 6: Example output of AdaSlide on a sample from the TCGA-BRCA dataset.
From: Adaptive compression framework for giga-pixel whole slide images
Compression and information-preservation performance evaluated on the TCGA-BRCA sample TCGA-OL-A66K (original WSI size: 3.17 GB) at 20× magnification. A Original WSI with pathologist-annotated tumor regions. B CDA compression probability heatmap. Red regions indicate keep actions; blue regions indicate compress actions. Tumor regions exhibit a higher tendency for keep actions (AUROC = 0.6288). The overall compression ratio was 21.74%. C Representative examples of four regions based on information disequilibrium. Red borders: ESRGAN-reconstructed images; blue borders: original images. Clinically informative regions correspond to tumor areas. D Storage requirements by image format. The hybrid strategy required an average of 11.19% of the original WSI size. Exact numerical values and statistics are provided in the Source Data file.
