Supplementary Visual Results for 'Assessing GAN Super-Resolution in Grasslands: The Role of Spatial Heterogeneity and Textural Complexity

This repository provides the complete set of visual comparisons used to evaluate super-resolution performance in heterogeneous grassland ecosystems. It includes downscaled outputs from SRGAN, ESRGAN, and bicubic interpolation across all test tiles under three downscaling strategy frameworks: intra-sensor, cross-sensor, and intra-to-cross generalization.

The dataset is organized according to NDVI-based quartiles, structure-based clusters, and entropy-based quartiles, enabling detailed inspection of model behavior across gradients of vegetation condition, spatial structure, and textural complexity. These materials complement the figures presented in the manuscript and provide full transparency of the evaluation results.
