The long alphanumeric string ( 491615812a62cdcd... ) is a hash typically generated by automated dataset loaders (like those in PyTorch or TensorFlow environments) or specific repositories on platforms like Kaggle or GitHub to ensure file integrity.
Specifically, this image corresponds to the image, which is the 29th image (IMG_29) in the expanded or internal numbering of the Set14 collection. The paper that originally introduced and popularized this dataset for super-resolution evaluation is: Set_41_IMG_29_491615812a62cdcd56c55b1e29d25768.jpg

While often referred to as Set14 , it is an extension of the earlier Set5 dataset. It consists of 14 images with varying textures and structures used to test how well algorithms can upscale images while preserving sharp edges.
You will see this image and its associated paper cited in almost every major Super-Resolution study, including those for SRCNN , VDSR , and EDSR , as it serves as a standard for comparing Peak Signal-to-Noise Ratio ( PSNR ) and Structural Similarity Index ( SSIM ) values.
