Some researchers use these specific filenames in benchmarks for Image Matching across Wide Baselines to test how models handle different perspectives of the same object.
The study highlights that OCR-free models perform better when queries involve visual, non-text elements, and that models pre-trained on image-text contrastive learning tasks (like CLIP ) show superior accuracy. Other Potential Matches 39l.jpg
This paper introduces a first-of-its-kind benchmark for fine-grained document retrieval in natural scenes. It includes a dataset of 41,000 document images (where files like 39l.jpg are part of the image corpus) paired with over 200,000 queries . Some researchers use these specific filenames in benchmarks
Recent papers like Monkey: Image Resolution and Text Label Are Important Things for CVPR 2024 use high-resolution image sets to improve visual understanding in Large Language Models. It includes a dataset of 41,000 document images
