The VCR-Wiki Dataset for Visual Caption Restoration (VCR)
🏠 Paper | 👩🏻💻 GitHub | 🤗 Huggingface Datasets | 📏 Evaluation with lmms-eval
This is the official Hugging Face dataset for VCR-Wiki, a dataset for the Visual Caption Restoration (VCR) task.
VCR is designed to measure vision-language models' capability to accurately restore partially obscured texts using pixel-level hints within images. text-based processing becomes ineffective in VCR as accurate text restoration depends on the combined information from provided images, context, and subtle cues from the tiny exposed areas of masked texts.
We found that OCR and text-based processing become ineffective in VCR as accurate text restoration depends on the combined information from provided images, context, and subtle cues from the tiny exposed areas of masked texts. We develop a pipeline to generate synthetic images for the VCR task using image-caption pairs, with adjustable caption visibility to control the task difficulty. However, this task is generally easy for native speakers of the corresponding language. Initial results indicate that current vision-language models fall short compared to human performance on this task.

Model Evaluation
Method 1 (recommended): use the evaluation script
git clone https://github.com/tianyu-z/VCR.git
Open-source evaluation
We support open-source model_id:
["openbmb/MiniCPM-Llama3-V-2_5",
"OpenGVLab/InternVL-Chat-V1-5",
"internlm/internlm-xcomposer2-vl-7b",
"HuggingFaceM4/idefics2-8b",
"Qwen/Qwen-VL-Chat",
"THUDM/cogvlm2-llama3-chinese-chat-19B",
"THUDM/cogvlm2-llama3-chat-19B",
"echo840/Monkey-Chat",]
For the models not on list, they are not intergated with huggingface, please refer to their github repo to create the evaluation pipeline. Examples of the inference logic are in src/evaluation/inference.py
pip install -r requirements.txt
# We use HuggingFaceM4/idefics2-8b and vcr_wiki_en_easy as an example
# Inference from the VLMs and save the results to {model_id}_{difficulty}_{language}.json
cd src/evaluation
python3 inference.py --dataset_handler "vcr-org/VCR-wiki-en-easy-test" --model_id "HuggingFaceM4/idefics2-8b" --device "cuda" --dtype "bf16" --save_interval 50 --resume True
# Evaluate the results and save the evaluation metrics to {model_id}_{difficulty}_{language}_evaluation_result.json
python3 evaluation_metrics.py --model_id HuggingFaceM4/idefics2-8b --output_path . --json_filename "HuggingFaceM4_idefics2-8b_en_easy.json" --dataset_handler "vcr-org/VCR-wiki-en-easy-test"
# To get the mean score of all the `{model_id}_{difficulty}_{language}_evaluation_result.json` in `jsons_path` (and the std, confidence interval if `--bootstrap`) of the evaluation metrics
python3 gather_results.py --jsons_path .
Close-source evaluation
We provide the evaluation script for the close-source models in src/evaluation/closed_source_eval.py.
You need an API Key, a pre-saved testing dataset and specify the path of the data saving the paper
pip install -r requirements.txt
cd src/evaluation
# [download images to inference locally option 1] save the testing dataset to the path using script from huggingface
python3 save_image_from_dataset.py --output_path .
# [download images to inference locally option 2] save the testing dataset to the path using github repo
# use en-easy-test-500 as an example
git clone https://github.com/tianyu-z/VCR-wiki-en-easy-test-500.git
# specify your image path if you would like to inference using the image stored locally by --image_path "path_to_image", otherwise, the script will streaming the images from github repo
python3 closed_source_eval.py --model_id gpt4o --dataset_handler "VCR-wiki-en-easy-test-500" --api_key "Your_API_Key"
# Evaluate the results and save the evaluation metrics to {model_id}_{difficulty}_{language}_evaluation_result.json
python3 evaluation_metrics.py --model_id gpt4o --output_path . --json_filename "gpt4o_en_easy.json" --dataset_handler "vcr-org/VCR-wiki-en-easy-test-500"
# To get the mean score of all the `{model_id}_{difficulty}_{language}_evaluation_result.json` in `jsons_path` (and the std, confidence interval if `--bootstrap`) of the evaluation metrics
python3 gather_results.py --jsons_path .
Method 2: use lmms-eval framework
You may need to incorporate the inference method of your model if the lmms-eval framework does not support it. For details, please refer to here
pip install git+https://github.com/EvolvingLMMs-Lab/lmms-eval.git
# We use HuggingFaceM4/idefics2-8b and vcr_wiki_en_easy as an example
python3 -m accelerate.commands.launch --num_processes=8 -m lmms_eval --model idefics2 --model_args pretrained="HuggingFaceM4/idefics2-8b" --tasks vcr_wiki_en_easy --batch_size 1 --log_samples --log_samples_suffix HuggingFaceM4_idefics2-8b_vcr_wiki_en_easy --output_path ./logs/

Dataset Statistics
We show the statistics of the original VCR-Wiki dataset below:
Dataset Construction
Data Collection and Initial Filtering: The original data is collected from wikimedia/wit_base. Before constructing the dataset, we first filter out the instances with sensitive content, including NSFW and crime-related terms, to mitigate AI risk and biases.
N-gram selection: We first truncate the description of each entry to be less than 5 lines with our predefined font and size settings. We then tokenize the description for each entry with spaCy and randomly mask out 5-grams, where the masked 5-grams do not contain numbers, person names, religious or political groups, facilities, organizations, locations, dates and time labeled by spaCy, and the total masked token does not exceed 50% of the tokens in the caption.
Create text embedded in images: We create text embedded in images (TEI) for the description, resize its width to 300 pixels, and mask out the selected 5-grams with white rectangles. The size of the rectangle reflects the difficulty of the task: (1) in easy versions, the task is easy for native speakers but open-source OCR models almost always fail, and (2) in hard versions, the revealed part consists of only one to two pixels for the majority of letters or characters, yet the restoration task remains feasible for native speakers of the language.
Concatenate Images: We concatenate TEI with the main visual image (VI) to get the stacked image.
Second-round Filtering: We filter out all entries with no masked n-grams or have a height exceeding 900 pixels.
Data Fields
question_id:int64, the instance id in the current split.image:PIL.Image.Image, the original visual image (VI).stacked_image:PIL.Image.Image, the stacked VI+TEI image containing both the original visual image and the masked text embedded in image.only_id_image:PIL.Image.Image, the masked TEI image.caption:str, the unmasked original text presented in the TEI image.crossed_text:List[str], the masked n-grams in the current instance.
