# The VCR-Wiki Dataset for Visual Caption Restoration (VCR)
|

๐ [Paper](https://arxiv.org/abs/2406.06462) | ๐ฉ๐ปโ๐ป [GitHub](https://github.com/tianyu-z/vcr) | ๐ค [Huggingface Datasets](https://huggingface.co/vcr-org) | ๐ [Evaluation with lmms-eval](https://github.com/EvolvingLMMs-Lab/lmms-eval)
|
52 |

|
53 |
+
This is the official Hugging Face dataset for VCR-Wiki, a dataset for the [Visual Caption Restoration (VCR)](https://arxiv.org/abs/2406.06462) task.
|
54 |
+
|
55 |
+
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.

|
59 |
+
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.

## Dataset Statistics
|
109 |
+
|
110 |
+
We show the statistics of the original VCR-Wiki dataset below:
|
111 |
+

112 |

|

114 |
+
## Dataset Construction
|
115 |
+
|
116 |
+
![image/png](https://raw.githubusercontent.com/tianyu-z/VCR/main/assets/vcr_pipeline.png)
|
117 |
+
|
118 |
+
* **Data Collection and Initial Filtering**: The original data is collected from [wikimedia/wit_base](https://huggingface.co/datasets/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.
|
119 |
+
|
120 |
+
* **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.
|
121 |
+
|
122 |
+
* **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.
|
123 |
+
|
124 |
+
* **Concatenate Images**: We concatenate TEI with the main visual image (VI) to get the stacked image.
|
125 |
+
|
126 |
+
* **Second-round Filtering**: We filter out all entries with no masked n-grams or have a height exceeding 900 pixels.
|
127 |
+
|
128 |
+
## Data Fields
|
129 |
+
|
130 |
+
* `question_id`: `int64`, the instance id in the current split.
|
131 |
+
* `image`: `PIL.Image.Image`, the original visual image (VI).
|
132 |
+
* `stacked_image`: `PIL.Image.Image`, the stacked VI+TEI image containing both the original visual image and the masked text embedded in image.
|
133 |
+
* `only_id_image`: `PIL.Image.Image`, the masked TEI image.
|
134 |
+
* `caption`: `str`, the unmasked original text presented in the TEI image.
|
135 |
+
* `crossed_text`: `List[str]`, the masked n-grams in the current instance.
