Evaluating text-to-image matching using binary image selection (BISON)

Hu et al., ICCV Workshop 2019

Providing systems the ability to relate linguistic and visual content is one of the hallmarks of computer vision. Tasks such as text-based image retrieval and image captioning were designed to test this ability, but come with evaluation measures that have high variance or are difficult to interpret. We study an alternative task for systems that match text and images: given a text query, the system is asked to select the image that best matches the query from a pair of semantically similar images. The system's accuracy on this Binary Image SelectiON (BISON) task provides a robust and interpretable measure of its ability to match linguistic content with fine-grained visual structure. We gather a BISON dataset that complements the COCO dataset and use it to evaluate modern text-based image retrieval systems.

🔑 Key idea:

• They collected decoy COCO images for evaluation, reflecting text-to-image alignments.

🤔 Confidence:

• Low

✏️ Memo:

• This work used to be paralleled with FOIL (SheKhar et al., 2017).
