The WebTattoo dataset was built based on Images from Internet, which contains about 300K tattoo images which are supposed to be the distracter background images in large-scale tattoo retrieval tasks. We additionally provided the tattoo bounding boxes for the tattoo images from the public-domain flickr and demsi datasets. We also provided 300 tattoo sketches with their mated tattoo photos for sketch-based tattoo retrieval task. The figure below gives a few examples of the tattoos and tattoo sketches.
2. Evaluation Protocol
For tattoo localization task, we recommend using FPPI-Recall and mAP to evaluate the performance. For tattoo retrieval and sketch-based tattoo retrieval tasks, we recommend using the PR curve to evaluate the performance.
