Frequently Asked Questions

The authentication fees vary depending on the amount of information you wish to receive. We currently offer two options: an AI evaluation without report, which means that you will only receive the result (positive/ negative, with the corresponding probability), or an AI evaluation with report, which includes extensive information about the analysis, data used for training the AI, heat map depicting the most important features for the AI’s decision etc. An AI evaluation without report costs between 600 CHF and 1000 CHF, whereas the price for a full report ranges between 3’000 CHF and 5’000 CHF.

If you are submitting at least 5 images of artworks for authentication, please write us on office@art-recognition.com to inquire about reductions. We will be happy to offer you a package tailored to your needs.

The price depends on how difficult it is to get enough images, or whether there is disagreement among experts as to which paintings are to be regarded as authentic. Ultimately, it is also decisive how often an artist has changed his style, whether there have been a lot of restorations or whether an artist had his apprentices finish an artwork.

Definitely. Please also provide additional information such as the style, period, and a short list containing the most probable candidates.

No. The Art Recognition AI System can handle any artist, provided there are enough original artworks by that artist to train on.

Certainly. Our AI produces accurate results even for the artists which significantly changed their style across their careers, such as for example Cézanne. To be able to capture the different styles, we make sure to include a sufficient number of images from each period.

Indeed, the Art Recognition AI System can deal with this situation. The unique brushstroke of an artist spans across all styles, also on periods which contain less works. Therefore, if your artwork is an original piece by the assumed artist, the brushstroke will be recognized.

Art Recognition has access to more than one million high resolution images.

Normally a dataset of around 200 images is enough to produce accurate results. For the more complex artists, this number should be higher in order to better capture the variations in style. We also augment the dataset by splitting the images into smaller patches, and zooming into them in order to capture the finer details.

We use images documented in Catalogue Raisonnés and embed the opinion of art experts whenever possible, in order to assemble training dataset of high quality.

Normally we deliver the AI Report and Certificate within 7 days. If we need longer, we inform you right away.

Absolutely. Please make sure that the photo is upfront and with no shadows coming from lamps or other objects.
