Oxia Palus

The Leonardeschi were a group of artists that worked in the studio of or under the influence Leonardo da Vinci, and 225 of their paintings were used to train the NVIDIA pix2pixHD model.

The Madonna of the Carnation diagram is one example of an application of the model in which the model can map an edgemap back to a painting.

Training the pix2pixHD model with a coarse-grained labeling semantic helps to guide the model in recognizing attributes such as hair and skin.

Oxia Palus manually co-registered (aligned) the x-ray of da Vinci's Virgin on the Rocks, from Imperial College London, with the x-ray trace produced by the National Gallery.

They then further manually edited the co-registered image, adding in missing trace components and labeling attributes such as skin, hair, and clothing.

Translucent colored labeling was used to prevent saturation of the underlying co-registered image.

Oxia Palus has a lofty mission: to uncover masterpieces lost to the ages using artificial intelligence. Learn how they translate from X-rays to paintings using datasets, standard image augmentations, holistically-nested edge detection, and other modern technologies to recreate Leonardo Da Vinci's Virgin of the Rocks.
