Art tagging or geo-coding makes it possible to identify both people and places. Based on a name, a place, a coordinate transformation can be carried out by means of the search engine Pelias. By means of the image matching program of google, a comparison can be made, for example, of a painting with a real place or person. Correspondingly, a facial outline of a person can be made with the database in order to be able to identify the person.
In the following example, the location of the micro-image as well as the direction of gaze can be determined by local assignment.
A comparison of the motif with old engravings led to the identification of the location. The image shows the ruins of Trancaville Castle at the mouth of the Seine near Le Havre on the English Channel. In the meantime, the waters of the Seine no longer reach as far as the site as depicted in the engraving of that time. This could also be a landscape depiction by A. Perregeaux or J. Dresch.
