The analysis of the results shows the considered theories lead to impressions that can only approximately explain how the image on the Shroud was formed. The impressions on the Shroud are therefore the result of a scientific process that still has not been neither completely, nor empirically, nor theorically explained. Anyway, results do not contrast with but rather adapt to the theory that the image … Continua a leggere »

Vapor theory

First advanced by Paul Vignon in 1902 it assumes the image was caused by the projection of body vapours. The phenomenon would result from the sweat urea decomposing in ammonium carbonate then becoming carbon dioxide, water and ammonia; the next chemical reaction with aloe and myrrh, used for the burial, would produce a colorimetric variation. This theory was criticized a lot; the main objections are: … Continua a leggere »


Information technology has highlighted a very important intrinsic feature of the image on the Shroud: the three dimensional feature. The fact that some details came out of three dimensional processing precludes any possibility there was a manual contribution to the image formation; as a matter of fact, it is impossible to have included details that, even if invisible to the naked eye, they become visible … Continua a leggere »

For blind people

The idea of putting the Shroud disturbing signs of suffering at disposal of blind people rose from a pastoral concern: is it possible to make them personally and directly meet the Shroud without the human word intervention? Father Giuseppe Chicco, the Turin ecclesiastical and consultant of the Apostolic Movement of the Blind, thought it impossible on the face of it. During the 2000 exposition the … Continua a leggere »

Fourier transform

This is another research tool to obtain important results in the study of the Shroud. In mathematics it is a very important image processing tool to reach results in particular interest domains no other way reachable with the tools used in the spatial domain so far. It works transforming an image from the spatial to the frequency domain that, to simplify, can be considered as … Continua a leggere »

Shroud and icons

The human face of the Man of the Shroud allows to verify, from the computer studies perspective, the correspondence the historic-iconographic research claims between this face and the most important icons representing Christ. In order to compare them in the most direct way, it was obtained a straight and frontal representation of the face in fig.6 by a rotoscalamento transformation which led to fig. 13. … Continua a leggere »

A three dimensional image

The study of three dimensional images began with image processing by artificial satellites; in the ‘70s NASA scientists succeeded in obtaining three dimensional pictures of celestial bodies since their distance allows to perceive their images’ different brightness. On the contrary, there is no three dimensional information in ordinary pictures since the photographic process does not allow to establish a direct connection between the objects and … Continua a leggere »

The Shroud face

The several wounds on the three dimensional image of the face scar its beauty making interpret its physiognomy as belonging to a not very young man whereas historians estimate Christ was 35-40 years old. On the other end, its high quality enables to glimpse the natural features of the Man of the Shroud. It was considered therefore really important to clean wounds and bloodstains. The … Continua a leggere »
