And that, in the market so many of Leonardo that it requires a reference base?

I believe that if the radioactive isotopes could be deposited in the seeds of flax (which they obviously come from the air and earth), then the same is true for the poppy, walnut, etc.

The idea of recognizing "handwriting" of the artist or the "nature" of his stroke seems at first sight reasonable. But from this idea to its implementation on a computer - "a huge distance." Who will answer the question: what happens in the brain of an expert, when he looked at the picture, sets the "handwriting" of the artist? Here, I believe, not even one expert will be able to explain this to specialists in mathematics in pattern recognition. Yet these brain processes must "chew" your computer. The fact that it is necessary to formalize the recognition process to such an extent as to formulate the criteria for belonging to a particular picture of the artist or explicitly, or at least with quantified probabilities. What input should draw a mathematician in the programming of recognition of "handwriting"? Usually, in pattern recognition work with two-dimensional Fourier-images. But to base the study? individual strokes or pieces of paintings, or the whole picture? And the images of a physical quantity? Brightness or color? Or perhaps explore the three-dimensional image of the surface relief pattern (I omit the formidable complexity of writing such a relief to move it into digital form in a computer)? Theory and practice of computer pattern recognition, despite its complexity, this can work only with very basic facilities. So the idea is interesting and fruitful, but to obtain an acceptable result requires serious scientific cooperation specialist art historians and mathematicians, as applied scientists as well as "clean". This is a matter for the future, but perhaps not very distant.

Sandro, is called - examination by the method Morelli, already used in the U.S. - the company called "Art Experts Inc.", It has opened a branch in Moscow, the representative is here on the forum. They make high-resolution photo and experts on the photo give their opinion ... I think a European firm, and the name of another. It looks like this: Every artist has some writing techniques that are specific to this painter. And these tricks are repeated in all his paintings, preparatory drawings and so d.Skopirovat those elusive subtleties of eye-impossible, Comp. immediately sees the same kopiyu.Esli not mistaken, the database Europeans had not yet finished, and when it begins to work is unknown, but SKORO.YA think so !!!!!

iron horse is coming to replace peasant horse. Uninterrupted production of Soviet vehicles. Crash defeat on bad roads and sloppiness. (c)

Honored method pro Morelli: http://www.oldandsold.com/articles03/article1282.shtml. Actually, this is not what I thought, that no recognition of images (as understood in Applied Mathematics). Incidentally, the article itself was published in 1913. Here is a small excerpt.

"With a strong magnifying glass, he (judge) will hold the final test. He knows that Leonardo was a lefty, in the drawings of Leonardo's pencil or pen strokes are from left to right. The pasty written fragments, or coloring bodies, finely drawn on a test pattern, magnifier can be seen strokes, going from right to left. This was written by some right-handed. "No," said the expert, "it is not by Leonardo da Vinci." [There is a certain] features characteristic of Luini and Bramantino. Then he studied painting as a possible Luini, but then what he finds is characterized Bramantino. He opens the relevant page of the book Morelli, which contain copies of images of hands and ears with authentic paintings and drawings Bramantino. His hands always stretched out, with thin, wrinkled in straightening the fingers, two of which are connected, while others aside. The ears are always extended, moreover, the lobes developed, almost peaked. The picture on the easel shows all these features. "Bramantino This solves the expert."
Next is something about the analysis of the structure of the canvas or board, especially about mounting canvas on stretcher, etc.

I did not see anything revolutionary, especially for 2009. Moreover, it will be very articulate not just in Pascal or C is such a thing as a "elongated ears.

In essence, this method can, in principle, the ensuing program, similar to plants, which offers consistently answer questions like: 1) Leaves
green? (yes, no). Let's say yes. 2) The flowers are red? (yes, no). Suppose not. 3) The flowers are blue? (yes, no). Suppose yes. 4) petals 5? etc. In the end you get the answer "Forget-Me." So it is with plants. But as with the artists? What if the same would not have written Bramantino Madonna, whom he had not seen and attributed it to the possession of elongated ears, and, for example, a portrait of a real person with a thick, short hands and short ears without lobes? Could an expert on the book cited Morelli, then the sentence "This is NOT Bramantino? Question: And what are "handwriting" of the artist? Can anyone answer this question so that the answer would be unambiguously clear round ... non-specialist in the painting? For computer - metal is that the man tells it to do, then (and only then!) And he will do, intuition is alien to him ...

I brought only the most famous primer.no take the same-mentioned Bellini (unfortunately no photos and then I'm not sure that its publication would have been ethically in relation to the owner). This work was in his family more 200let, in the 18 century according to the rococo tastes just changed the color of clothes and rewrote the sky, in the 19. when you were in vogue nazareytsy touched faces, and I'm not sure that the withdrawal of these records are not found to something else, because the work of more than 500 years, while it is recognized podlinnikom.A now Imagine what it will recognize and evaluate the computer so that "Mensur Zoili, and what response it will give and by what criteria?

Why climb into the depths of centuries. This method is suitable for relatively young, not restored paintings, with a threshold in the area in 1945, which in fact can be determined by other methods.

Hopefully, modern restorers smarter than those that were in the 18-19 centuries, and now, with the necessary "conservation" (restoration) will not change facial expressions and styles of clothing, regardless of whether United Russia in power or someone else.

now in the restoration (at least in the domestic), the main principle is do no harm, no records, only toning within utrat.A about "smarter" not very confident.

I had a view of the method, about which you write, which is used for the examination of paintings are not computer experts and alive.
I agree, the new is well forgotten past, although this method has never been forgotten, and is used by experts from Beginning of the .20-century in a comprehensive study.
