Even Georgia O Keeffe was aware of the blisters that were hitting a pin and a # 39; hit the surface of her pictures. For decades, conservationists and pupils embraced these small deficiencies were sand grains, which were taken from the desert of New Mexico where O & Keeffe had; live and work. But when the initiatives started to grow, spread and finally left, people would moving from your worries.

A multi-disciplinary team from the Northwestern University and the Georgia O Keeffe Museum in Santa Fe, New Mexico have now shown that the pain is a strange pain: and it's a metal soap ; in the micro-media, a & n; Comes from a chemical migration between the metal strings and the salted acids commonly used as a paint link.

Encouraged by the research, the team created a new device, a mobile device capable of mapping and exploring artwork easily and effortlessly. The tool allows researchers to look carefully at the initiatives to better understand what the conditions will be; make the jobs grow, and # 39; bend or break.

"Free free car packs are included within paint links to lead parts and zinc," said Marc Walton, research professor of materials and engineering science at McCormick's Engineering School, the head of the survey. "These soaps of metal started together, pushing the surface of the paint and creating something that looks like acne."

"If we can easily customize, identify and record these soap operations and again with very little cost to the museum, we can look at them while they are improving, "said Oliver Cossairt, a professor related to a computer in McCormick's technological development. "This could help keepers criticize health and order the ability to handle damaged artworks."

Walton, co-director of the Center for Scientific Science in the Arts, co-operation between Northwestern and Art Art Chicago, reflects on research findings and technology at 16 American Press Release Press Release for Science (AAAS) annual meeting in Washington, DC

The guidance, "Art Conservation Leverages Advanced Scientific Knowhow," will be held at 9 a.m. EST at Balcony A of the Marriott Wardman Park.

Cossairt will deliver the research at the next day's scientific session. His speech, "Diagnosing a Paint Disease with Computer Science: Case of Georgia O Keeffe," is part of the session "Medicine, Computing and Art: Learning through Technology" (8 to 9:30 PM EST on February 17, room 2, Marriott Wardman Park).

Serious disease

Almost all photographs of Georgia O Keeffe are doing a bit harming by & # 39; metal soap production. Although some of the "acne" cases are at an early stage of development and can only be seen with ultraviolet images, others are more advanced and can be seen with the stunning eye. Keepers have restored some of the pictures where the damage is more likely, but the campaigns are still coming back.

"The drop-down rate is one of the most important issues in the study," said Dale Kronkright, a conservation leader at the Georgia O & Keeffe Museum. "There seems to be a little correlation between the number of journeys that the pictures have traveled to public exhibitions and the size and quality of the breach of the surface. Further than the pictures of travel, the more likely the initiatives are more bigger and bigger. "

Walton and his team in the Center for Scientific Science in the Arts explore how quickly the process can be progressed by doing so. Removal of metal soap dropping down in amazing paintings. There are also decades of detail from the Georgia O & Keeffe Museum, which records the different environments that have received different pieces when they were; travel and presentation.

"After we have been able to understand what kind of environmental situation they have been, how much of a relative depth, what type of temperature, whether they have been in direct light, we can order a special environment with specific conditions that allow them to survive long-term artwork, "said Walton.

These conclusions can be applied more widely because of the OKeeffe excellence. Destructive soap bodies are oil painting from all times.

"If we can solve this problem, we preserve our cultural heritage for future generations," said Walton.

From science fiction to non-fiction

Cossairt is often launching his handset on Star Trek. "The showmakers will remember their favorite characters that use the pocket tool to identify areas that are unfamiliar, to analyze unnatural objects and to diagnose diseases .

Instead of human health (or community) assessment, the machine developed in the Healthcare laboratory can be proven. It will use the LCD display and a camera is now available on smartphones and recordings. With a simple wave over a painted surface, the application quickly sets out a detailed surface structure, 3-D of work, or a matrix. It can then remove the color of the work to help researchers identify any movement in the shape of a non-surface surface; come from scorpion or canvas worms.

"It's similar to the" tricorder "toolkit," said Cossairt. "It can give you a really accurate measure but also something you can pull from your pocket."

The app will use the light of a light from a mobile device – both LEDs or LCD images – a & # 39; show a light on the surface of the painter and accept that reflection with a & # 39; camera. The image is then handled by existing algorithms that were developed at Northwestern by Aggelos Katsaggelos to get surface form information.

"We will collect a lot of data efficiently, successfully, but then the data needs to be processed," said Katsaggelos, Professor Joseph Cummings, Electric Engineering and Computing at McCormick. "The technology using tools is learning to differentiate whether it's a soap or something similar to breaking a brushes. Then, for the campaigns, we draw statistics – the density, size and shape. "

Compare this handheld and the great, difficult equipment needed to design a medical map. The main method of operation, called reflectance transformation images, is a & # 39; It requires a large globe of a number of light bubbles and a expensive situation. There are very few museums that invest in buying and selling. keep up instruments like this

"We're trying to make it simpler, much cheaper and easier to make it easier to stop the use," said Cossairt.

The research is supported by the National Endowment for Humanities.
