Algorithms for Old Master painting canvas thread counting from x-rays
2008
2008 42nd Asilomar Conference on Signals, Systems and Computers
Preserved Fulltext
Because of the way paintings were commonly prepared and preserved, the threads in the horizontal and vertical directions in the canvas support can be counted from x-ray images of the painting. ...
The task of determining the weave density in the canvas support of Old Master paintings is introduced as a period extraction problem. ...
ACKNOWLEDGEMENTS The authors would like to thank the Van Gogh Museum for making the digital x-ray images available. ...

Thread counting algorithms seek to determine the vertical and horizontal weave densities of the canvas underlying a painting. X-ray images of a painting serve as the raw data. ...
The actual painting serves as an additive signal that only distracts from the thread-counting process. The algorithm employs a variant of short-time Fourier analysis to the image domain. ...
THE CANVAS THREAD COUNTING PROBLEM To investigate the history and authenticity of paintings by the great masters, signal processing algorithms can provide new insights [1, 2] . ...

Our work develops algorithms to examine x-ray images of paintings, not to analyze the artist's brushstrokes but to characterize the weave of the canvas that supports the painting. ...
In examining paintings, art historians use a wide variety of physico-chemical methods to determine, for example, the paints, the ground (canvas primer) and any underdrawing the artist used. ...
ACKNOWLEDGMENTS The authors thank the many museums that contributed to the database of scanned x-ray images of van Gogh's paintings. ...
