Johnson	On the Utility of Spectral-Maximum-Based Automated Thread Counting from X-Radiographs of Paintings on Canvas	2011	11	.pdf	application/pdf	7139	595	67	thread counting relies upon the topography of the twodimensional Fourier transform of the X-radiograph. This paper establishes that the two-dimensional Fourier transform, spectral-maximum-based extraction of thread density appears suited to automatic thread counting from scanned X-radiographs of paintings for a range of European painters from the suggest that recently developed spectral-maximum-based thread counting algorithms are sufficiently sophisticated to support major used by some artists require a more refined approach to automated thread counting than a simple spectral-maximum-based scheme.
