Fourier Transform in Painting Authentication

Authenticating paintings has always been a problem in the art world especially during auctions. Usually, they rely on the opinion of art historians who specialize in that artist to determine a painting’s authenticity. Now, with Fourier transform, they are able to analyze the painting with certainty. After scanning the picture for a digital image, they convert it to a Fourier transform to filter useful information that would help them identify the painting’s elements. They are able to analyze the painting’s brushstrokes and compare it to an original artwork to determine its authenticity.
