Comparison of the simulation results with the state-of-the-art techniques shows improved precision, recall, and F-Measure values for the proposed technique. Simulations are performed on images taken from three datasets in which copy-move area was plain,compressed, rotated, scaled and pasted multiple times. Afterwards, linear spectral clustering is applied for better forgery localization. Then, morphological processing and structural similarity index are used to refine matches. Afterwards, keypoints are matched using generalized 2 n d nearest neighbour. Second, BRIEF features with FAST descriptors are used to detect keypoints from missing regions (i.e. First, SIFT is used to detect keypoints in smooth regions. To solve these issues, the paper presents a two step keypoint based forgery detection technique. Most of the existing copy-move forgery techniques fail to detect forgery in smooth areas, forgery regions which are pasted multiple times or pasted after rotation and scaling.

At Kompani Risk & Insurance Solutions, Inc. Purchasing a valued work of art can be a risky endeavor. Taking a look under the frame may be necessary for proper examination. Another thing to look for are discernible plate marks and impressions which should be visible around the image. If the print only has the plate signature, chances are it’s a reproduction print. When checking for the authenticity of a print, an artist’s signature should be noted on it. Edition numbers are not an absolute indication of authenticity, although it is an important first step in the process. When an artist makes prints, each one is created from a plate and is technically considered a unique work of art even though it is produced in multiples, known as an “edition.” After obtaining the print’s edition number, appraisers usually look to catalogs to confirm the numbers match the known number. There are times when even the documents themselves can be forgeries, but a reputable appraisal company will check to ensure their veracity.īy contrast, original prints are produced by the artist or a professional assistant for the purpose of creating a limited number of images. A gallery label, a signed certificate of authenticity, an artistic statement discussing the piece, receipts, an expert appraisal, or a history of ownership, leaves no doubt that an art piece is genuine. By contrast, even with high quality inkjet printers used to make giclée copies, appraisers can discover under close examination the dot matrix pattern used.įinally, the painting’s provenance-the documentation that confirms a work of art’s authenticity-is a useful method to use. With original paintings one can see and feel the texture of the paint and the overlapping colors used. In a forgery there are subtle differences-such as a detailed line that is rendered blurry-that can identify a potential fraud.Īnother method is eyeing the canvas. One can also examine the artist’s style and ability and compare it to other paintings by the same artist. The most reliable method is identifying the signature, which can be ascertained by referencing books and periodicals that contain the artist’s signature. When it comes to authenticating an oil painting, there are several factors to look out for-signatures, artistic styles and abilities, hand-painted versus machine-made, canvases, and provenance. As this month’s edition of Claims Magazine presents, it takes expert discernment to be absolutely certain of the authenticity of fine art. And while an authentic art work can be worth millions of dollars, a well-duplicated forgery is worthless in comparison, so the risk of making a costly error looms large. Appraising fine art is an art itself, and can prove to be one of the most daunting-albeit, intriguing-categories in property insurance.
