Reconstructing shredded documents through feature matching.
We describe a procedure for reconstructing documents that have been shredded by hand, a problem that often arises in forensics. The proposed method first applies a polygonal approximation in order to reduce the complexity of the boundaries and then extracts relevant features of the polygon to carry out the local reconstruction. In this way, the overall complexity can be dramatically reduced bec...

متن کاملFeature extraction and clustering for the computer-aided reconstruction of strip-cut shredded documents
bstract. We propose a solution for the computer-aided recontruction of strip-cut shredded documents. First of all, the visual conent of the strips is automatically extracted and represented by a umber of numerical features. Usually, the pieces of different pages ave been mixed. A grouping of the strips belonging to a same page s thus realized by means of a clustering operator, to ease the suces...
متن کاملSemi-Automatic Reconstruction of Cross-Cut Shredded Documents
We propose a new approach for cross-cut shredded document reconstruction and evaluate it on the DARPA Shredder Challenge dataset. We begin by pre-processing chads. A set of costs based on shape (gaps, overlaps, edge similarity), graphical content (ruling line alignment, text line alignment), and semantic content (character and letter combinations) is calculated and used to rank putative chad ma...
متن کاملA Modular Framework for the Automatic Reconstruction of Shredded Documents
The unshredding problem is of interest in various domains such as forensics, investigative sciences and archeology, and has therefore been approached in many different ways. This paper tries to bridge the gap between previous, disparate, efforts by proposing a modular, probabilistic, solution. Novel approaches to two of the independent subproblems are presented and shown to both have good theor...
