Automatic detection of handwriting forgery
We investigated the detection of handwriting forgery by both human and machine. We obtained experimental handwriting data from subjects writing samples in their natural style and writing forgeries of other subjects’ handwriting. These handwriting samples were digitally scanned and stored in an image database. We investigated the ease of forging handwriting, and found that many subjects can succ...
متن کاملHandwriting changes under the effect of alcohol.
Document examiners are often faced with difficulties in evaluating handwriting by persons under the influence of alcohol. Although numerous articles are available on the subject of alcohol influence on handwriting quality, most of them were based on empirical data such as "few" or "increased", without any statistical evaluation. The aim of this research is to determine whether previous observat...
متن کاملAutomatic Detection Of Handwriting Forgery Using A Fractal Number Estimate Of Wrinkliness
We investigate the detection of handwriting forged by novices. To facilitate document examination it is important to develop an automated system to identify forgeries, or at least to identify those handwritings that are likely to be forged. Because forgers often carefully copy or trace genuine handwriting, we hypothesize that good forgeries – those that retain the shape and size of genuine writ...
متن کاملDetecting copy-move forgery under affine transforms for image forensics
In copy-move forgery, the copied region may be rotated and/or scaled to fit the scene better. Most of the existing methods fail when the region is subject to affine transforms. This paper presents a method for detecting this kind of image tampering based on circular pattern matching. The image is first filtered and divided into circular blocks. A rotation and scaling invariant feature is then e...
متن کاملOffline Handwriting Acquisition under Controlled and Uncontrolled Conditions
This paper gives a description of offline handwriting acquisition under controlled and uncontrolled conditions for research purposes. The data collection task is an underestimated part in the process of developing signature verification or handwriting identification systems. There is a continuous need for new, unpublished data to train and evaluate new algorithms. Handwriting samples that make ...
