Signature verification using shape descriptors and multiple neural networks

TLDR
This method is capable of verifying simple and skilled forgeries with a good performance and is based on signature shape descriptors such as the skeleton, upper and lower envelopes, and the high pressure region of the signatures.
Abstract
This paper presents an off-line signature verification system. The verification is based on signature shape descriptors such as the skeleton, upper and lower envelopes, and the high pressure region of the signatures. Multiple multilayer perceptron neural network modules cooperating in taking a verification decision via a fuzzy integral voter are used. This method is capable of verifying simple and skilled forgeries with a good performance.

Systems and methods for image recognition using graph-based pattern matching

Mark A. Walch
TL;DR: In this article, a method for creating a modeling structure for classifying objects in an image comprises converting an image into digital image data; using a processor, simplifying the digital images; using the processor, isolating objects in the simplified image data, creating graphs of the isolated objects, the graphs comprising vertices and edges; and finally, converting the graphs into representative graph data structures.

Systems and methods for biometric identification using handwriting recognition

Mark A. Walch
TL;DR: This article converted characters and a writing sample into mathematical graphs and used optical character recognition (OCR) techniques to identify these features in the handwriting sample so that drafts from two different samples can be aligned to compare to determine if the feature in the writing sample correlate with each other.

Forgery detection by local correspondence

TL;DR: This thesis approaches the off-line problem by establishing a local correspondence between a model and a questioned signature, and performs skilled forgery detection by examining the writer-dependent information embedded at the sub-stroke level and trying to capture unballistic motion and tremor information in each stroke segment, rather than as global statistics.
