CEDAR-FOX
This is a software system for forensic comparison of handwriting. It was developed at CEDAR, the Center of Excellence for Document Analysis and Recognition at the University at Buffalo. CEDAR-FOX has capabilities for interaction with the questioned document examiner to go through processing steps such as extracting regions of interest from a scanned document, determining lines and words of text, recognize textual elements. The final goal is to compare two samples of writing to determine the log-likelihood ratio under the prosecution and defense hypotheses. It can also be used to compare signature samples. The software, which is protected by a United States Patent S. N. Srihari, et.alMethod and Apparatus for analyzing and/or comparing handwritten or Biometric Samples United States patent No. 7,580,551, Aug 29,2009. can be licensed from Cedartech, Inc. Details Writer verification is the task to determine whether two handwritten samples are written by the same writer or not. It is ...

Center Of Excellence For Document Analysis And Recognition
The Center of Excellence for Document Analysis and Recognition (CEDAR) is a research laboratory at the University at Buffalo, State University of New York. The center was established with funding from the United States Postal Service and National Institute of Justice. CEDAR was formalized by the United States Postal Service by Postmaster General Anthony Frank in 1991.The primary goal of CEDAR was to conduct research and development for developing software useful for the automation of postal sorting equipment. Work at CEDAR, with Sargur Srihari as principal investigator, led to the first handwritten address interpretation system in the world.S. N. Srihari and E. J.

Questioned Document Examination
In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court. Overviews Many QDE involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship. A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sargur Srihari
Sargur Narasimhamurthy Srihari (May 7, 1949 – March 8, 2022) was an Indian and American computer scientist and educator who made contributions to the field of pattern recognition. The principal impact of his work has been in handwritten address reading systems and in computer forensics. He was a SUNY Distinguished Professor in the School of Engineering and Applied Sciences at the University at Buffalo, Buffalo, New York, USA. Early life and education Srihari received undergraduate degrees in Science and in Electrical Communication Engineering from the National College of Bangalore University and the Indian Institute of Science in Bangalore respectively. He received Master's and Doctoral degrees in Computer and Information Science from Ohio State University, Columbus. Career CEDAR Srihari is the founding director of Center of Excellence for Document Analysis and Recognition (CEDAR) which was established with support from the United States Postal Service.

Handwriting Recognition
Handwriting recognition (HWR), also known as handwritten text recognition (HTR), is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning (optical character recognition) or intelligent word recognition. Alternatively, the movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface, a generally easier task as there are more clues available. A handwriting recognition system handles formatting, performs correct segmentation into characters, and finds the most plausible words. Offline recognition Offline handwriting recognition involves the automatic conversion of text in an image into letter codes that are usable within computer and text-processing applications. The data obtained by this form is regarded as a static representation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Similarity Measure
In statistics and related fields, a similarity measure or similarity function or similarity metric is a real-valued function that quantifies the similarity between two objects. Although no single definition of a similarity exists, usually such measures are in some sense the inverse of distance metrics: they take on large values for similar objects and either zero or a negative value for very dissimilar objects. Though, in more broad terms, a similarity function may also satisfy metric axioms. Cosine similarity is a commonly used similarity measure for real-valued vectors, used in (among other fields) information retrieval to score the similarity of documents in the vector space model. In machine learning, common kernel functions such as the RBF kernel can be viewed as similarity functions. Use in clustering In spectral clustering, a similarity, or affinity, measure is used to transform data to overcome difficulties related to lack of convexity in the shape of the data distribut ...
