This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A segmentation based courtesy amount recognition (CAR) system is presented in this thesis. This system consists of four modules, which are preprocessing, segmentation, recognition and syntactical analysis. The noise is first removed in the preprocessing module. Then, the segmentation module seeks to extract characters (digits, punctuation marks and so on) from the numeral strings. The recognition module aims at classifying each pattern into one of the ten numerals ('0'-'9') and double zeros ('00'), rejecting ambiguous patterns. Finally, the syntactical analysis module parses the recognition results to provide an acceptable courtesy amount. Two sets of features, shape features and spatial features, are developed to locate the punctuation marks. In addition, a hypotheses-then-verification approach for segmentation of the numeral strings is introduced. The emphasis is on finding all possible segmentation hypotheses and then verify them. A two-level segmentation module is proposed, namely the global segmentation level and the local segmentation level. At the global segmentation level, the intent is to find the potential broken numerals and group them together. On the contrary, the local segmentation level seeks to split the touching digits. Two classifiers are combined into the recognition module. The isolated digit classifier divides the input patterns into ten numerals ('0'-'9'), while the holistic double zeros classifier intends to recognize the cursive and touching double zeros as an atomic symbol. The proposed courtesy amount recognition system has been trained on the database of CENPARMI checks and tested on the database of real checks. The system reads 66.5% real checks correctly at 0% misreading rate.

Abstract: The Abstract Abstract of Thesis Entitled "Segmentation and Recognition of Chinese Bank Cheque Amounts" submitted by LAU Kwok Wai for the degree of Master of Philosophy at The University of Hong Kong in December 2003. Abstract A huge number of bank cheques drawn in Chinese are processed every day in Hong Kong, Mainland China, and elsewhere in Asia. This is an enormous and time-consuming task, which at present is still performed manually. Although much research has been done into automating the recognition of English and numeric amounts on bank cheques, it has so far proved to be very difficult to develop specific methods for recognizing Chinese amounts. The main problem is to correctly separate each character from the image of a character string in which the characters overlap with or touch each other. This study proposes three approaches for the recognition of handwritten Chinese amounts. They are the Extended Tseng's method, the Modified Yu's method and the Segmentation-free method. Each method has its own merits. The Extended Tseng's method merges character components by using knowledge-based merging method which significantly reduces The Abstract recognition errors because most of the merged components are complete characters rather than unknown fragments. The Modified Yu's method improves segmentation performance by accurately decomposing the connected segments whose width exceed pre-defined thresholds. The Segmentation-free method uses a sliding window to capture a sequence of frames from the string image, so that those character segments which have widths less than the preset threshold can also be successfully segmented. Of the three proposed methods, the Extended Tseng's method gives the best performance. With a test set of 192 bank cheques, it scored a recognition rate of 79.8%, a rejection rate of 16.6%, and a substitution error rate of 3.6%. The error rate of 3.6% is lower than that of other existing models, and is considered satisfactory.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the rapid advances in computers and communication technologies, a number of large-scale applications continue to rely heavily on the use of paper as the dominant medium, either in an intra-organizational or an inter-organizational environment. One major example of this category of paper intensive applications is the check processing application. In a number of countries, the value of each check is read by human eyes before the check is physically transported, in stages, from the point it was presented to the location of the branch of the bank which issued the blank check to the concerned account holder. This process of manual reading of each check involves significant time and cost. In this paper, a new approach is proposed to read the numerical amount field on the check; this field is also called the courtesy amount field. In the case of check processing, the segmentation of unconstrained strings into individual digits is a challenging task because one needs to accommodate special cases involving: connected or overlapping digits, broken digits, and digits physically connected to a piece of stroke that belongs to a neighboring digit. The system described in this paper involves three stages: the segmentation of the string into a series of individual characters; the normalization of each isolated character; and the recognition of each character based on a neural network classifier.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been a growing interest in the fields of pattern recognition and machine vision in academia and industries. New theories have been developed with new technology and systems designs in both hardware and software. They are widely applied to our daily life to solve real problems in diverse areas such as science, engineering, agriculture, e-commerce, education, robotics, government, medicine, games and animation, medical imaging analysis and diagnosis, military, and national security. The foundation of this field can be traced back to the late Prof. King-Sun Fu, one of the founding fathers of pattern recognition, who, with visionary insight, founded the International Association for Pattern Recognition in 1978. Almost 30 years later, the world has witnessed this field's rapid growth and development. It is probably true to say that most people are affected by or use applications of pattern recognition in daily life. Today, on the eve of 25th anniversary of the unfortunate and untimely passing of Prof. Fu, we are proud to produce this collection works from world renowned professionals and experts in pattern recognition and machine vision in honor and memory of the late Prof. King-Sun Fu. We hope this book will help further promote not only fundamental principles, systems, and technologies but also the vast range of applications that help in solving problems in daily life.

Available in PDF, EPUB and Kindle. Book excerpt: In the US and many other countries, bank checks are preprinted with the account number and the check number in MICB ink and format; as such, these two numeric fields can be easily read and processed using automated techniques. However, the amount field on a filled -in check is usually read by human eyes, and involves significant time and cost, especially when one considers that about 68 billion checks are processed per annum in the US alone. The system described in this paper uses the scanned image of a bank check to "read" the check. There are four main stages in the system that focus on: the detection of courtesy amount block within the image; the segmentation of string into characters; the recognition of isolated characters; and the post processing process that ensures correct recognition. The detection of courtesy amounts is performed using heuristic rules. These rules are applied after processing the image to translate the set of gray pixels into groups of pixels, which are considered as strings. The segmentation of the courtesy amount is the most difficult part of the process because of the largely unconstrained nature of handwritten amounts on checks. The proposed segmentation has been implemented as a recursive process that interacts with the recognition module. The recognition of the isolated characters is based on an array of neural networks that has been demonstrated to be very accurate and computationally efficient. Finally, the post-processing module is used to minimize the incidence of incorrect readings by verifying that the sequence of numbers, periods, and commas matches the correct syntax for the recognized value of the check. Several of the algorithms included in the system are generalizable and can also be applied to address other applications involving reading of handwritten inputs.
