Bit plane decomposition and the scanning n-tuple classifier
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 207-211
S. Hoque, K. Sirlantzis, M.C. Fairhurst
This paper describes a multiple classifier configuration for high performance off-line handwritten character recognition applications. Along with a conventional scanning n-tuple classifier (or sn-tuple) implementation, three other sn-tuple systems have been used which are trained using a binary feature set extracted from the contour chain-codes using a novel decomposition technique. The overall ac... hiện toàn bộ

Treadmill ink - enabling continuous pen input on small devices
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 215-220
G. Seni
This paper presents a novel handwriting input user interface (UI)for small portable devices with a touch-enabled screen. This UI includes a writing area on the screen that behaves as a "treadmill" such that electronic ink input is immediately moved from right to left while it is being entered, giving the user the feeling of writing text on a virtual "ticker-tape". This method allows the user to wr... hiện toàn bộ

Slant correction of handwritten strings based on structural properties of Korean characters
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 467-472
Daekeun You, Gyeonghwan Kim
A slant correction method for handwritten Korean strings based on analysis of stroke distribution, which reflects structural properties of Korean characters, is presented in this paper. The method aims to deal with typical problems which have been frequently observed in slant correction of handwritten Korean strings with conventional approaches developed for English/European languages. Extracted s... hiện toàn bộ

Separating text and background in degraded document images - a comparison of global thresholding techniques for multi-stage thresholding
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 244-249
G. Leedham, S. Varma, A. Patankar, V. Govindaraju
Before any processing of the textual content of a document image can be performed the text must be separated from the background of the image. Several thresholding algorithms have previously been proposed and are widely used in document processing. None have been shown effective at thresholding difficult documents where the background and foreground are non-uniform. In this paper we investigate th... hiện toàn bộ

Integrated segmentation and recognition of handwritten numerals: comparison of classification algorithms
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 303-308
Cheng-Lin Liu, H. Sako, H. Fujisawa
In integrated segmentation and recognition (ISR) of handwritten character strings, the underlying classifier is desired to be accurate in character classification and resistant to non-character patterns (also called garbage or outliers). This paper compares the performance of a number of statistical and neural classifiers in ISR. Each classifier has some variations depending on learning method: ma... hiện toàn bộ

Linguistic integration information in the AABATAS Arabic text analysis system
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 389-394
S. Kanoun, A. Ennaji, Y. Lecourtier, A.M. Alimi
An Arabic text analysis system called AABATAS (affixal approach-based Arabic text analysis system) is proposed. AABATAS recognizes and categorizes the words while identifying their morphological and grammatical characteristics. It is based on a new approach for Arabic word recognition called affixal approach. This affixal approach is guided by the structural properties of language. A dynamic decom... hiện toàn bộ

Genetic engineering of handwriting representations
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 145-150
A. Lemieux, C. Gagne, M. Parizeau
This paper presents experiments with genetically engineered feature sets for recognition of online handwritten characters. These representations stem from a nondescript decomposition of the character frame into a set of rectangular regions, possibly overlapping each represented by a vector of 7 fuzzy variables. Efficient new feature sets are automatically discovered using genetic programming techn... hiện toàn bộ

On-line handwriting recognition using character bigram match vectors
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 67-71
A. El-Nasan, M. Perrone
Describes an adaptive, partial-word-level, writer,dependent, handwriting recognition system that utilizes the character n-gram statistics of the English language. The system exploits the linguistic property that very few pairs of English words share exactly the same set of character bigrams. This property is used to bring linguistic context to the recognition stage. The recognition is based on, es... hiện toàn bộ

A handwritten character recognition method based on unconstrained elastic matching and eigen-deformations
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 72-77
S. Uchida, H. Sakoe
A fast elastic matching based handwritten character recognition method is investigated. In the method, an unconstrained elastic matching technique, where the matching is optimized locally and individually on each pixel, is utilized together with its a posteriori evaluation based on the eigen-deformations of handwritten characters. Our experimental results show that high recognition rates can be at... hiện toàn bộ

Writer identification by writer's invariants
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition - - Trang 274-279
A. Bensefia, A. Nosary, T. Paquet, L. Heutte
This communication deals with the problem of writer identification. If the assumption of writing individuality is true then graphical fragments that constitute it should be individual too. Therefore we propose a morphological grapheme based analysis to make writer identification. Template Matching is the core of the approach. The redundancy of the individual patterns in a writing, defined as the w... hiện toàn bộ
