Nghiên cứu về việc sử dụng CDHMM cho nhận dạng chữ Hán viết tay với từ vựng lớn Dịch bởi AI
- Trang 334-338
Chúng tôi (2002) đã nghiên cứu cách sử dụng mô hình Markov ẩn liên tục với hỗn hợp Gaussian (CDHMM) để mô hình hóa và nhận diện chữ Hán viết tay. Chúng tôi đã xác định và phát triển một tập hợp các kỹ thuật có thể được sử dụng để xây dựng một hệ thống nhận diện ngoài dây dựa trên CDHMM thực tiễn cho một từ vựng lớn của các ký tự chữ Hán viết tay. Chúng tôi đã báo cáo ở nơi khác về các kỹ thuật chí......

Hidden loop recovery for handwriting recognition
- Trang 375-380
One significant challenge in the recognition of off-line handwriting is in the interpretation of loop structures. Although this information is readily available in online representation, close proximity of strokes often merges their centers making them difficult to identify. In this paper a novel approach to the recovery of hidden loops in off-line scanned document images is presented. The propose......

A new database for research on bank-check processing
- Trang 524-528
This paper presents a new database for off-line handwriting recognition. The database, that is particularly devoted to research on bank-check recognition, up to now includes instances of isolated digits and characters, basic words of worded amounts, and signatures. Pattern images are stored using a standard image format, and hence they are easily usable by several commercial and scientific image p......

An algorithm for online strokes verification of Chinese characters using discrete features
- Trang 339-344
Existing Chinese educational software tools teach the students at the primary or kindergarten levels the stroke movements and stroke order of each Chinese character by animating the individual strokes of the whole character, one stroke at a time. In this paper the author presents an algorithm which allows the student to hand-write a specified character online through the computer, and which checks......

Classifying isogenous fields
- Trang 41-46
Classifiers that utilize style context in co-occurring patterns increase recognition accuracy. When patterns occur as long isogenous fields, this gain should increase unless negated by parameter estimation errors that increase with field length. We show that our method achieves higher accuracy with longer input fields because it can be trained accurately We also present some ongoing work on simple......

Online handwriting recognition with support vector machines - a kernel approach
- Trang 49-54
In this paper we describe a novel classification approach for online handwriting recognition. The technique combines dynamic time warping (DTW) and support vector machines (SVMs) by establishing a new SVM kernel. We call this kernel Gaussian DTW (GDTW) kernel. This kernel approach has a main advantage over common HMM techniques. It does not assume a model for the generative class conditional densi......

Hybrid adaptation: integration of adaptive classification with adaptive context processing
- Trang 169-174
We propose a new method of adaptation in online handwritten character recognition. The method, called the "hybrid adaptation", integrates adaptive classification with adaptive context processing. Hybrid adaptation includes a mechanism that minimizes the negative effects of adaptation that might be caused by the integration. Online handwritten character recognition software with hybrid adaptation c......

Baseline estimation for Arabic handwritten words
- Trang 479-484
Baseline information has been used for diverse purposes in handwriting research. The baseline represents a first orientation in a word and it is often a precondition for subsequent algorithms, including preprocessing tasks, segmentation and feature extraction for recognition systems. Approaches based on the horizontal projection histogram are used for Arabic printed text but they are ill-suited fo......

Recognition of courtesy amounts on bank checks based on a segmentation approach
- Trang 298-302
A segmentation based courtesy amount recognition (CAR) system is presented in this paper. A two-stage segmentation module has been proposed, namely the global segmentation stage and the local segmentation stage. At the global segmentation stage, a courtesy amount is coarsely segmented into sub-images according to the spatial relationships of the connected components. These sub-images are then veri......
