摘要:

目前的工作目标是开发一个光学字符识别(OCR)引擎的信息即时(iJIT)系统,可用于识别的手写文本注释小写罗马脚本。Apache License 2.0下的Tesseract开源OCR引擎用于开发用户特定的手写识别模型,即,对于所述系统,所述语言设置,其中每个用户由与数字笔相关联的唯一标识标签来标识。为了为任何用户生成语言集,Tesseract都是用标记的手写数据样本进行训练的,这些样本是从该用户那里专门收集的孤立和自由流动的罗马字母文本。设计的系统在五种不同的语言集上进行了测试,自由流动的手写注释作为测试样本。该系统对5个不同用户的测试样本分别有87.92%、81.53%、92.88%、86.75%和90.80%的识别率。

英文摘要:

Objective of the current work is to develop an Optical Character Recognition (OCR) engine for information Just In Time (iJIT) system that can be used for recognition of handwritten textual annotations of lower case Roman script. Tesseract open source OCR engine under Apache License 2.0 is used to develop user-specific handwriting recognition models, viz., the language sets, for the said system, where each user is identified by a unique identification tag associated with the digital pen. To generate the language set for any user, Tesseract is trained with labeled handwritten data samples of isolated and free-flow texts of Roman script, collected exclusively from that user. The designed system is tested on five different language sets with free- flow handwritten annotations as test samples. The system could successfully segment and subsequently recognize 87.92%, 81.53%, 92.88%, 86.75% and 90.80% handwritten characters in the test samples of five different users.
