字符识别

There are two ways to achieve, which will be compared in this paper to have a conclusion: basic nerve net theory of number recognition; and optimized basic theory with modify factor.

本文用了两种方法，第一种为基础的神经网络字符识别算法，第二种为基础方法加入动量因子后对网络进行了优化。

This project is to build number plate recognition based on Support Vector Machine technology.

摘要本毕业设计论文的目的是利用支持向量机技术实现汽车牌照的字符识别。

On the basis of the deep research of the OCR techniques, we accomplished the research project successfully.

我们在对字符识别技术进行深入研究的基础上，采取了多种技术措施完成了研究任务。

Now a day, we have created over 70% market share in handwriting market and over 70% in OCR market.

现在， 我们在国内的手写市场占有率超过70%，在光学字符识别的占有率超过50%。

In the new algorithm named BTVCH, the regularizer only consider the direction of four main component of Chinese Character images, so the BTVCH algorithm can enhance the re...

该方法由于充分地考虑了汉字文本图像的结构特征，因此能够很好地保持汉字的笔画的尖锐边缘。实验也证明了使用本文所提出的BTVCH算法获得的超分辨率文本图像可以获得最高的字符识别率。

The right ratio of thetechnique is nearly 100% and the orientation precision of the reticle under a second.

系统字符识别的正确率几乎100%，刻线定位精度达1以上。

Third,based on the model we have presented,word extraction method is discussed and theanalysis of its experiment result is made.

基于所建立的概率模型给出了字符识别系统中词的提取算法并对其进行了实验模拟并对模拟结果进行了分析和讨论。

One of the keys to implement the adaptive character recognition system is to extract right features adaptively.

自动选择合适的特征和特征提取方法是实现自适应字符识别系统的关键之一。

A sort of image acquisition system of paper's number with CIS based on ARM and CPLD is introduced.A re-al-time approach is brought out to collecting high-speed image information and image pretreatment.This system is mainly designed of hardware,the collected CIS image signal is saved in the SDRAM(synchronous dynamic random access memory) through pretreatment of occulting output com-pensation,secondary filter,analog digital converter and binaryzation,getting ready for further image...

介绍了一种自行设计的基于 ARM 及 CPLD 技术，利用接触式图像传感器采集纸币号码的图像采集系统，提出了一种实时采集高速图像信息及图像预处理的方法；系统以硬件设计为主，采集到的 CIS 图像信号经过明暗输出补偿、二阶滤波、模数转换、二值化等前置调理，保存在同步动态内存中，供 ARM 作进一步图像处理；系统中 CIS 传感器的时序信号由 CPLD 设计，实验表明，采集到的二值化图像清晰；这项研究成果可以推广到证券、票据号码的录入系统以及其他相关领域的字符识别系统。

The textual content that is extracted via OCR is put behind the image so search indexers can see it and Acrobat Reader will let us select it as text.

该文本的内容，通过光学字符识别提取的图像置于脑后，使搜索索引可以看到它和Acrobat Reader将让我们选择它作为文本。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
