本標(biāo)準(zhǔn)規(guī)定了印刷圖象的形狀和尺寸,它既符合人們閱讀的習(xí)慣,又適用于機(jī)器的讀出,以便易于和促進(jìn)光學(xué)字符識(shí)別(OCR)在數(shù)據(jù)處理中的應(yīng)用。 本標(biāo)準(zhǔn)規(guī)定了用于光學(xué)字符識(shí)別的字母數(shù)字字符、圖形和符號(hào)的印刷圖象的形狀和尺寸,也適用于一般的用途。 所設(shè)計(jì)的OCR-B的字符形狀,既適用于OCR系統(tǒng),且在更廣泛的應(yīng)用范圍內(nèi)也適用于一般的用途,而不至于造成過分的不方便。OCR-B的字符大小用三種尺寸給出。
本標(biāo)準(zhǔn)定義了制造業(yè)信息化領(lǐng)域所用的有關(guān)技術(shù)術(shù)語,包括信息技術(shù)基礎(chǔ)理論部分的基本術(shù)語和信息技術(shù)在制造業(yè)中應(yīng)用部分的技術(shù)術(shù)語,以及國內(nèi)技術(shù)市場上出現(xiàn)的新的詞匯。本標(biāo)準(zhǔn)適用于與制造業(yè)信息化技術(shù)有關(guān)的科研、生產(chǎn)、工程、管理、經(jīng)營、教育等部門。本標(biāo)準(zhǔn)技術(shù)內(nèi)容支持現(xiàn)代設(shè)計(jì)工程和企業(yè)信息化所要求的設(shè)計(jì)、制造、管理、集成、通信互連、網(wǎng)絡(luò)及相關(guān)信息技術(shù)等方面的術(shù)語。
GB/T 20225的本部分旨在方便電子文件管理領(lǐng)域內(nèi)的交流和術(shù)語的翻譯。本部分通篇所用的“電子文檔管理”是作為輸入技術(shù)(掃描、索引、光學(xué)字符識(shí)別、格式、數(shù)字生成等)、管理技術(shù)(文檔服務(wù)、工作流及其他工作管理工具)以及存儲(chǔ)(主要是光學(xué)存儲(chǔ)或磁存儲(chǔ))技術(shù)的通用術(shù)語。
本標(biāo)準(zhǔn)規(guī)定了光學(xué)字符閱讀紙的產(chǎn)品分類、技術(shù)要求、試驗(yàn)方法、檢驗(yàn)規(guī)則和標(biāo)志、包裝、運(yùn)輸、貯存。本標(biāo)準(zhǔn)適用于光電錄入技術(shù)所用的光學(xué)字符閱讀紙。
本標(biāo)準(zhǔn)規(guī)定了印刷文獻(xiàn)的原件制作指導(dǎo),以便更易被縮微復(fù)制或影像掃描復(fù)制。雖然本標(biāo)準(zhǔn)更多是針對具體的拉丁字母,但是其一般原則也適用于使用其他字母或意符的文獻(xiàn)制作。本標(biāo)準(zhǔn)不適用于GB/T 14689和GB/T 10609.4中給出的技術(shù)制圖的條件。同樣也不適用于特殊的縮微影像技術(shù)或相關(guān)的掃描使用(銀行支票或條碼掃描)。
本標(biāo)準(zhǔn)規(guī)定了收集、篩選、保存和維護(hù)核電廠退役需要的文件和記錄的方法及一般要求。本標(biāo)準(zhǔn)主要適用于核電廠業(yè)主和(或)營運(yùn)單位對核電廠退役需要的文件和記錄的管理,其他核設(shè)施退役可參照執(zhí)行。
This European Standard specifies optical characteristics for processing letters and gives guidelines on the valuesof these attributes that will assure a high level of address readability. It is aimed at facilitating relations betweenPostal Operators and Customers by providing information that mailers can use to ensure that the addresses theyprint can be processed successfully by postal automation systems.The standard is intended to support:??assessment of the probable readability of a printed address, using given address recognition equipment,without actually submitting it to the equipment;??determination of the changes in address printing characteristics that are required to achieve a desired level ofaddress readability using given address recognition equipment;??assessment of the complexity, and thus the cost, of the address recognition equipment needed to achieve adesired level of readability of addresses with given printing characteristics.The standard applies to mail items whose size is up to and including C51, but may also be applied to oversizeitems, commonly referred to as C5+, and to flats. The address blocks covered are:??the delivery address block;??the sender address block if this is printed on the same side of the mail item as the delivery address block.The guidelines provided in the standard apply to address blocks as they appear on finished mail items whensubmitted to postal operators, and not just to addresses and the substrate on which they are printed. Users of thestandard are responsible for determining the physical parameters which are required to achieve compliance aftertaking account of characteristics which result from mail item features, other than printing, such as covering, the useof transparent window envelopes and the use of address labels.The guidelines are based on physical attributes that tend to influence the readability of addresses by opticalcharacter recognition (OCR) equipment and by video-coders. To the extent that this is possible, attributes havebeen selected so as to be easily controllable and to be measurable using simple, low-cost, means. The attributevalues given are based on common notions of typography and on colour reference systems that are likely to beknown by mailers. The values given should be interpreted as recommendations or guidelines, not as strict,mandatory, all-or-nothing rules.OCR systems are complex and their behaviour is therefore not easily modelled by simple attributes. As a result theambition of the standard is limited by the difficulty of defining some attributes in formal terms, even though theirinfluence on address readability has been proven. Where this is the case, the standard uses examples, lists ofpreferred values, or literal descriptions to give hints on how to maximise address readability.Since all attributes do not contribute uniformly to the readability of an address, the standard identifies two levels ofsalience for each attribute (high and normal). These two levels are designed to aid in the definition of readabilityclasses by users of the standard.This standard considers a printed address as being made up of a series of lines of printed information2. Guidelinesrelated to such address lines are relevant for all lines in an address block.
