ocr'ing application text (not scanned, NOT captchas)

由 萝らか妹 提交于 2020-01-13 19:37:28
问题 I'd like to interface an application by reading the text it displays. I've had success in some applications when windows isn't doing any font smoothing by typing in a phrase manually, rendering it in all windows fonts, and finding a match - from there I can map each letter image to a letter by generating all letters in the font. This won't work if any font smoothing is being done, though, either by Windows or by the application. What's the state of the art like in OCRing computer-generated

How to remove OCR artifacts from text?

由 ⅰ亾dé卋堺 提交于 2020-01-13 11:29:10
问题 OCR generated texts sometimes come with artifacts, such as this one: Diese grundsätzliche V e r b o r g e n h e i t Gottes, die sich n u r dem N a c h f o l g e r ö f f n e t , ist m i t d e m Messiasgeheimnis gemeint While it is not unusual, that the spacing between letters is used as emphasis (probably due to early printing press limitations), it is unfavorable for retrieval tasks. How can one turn the above text into a more, say, canonical form, like: Diese grundsätzliche Verborgenheit

Tesseract False Space Recognition

由 萝らか妹 提交于 2020-01-13 09:06:12
问题 I'm using tesseract to recognize a serial number. This works acceptable, common problem like false recognition of zero and "O", 6 and 5, or M and H exists. Beside by this tesseract adds spaces to the recognized words, where no space is in the image. The following image is recognized as "HI 3H" . This image results in " FBKHJ 1R1" So tesseract added a space, although there isn't really a space in the image. Is there a possibility parametrize the spacing behavior of tesseract? Edit I'm sorry,

编辑：David Doermann(马里兰大学) Karl Tombre(洛林大学) 前言 In the beginning, there was only OCR. After some false starts, OCR became a competitive commercial enterprise in the 1950’s. A decade later there were more than 50 manufacturers in the US alone. With the advent of microprocessors and inexpensive optical scanners, the price of OCR dropped from tens and hundreds of thousands of dollars to that of a bottle of wine. Software displaced the racks of electronics. By 1985 anybody could program and test their ideas on a PC, and then write a paper about it (and perhaps even patent it). 最初，只有OCR。在经历了一些错误的开始之后

How does one install Tesseract-OCR 3.03 in Ubuntu/Linux distributions?

由 邮差的信 提交于 2020-01-12 13:44:21
问题 A friend and I are interested in training the tesseract-OCR engine for a CV project. We tried using some wrappers such as PyTesser and pyocr, but the results are currently not as accurate as we need them to be. As such, we want to try training the tesseract to perform better for our purposes (i.e. identifying text on food labels), but are having some trouble installing the training tools. What we've tried: Looking on the google code website, the 'Compiling' page on the tesseract's google code

Setting environment variable TESSDATA_PREFIX in Tomcat

由 扶醉桌前 提交于 2020-01-12 10:42:32
问题 We are using Tesseract OCR Java library called Tess4J. It works fine if run as a standalone application. It needs a variable called TESSDATA_PREFIX which contains the tessdata config and other charset related files. It also runs fine with embedded Tomcat 6 server in eclipse. I had set TESSDATA_PREFIX as an environment variable by using the launch configuration. But when I package everything into a WAR and drop it in deploy directory of tomcat, the environment variable does not seem to be
