help with OCR application - Matlab

由 我与影子孤独终老i 提交于 2019-12-12 18:04:36
问题 I'm really need your help, I'm desperate. I'm trying to build an OCR application and I'm facing some problems that I can't solve alone. for now I'm cutting the plate form the image and doing some filtering to reduce the noise. for example, this is the plate after cutting it from the image and after filtering: now because that the plate is in angle and because that there is still noise (like above the numbers 9 and 3), the identification process(using corr2) is giving me the wrong numbers. eg:

Tesseract has trouble reading this extremely simple string of numbers

由 偶尔善良 提交于 2019-12-12 12:33:11
问题 I'm currently writing a script in python that requires the use of tesseract to read a number like this: Using digits only and -psm 6 (or 7) it outputs 5.551 I have had some success with other numbers (5.700 works) but this particular number is giving me a ton of problems. Unfortunately i need a high degree of accuracy for my program but i thought tesseract would be able to decipher such a simple string. I have also tried to use GOCR and that correctly read 6.881 (yay!) but gave the output 5.

Does Matlab have builtin OCR library or toolkit?

由 吃可爱长大的小学妹 提交于 2019-12-12 12:06:06
问题 I need a pre-built (i.e. already trained) OCR library that recognizes easy characters (standard fonts like Arial, Times New Roman, Courier, etc). Does Matlab have anything like that in one of its toolboxes? Or do I have to use an external program like Tesseract (and interface using system calls)? 回答1: I'm not familiar with an official MATLAB OCR toolbox. However, you can find all sorts of gems in the MATLAB File Exchange, like this OCR tool. It's pretty neat. 回答2: In MATLAB R2014a there's a

驾驶证、行驶证识别 一、OCR证件识别技术种类 OCR识别技术可谓当下人工智能领域最为火热的一项技术，在各种APP爆发式增长的同时，可以看到的是几乎所有的智能软件，开发人员如果想要提高客户人机交互的感受，那么智能识别技术是一个必选项。那么总体来说当今的ocr识别技术主要细分为以下功能：ocr综合文字识别、ocr视频文字识别、人脸识别、证件识别、票据识别、车牌Vin码识别、银行卡识别、云识别。那么今天就和大家聊聊应用广泛的证件识别。 二、OCR识别技术应用背景 这些年，随着移动互联网的的发展，越来越多的企业都推出了自己的移动APP，这些APP多数都涉及到个人身份证信息的输入认证（即实名认证），如果手动去输入身份证号码和姓名，速度非常慢，且用户体验非常差。为了提高在移动终端上输入身份证信息的速度和准确性，OCR证件识别技术应运而生。需要说明的是OCR证件识别不仅仅只有身份证识别，还有护照识别以及其他，但是我们今天就应用最广泛的身份证进行说明。 三、OCR手机身份证号识别技术简介 OCR手机身份证号识别技术SDK可支持Android、iOS主流移动操作系统，android平台提供jar包，ios提供静态库.a文件。APP集成OCR手机身份证号识别技术SDK后，用户采用手机、平板电脑对身份证进行拍摄识别即可自动识别身份证信息(如图-1所示)；

Do any Java OCR tools convert images of text into editable text files?

由 倖福魔咒の 提交于 2019-12-12 08:58:48
问题 I'm working on a project that entails photographing text (from any hard copy of text) and converting that text into a text file. Then I'd like to use that text file to do some different things, such as provide hyperlinks to news articles or allow the user to edit the document. The tool I've tried so far is Java OCR from sourceforge.net, which works fine on the images provided in the package. But when I photograph my own text, it doesnt work at all. Is there some training process I should be

What software would you recommend for image enhancement prior to OCR (Optical Character Recognition)? [closed]

由 无人久伴 提交于 2019-12-12 08:13:57
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . We are currently researching ways of enhancing image quality prior to submission to OCR. The OCR engine we are currently utilizing is the Scansoft API from Nuance (v15). We were researching the Lead Tools but have since decided to look elsewhere. The licensing costs associated with Lead Tools is just too great.

How to get the directory that needs to be used in tessbase.init(“directory”, “eng”)?

I can't figure out how to get the directory that contains tessdata. This is an image of the directory that contains eng.traineddata. This is my code: Bundle extras = data.getExtras(); Bitmap photoBitmap = (Bitmap) extras.get("data"); TessBaseAPI baseApi = new TessBaseAPI(); //textcaptured.setText(DATA_PATH.toString());/* String dataPath
