Preserving indentation with Tesseract OCR 4.x

本秂侑毒 提交于 2020-01-22 13:16:04
问题 I'm struggling with Tesseract OCR. I have a blood examination image, it has a table with indentation. Although tesseract recognizes the characters very well, its structure isn't preserved in the final output. For example, look the lines below "Emocromo con formula" (Eng. Translation: blood count with formula) that are indented. I want to preserve that indentation. I read the other related discussions and I found the option preserve_interword_spaces=1 . The result became slightly better but as

图片识别OCR:

梦想的初衷 提交于 2020-01-22 13:04:21
使用Python制作一个简易的OCR图片文字识别工具 :键盘上的PrtScr按键+画图工具+百度AI图片识别(账户,调用接口)+python 常见的OCR工具: 1. Microsoft Onenote 实在是找不到那个右键 --> copy as text 2. Google One Drive 对中文的效果不好,另外境内访问慢 3. lightpdf基础版 缺点在于基础版只可以选择一个语言,对于中英文都有的代码,选择英文时中文会有乱码 4. 城华ocr 每天有免费的quota限制:https://zhcn.109876543210.com/ 5. 优图OCR 直接在页面上进行上传和取结果,识别效果不错! 6. OCRMaker 7 天若OCR文字识别工具 百度云盘:https://pan.baidu.com/s/1c4exWli 提取码:e2pj 使用方法 1、默认快捷键F4,可以自行修改,在托盘图标右键设置里可以修改。 2、截图之后松开左键即可。软件在设计的方面参考了论坛的诸多软件的设计。 来源: https://www.cnblogs.com/jieruishu/p/12228313.html

UiPath-浅谈自带OCR

跟風遠走 提交于 2020-01-21 18:25:18
UiPath-浅谈自带OCR 缘起 常见形式 UiPath+本地引擎 限制 公众号 缘起 OCR ,全名Optical Character Recognition(光学字符识别),实现方法各家不同,从业务层面讲就是识别图片文字。有些朋友可能会感觉这技术是近几年才耳熟起来的,但实际上OCR是二战前就诞生的老家伙了,而且针对中文的OCR也是文革前就有人在搞的。多亏了现代发展的AI buff,这位老大哥的才渐渐崭露头角,这些年宣传的人尽皆知的支付宝扫福就是由机器学习技术支撑的超大型文字识别项目。感慨到此为止,下面简单讲讲OCR在RPA中的表现。 常见形式 国内宣传的最厉害的就是百度、阿里、讯飞、Abbyy这些个巨头,最常见的使用方法,就是利用网络请求把图片的数据传给他们的服务器,然后坐等识别结果。这个在UiPath里使用请求活动就可以在流程中实现 好处是图片识别功能的培训几位霸霸已经做好了,不需要占用太大的本地空间部署,可以不用指定识别目标,而且可以享受到AI buff,真香。 坏处嘛,信息稍微涉密都不要想用这种方法。 使用本地引擎,比如UiPath自身就可以使用微软、谷歌还有Tesseract的引擎;或者本地下载别的OCR产品,UiPath可以使用命令行去指挥。 好处首先就是安全,也不会受网络状况影响。 坏处就是需要相应的语言包,本地占地大一些,环境的配置会比较麻烦。而且,没有AI助攻

Remove borders from image but keep text written on borders (preprocessing before OCR)

蓝咒 提交于 2020-01-21 12:16:50
问题 Having an image such as one above, I am able to crop it into four square boxes, remove the borders using OpenCV morphological operations (basic dilation, erosion) and get a result such as: Which works great in most cases, but if someone writes over the line, this may get predicted as 7 instead of 2. I am having trouble finding a solution that would recover the parts of the character written over the line while removing the borders. Images I have are already converted to grayscale so I can't

Processing an image of a table to get data from it

时光总嘲笑我的痴心妄想 提交于 2020-01-20 13:07:46
问题 I have this image of a table (seen below). And I'm trying to get the data from the table, similar to this form (first row of table image): rows[0] = [x,x, , , , ,x, ,x,x, ,x, ,x, , , , ,x, , , ,x,x,x, ,x, ,x, , , , ] I need the number of x's as well as the number of spaces. There will also be other table images that are similar to this one (all having x's and the same number of columns). So far, I am able to detect all of the x's using an image of an x. And I can somewhat detect the lines. I

How to extract text or numbers from images using python

OCR识别移动端的实现与应用

OCR识别移动端的实现与应用 手动输入太慢?手动输入太烦?手动输入容易出错? 那您需要仔细看看我的文章了。 为了解决这一问题从而诞生了移动端OCR识别的新兴产业,当然了对于无芯片的行驶证也是可以支持的。市面上的Android、iOS两种操作系统的手机同时支持自动识别录入车牌号信息。 那这一功能具体怎么操作实现的呢? 首先在手机APP集成OCR识别SDK开发包通过正确的操作方式来扫描需识别的信息证件车牌在APP上输出显示的信息来实现。 移动端OCR识别技术简单来说是指通过计算机视觉、图像处理与模式识别等方法从车辆图像中提取车牌字符信息,从而确定车辆身份的技术。 在我们的日常生活中您认真观察就可以发现这一技术已经应用在我们生活当中的很多地方了。 早上开车上高速,ETC自助通道,无人值守,车牌自动识别; 到公司停车场,无需停车取卡,车牌自动识别进入; 下班开车回家,车牌识别自动结算停车费用。 除此之外,扫一扫车牌,车辆检测、维修、保养、续保等,登录厂家APP,自动录入车牌信息,无需手工操作,无需等待。更好的解决目前交通中的一些问题。 当然目前市面上的车牌中来也是很多包括蓝牌、黄牌、挂车号牌、新军牌、警牌、新武警车牌、教练车牌、大使馆车牌、农用车牌、个性化车牌、港澳出入境车牌、澳台车牌、民航车牌、领馆车牌、新能源车牌等。 这些都能识别吗?
