‘壹’ 用JAVA编写一个程序识别图片上的文字;这个难题你实现了吗
这种不是个人可以处理的,也不是java的强项,去找提供ocr api的厂商吧。
‘贰’ 谁能给个Java写的ocr文字识别的demo
JAVA实现网络OCR文字识别功能
http://blog.csdn.net/javagirlone/article/details/47807963
‘叁’ 如何用Java及OCR开发批量图片内容转文字
可以到云脉OCR SDK开发者平台下载文档识别API接口文档啊,开发支持Java、C++、C、 object pascal及objective-C等多种语言!可以用接入的OCR识别功能轻松实现批量图片内容转文字的操作
‘肆’ java 如何读取附加到图片上的文字
图片上的文字是没法读取的,以为这涉及到图像处理。非常非常复杂!因为如果你非要读取图片上的文字,不是几行代码可以搞定的,首相从matlaB开始学,了解什么是图像处理。然后再开发相应的jar包。当然,你也可以使用相关的软件工具,比如识图软件,通过读取软件的反馈也算是读取了图片上的文字
‘伍’ 用Java读取一张图片,并识别图中的所有汉字,怎么解决
这个要是自己去写,估计很难,需要用到很多AI智能的算法,可以调用谷歌或者网络的识图API
‘陆’ 一张图片 里面既有图像也有文字,但是我就想要文字,不要图片,用java 实现,怎么办!
很难实现。如果你这都能实现,那就是高手高手高高手了。
‘柒’ java截图后怎么用tesseract 文字识别
网上传的代码示例大多是在Windows下安装Tesseract ORC后通过CMD命令操作进行图识别操作.而 Tess4j 针对Tesseract 提供了JNI支持,同时还提供了一些图片操作的工具类,提供比如图片放大,旋转,黑白处理,锐化 等用来提高识别率的操作.操作十分方便. T
‘捌’ 怎么用java实现图片里面的数字识别
图片是由点组成(或者是别的方法),记录点的位置、颜色,控制点就行了。至于ocr,有难度,首先要制作文字的变化范围及整个字各部分的联系,这还是简单的。然后,图像分解就行了。额,我不会编程,稍微会点c++,所以这个回答就是假设如果我做这种程序的思路。
‘玖’ java 实现图片的文字识别
摘要图像识别是目前很热门的研究领域,涉及的知识很广,包括信息论、模式识别、模糊数学、图像编码、内容分类等等。本文仅对使用Java实现了一个简单的图像文本二值处理,关于识别并未实现。
步骤
建立文本字符模板二值矩阵
对测试字符进行二值矩阵化处理

‘拾’ java有读取图片里面文字的方法吗
使用tesseract-ocr,可以识别简单的验证码,中文没尝试过
