从图像中读取的文本 [英] Text reading from image
本文介绍了从图像中读取的文本的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想从Image中读取一个文本,因为我编写了以下代码。我使用了MODI和OCR方法。这段代码只读取了具有Times New Roman和Arial Font的文本。但实际上我使用的Monotype Carsiva字体的图像无法被代码识别。如何从图像中读取文字,其中包含Monotype Carsiva字体的文字
代码
使用系统;
使用 System.Collections.Generic;
使用 System.Linq;
使用 System.Text;
使用 System.Threading.Tasks;
使用 System.IO;
使用 MODI;
使用 System.Threading;
命名空间 ImageProcessingConsoleApplication
{
class Program
{
静态 void Main( string [] args)
{
// 设置示例图像路径
字符串 ImagePath = AppDomain.CurrentDomain.BaseDirectory + dev.jpg跨度>;
ReadTextFromImage(ImagePath);
// 设置商店图片内容文本文件路径
< span class =code-sdkkeyword> String StoreTextFilePath = AppDomain.CurrentDomain.BaseDirectory + SampleText.txt 跨度>;
ReadTextFromImage(ImagePath,StoreTextFilePath);
Console.ReadLine();
}
public static void ReadTextFromImage( String ImagePath)
{
try
{
// 从图像中抓取文本
MODI。文档ModiObj = new MODI.Document();
ModiObj.Create(ImagePath);
ModiObj.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true , true );
// 检索从图像中收集的文本
MODI.Image ModiImageObj =(MODI.Image)ModiObj.Images [ 0 ];
System.Console.WriteLine(ModiImageObj.Layout.Text);
ModiObj.Close();
}
catch (例外情况)
{
throw new 例外(ex.Message);
}
} 私有 静态 void ReadTextFromImage( String ImagePath, String StoreTextFilePath)
{
尝试
{
MODI.Document ModiObj = 新 MODI。文献();
ModiObj.Create(ImagePath);
ModiObj.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true , true );
// 检索从图像收集的文本
MODI.Image ModiImageObj =(MODI.Image)ModiObj.Images [ 0 ];
// 将图像内容存储在文本文件中
FileStream CreateFileObj = new FileStream(StoreTextFilePath,FileMode.Create);
// 将图像文本保存在文本文件中
StreamWriter WriteFileObj = new StreamWriter(CreateFileObj);
WriteFileObj.Write(ModiImageObj.Layout.Text);
WriteFileObj.Close();
ModiObj.Close();
}
catch (例外情况)
{
throw new 例外(ex.Message);
}
}
}
}

I want to read a text from Image for that i write following code..I Used MODI and OCR methods.This code is only read the text having "Times New Roman" and "Arial Font". but actually image which i used having "Monotype Carsiva" font which can't be recognized by code.How to read text from Image in which text having "Monotype Carsiva" Font
Code

String ImagePath = AppDomain.CurrentDomain.BaseDirectory + "dev.jpg";
ReadTextFromImage(ImagePath);
// Set Store Image Content text file Path
String StoreTextFilePath = AppDomain.CurrentDomain.BaseDirectory + "SampleText.txt";
ReadTextFromImage(ImagePath, StoreTextFilePath);
