OCR Indonesia dalam C#dan .NET

Versi lain dari dokumen ini:

IronOCR adalah komponen perangkat lunak C# yang memungkinkan pembuat kode .NET membaca teks dari gambar dan dokumen PDF dalam 126 bahasa, termasuk bahasa Indonesia.

Ini adalah cabang lanjutan dari Tesseract, dibuat secara eksklusif untuk para pengembang .NET dan secara teratur mengungguli mesin Tesseract lainnya dalam hal kecepatan dan akurasi.

Isi IronOcr.Languages.Indonesian

Paket ini berisi 55 bahasa OCR untuk .NET:

  • Bahasa Indonesia
  • IndonesianBest
  • IndonesianFast

Unduh

Paket Bahasa Indonesia [Bahasa Indonesia]

Instalasi

Hal pertama yang harus kita lakukan adalah menginstal paket OCR Indonesia kita ke proyek .NET Anda.

Install-Package IronOCR.Languages.Indonesian

Contoh Kode

Contoh kode C# ini membaca teks bahasa Indonesia dari dokumen Gambar atau PDF.

// Ensure the IronOcr library is installed
using IronOcr;

// Create a new instance of IronTesseract
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Indonesian; // Set the language to Indonesian

// Use 'using' keyword to ensure resources are cleaned up
using (var Input = new OcrInput(@"images\Indonesian.png"))
{
    // Perform OCR on the input image
    var Result = Ocr.Read(Input);
    // Store the result text
    var AllText = Result.Text;
}
// Ensure the IronOcr library is installed
using IronOcr;

// Create a new instance of IronTesseract

Mengapa Memilih IronOCR?

IronOCR adalah pustaka perangkat lunak .NET yang mudah dipasang, lengkap, dan terdokumentasi dengan baik.

Pilih IronOCR untuk mencapai akurasi 99,8% + OCR tanpa menggunakan layanan web eksternal, biaya berkelanjutan, atau mengirim dokumen rahasia melalui internet.

Mengapa pengembang C# memilih IronOCR daripada Vanilla Tesseract:

  • Pasang sebagai DLL atau NuGet tunggal
  • Termasuk untuk Tesseract 5, 4 dan 3 Engine di luar kotak.
  • Akurasi 99,8% secara signifikan mengungguli Tesseract biasa.
  • Kecepatan Tinggi dan MultiThreading
  • MVC, WebApp, Desktop, Konsol & Aplikasi Server kompatibel
  • Tidak ada kode Exes atau C ++ untuk digunakan
  • Dukungan PDF OCR penuh
  • Untuk melakukan OCR hampir semua file Gambar atau PDF
  • Dukungan penuh .NET Core, Standard dan FrameWork
  • Terapkan di Windows, Mac, Linux, Azure, Docker, Lambda, AWS
  • Baca kode batang dan kode QR
  • Ekspor OCR sebagai XHTML
  • Ekspor OCR ke dokumen PDF yang dapat dicari
  • Dukungan multithreading
  • 126 bahasa internasional semuanya dikelola melalui file NuGet atau OcrData
  • Ekstrak Gambar, Koordinat, Statistik, dan Font. Bukan hanya teks.
  • Dapat digunakan untuk mendistribusikan ulang Tesseract OCR di dalam aplikasi komersial & eksklusif.

IronOCR bersinar saat bekerja dengan gambar dunia nyata dan dokumen yang tidak sempurna seperti foto, atau pindaian resolusi rendah yang mungkin memiliki gangguan atau ketidaksempurnaan digital.

Pustaka OCR gratis lainnya untuk platform .NET seperti API .net tesseract dan layanan web lainnya tidak bekerja dengan baik pada kasus penggunaan dunia nyata ini.

OCR dengan Tesseract 5 - Mulai Coding di C#

Contoh kode di bawah ini menunjukkan betapa mudahnya membaca teks dari gambar menggunakan C# atau VB .NET.

OneLiner

// Perform a quick OCR on the screenshot and output the text
string Text = new IronTesseract().Read(@"img\Screenshot.png").Text;
// Perform a quick OCR on the screenshot and output the text
string Text = new IronTesseract().Read(@"img\Screenshot.png").Text;
' Perform a quick OCR on the screenshot and output the text

OCR pada Area Gambar Tertentu

Semua metode pemindaian dan pembacaan IronOCR menyediakan kemampuan untuk menentukan dengan tepat bagian mana dari suatu halaman atau halaman yang teksnya ingin kita baca. Ini sangat berguna saat kita melihat formulir standar dan dapat menghemat banyak waktu serta meningkatkan efisiensi.

Untuk menggunakan crop region, kita perlu menambahkan referensi sistem ke System.Drawing sehingga kita bisa menggunakan objek System.Drawing.Rectangle.

using IronOcr;
using System.Drawing;

// Create a new instance of IronTesseract
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Indonesian; // Set the language to Indonesian

using (var Input = new OcrInput())
{
    var ContentArea = new System.Drawing.Rectangle() { X = 215, Y = 1250, Height = 280, Width = 1335 };
    // Dimensions specified in pixels

    Input.Add("document.png", ContentArea); // Add cropped area of the image

    var Result = Ocr.Read(Input); // Perform OCR
    Console.WriteLine(Result.Text); // Output the result text
}
using IronOcr;
using System.Drawing;

// Create a new instance of IronTesseract
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Indonesian; // Set the language to Indonesian

Daftar Filter Gambar OCR

Filter input untuk meningkatkan kinerja OCR yang dibangun di IronOCR meliputi:

  • OcrInput.Rotate (double degrees) - Rotate image clockwise by specific degrees. Use negative numbers for counterclockwise.
  • OcrInput.Binarize () - Converts each pixel to black or white. Useful for very low contrast text-background cases.
  • OcrInput.ToGrayScale () - Converts pixels to grayscale. May not improve accuracy but might speed up processing.
  • OcrInput.Contrast () - Automatically increases contrast, often improving speed and accuracy for low-contrast scans.
  • OcrInput.DeNoise () - Removes digital noise. Only use when noise is suspected.
  • OcrInput.Invert () - Inverts all colors, e.g., white becomes black and vice versa.
  • OcrInput.Dilate () - Morphological operation that adds pixels to the boundaries of objects.
  • OcrInput.Erode () - Morphological operation that removes pixels on object boundaries.
  • OcrInput.Deskew () - Rotates image to correct orientation, improves OCR by compensating for tilted scans.
  • OcrInput.DeepCleanBackgroundNoise () - Heavy noise removal. Use only when extreme background noise is present. High CPU cost.
  • OcrInput.EnhanceResolution - Improves low-resolution images, automatically activated based on DPI settings.

CleanBackgroundNoise. Allows automatic cleaning of digital noise, creased paper, and other imperfections that hamper OCR.

EnhanceContrast boosts text contrast against backgrounds, improving OCR accuracy and performance.

EnhanceResolution detects low-resolution images and enhances them for optimal OCR readability, despite increased processing time.

Bahasa While IronOCR supports multiple languages, it provides specific settings to apply multiple languages for OCR operations.

Strategi Two OCR strategies: fast, less accurate versus a detailed AI-driven approach for higher text accuracy.

ColorSpace Choose grayscale or color OCR. Grayscale is preferred, but full color may improve results for similar shade texts.

DetectWhiteTextOnDarkBackgrounds. Automatically detects negative/white text on dark backgrounds, ensuring accurate reads.

InputImageType Guides OCR library for full document or snippet (e.g., screenshot) processing.

RotateAndStraighten Corrects documents with rotation and perspective issues, especially useful for photographed text.

ReadBarcodes Automatically reads barcodes and QR codes during text processing with minimal performance impact.

ColorDepth. Higher color depth may improve OCR quality but can extend processing time.

126 Paket Bahasa

IronOCR mendukung 126 bahasa internasional melalui paket bahasa yang didistribusikan sebagai DLL, yang dapat diunduh dari situs web ini , atau juga dari NuGet Package Manager .

Bahasa termasuk Jerman, Prancis, Inggris, Cina, Jepang, dan banyak lagi. Paket bahasa spesialis tersedia untuk paspor MRZ, cek MICR, Data Keuangan, Plat nomor dan banyak lagi. Anda juga dapat menggunakan file ".traineddata" tesseract - termasuk yang Anda buat sendiri.
