Aspose.OCR で画像でテキストを検索して比較する方法

using Aspose.OCR;

string img1 = "document1.png";
string img2 = "document2.jpg";

RecognitionSettings settings = new RecognitionSettings();
settings.Language = Language.English; // Adjust as needed

AsposeOcr ocr = new AsposeOcr();
bool isFound = ocr.ImageHasText(img1, "Confidential", settings); // String search
Console.WriteLine($"Text found: {isFound}");

// Regex search example:
bool regexFound = ocr.ImageHasText(img1, @"\d{3}-\d{2}-\d{4}", settings); // e.g., US SSN pattern
Console.WriteLine($"Regex found: {regexFound}");

int similarity = ocr.CompareImageTexts(img1, img2, settings, true); // true = case-insensitive
Console.WriteLine($"Image text similarity: {similarity}%");

try
{
    AsposeOcr ocr = new AsposeOcr();
    bool found = ocr.ImageHasText(img1, "PII", settings);
    int sim = ocr.CompareImageTexts(img1, img2, settings, false);
}
catch (Exception ex)
{
    Console.WriteLine($"Error: {ex.Message}");
}

// Example: Search for a pattern in all images in a folder
foreach (string file in Directory.GetFiles("./archive", "*.png"))
{
    bool found = ocr.ImageHasText(file, "Confidential", settings);
    if (found) { Console.WriteLine($"Found in: {file}"); }
}
