我試圖將圖像文件轉換爲使用tess4j maven依賴項的文本。
依賴在pom.xml中: -不支持的圖像格式。可能需要安裝JAI圖像I/O包
<!-- OCR dependency -->
<dependency>
<groupId>net.sourceforge.tess4j</groupId>
<artifactId>tess4j</artifactId>

我的代碼: -
public String convertImageToText(String imageFilePath) throws TesseractException {
File imageFile = new File("imageFilePath");
ITesseract iTesseract = new Tesseract();
ImageIO.scanForPlugins();
String result = iTesseract.doOCR(imageFile);
System.out.println("Converted text is: "+result);
return result;
}
然而,當我嘗試執行我的計劃,我總是會遇到以下異常:
Exception in thread "main" net.sourceforge.tess4j.TesseractException: java.lang.RuntimeException: Unsupported image format. May need to install JAI Image I/O package.

所有需要的依賴像jai,lept4j等存在於我的倉庫中。此外,我已嘗試在此論壇上提出的所有解決方案,但我無法解決此錯誤。
任何幫助,將不勝感激。
感謝
更新:此附加文件 - Jpg file
你試圖閱讀什麼類型的圖像文件? – VGR
我試着用JPG和PNG文件。兩種格式都有相同的錯誤。 – Anuja
你可以發佈一個有問題的圖像文件imgur,所以我們可以嘗試加載ImageIO? – VGR
