Amazon Rekognition for text dertection text in image

Question

我在使用Amazon Rekognition服务获取图像中的文本时出错

这是我的代码

String photo = Environment.getExternalStorageDirectory().getAbsolutePath()+"/test/testImage.png";
ByteBuffer imageBytes;
try  {
InputStream inputStream = new FileInputStream(new File(photo));
imageBytes = ByteBuffer.wrap(IOUtils.toByteArray(inputStream));
Logger.getLogger("org.apache.http").setLevel(Level.FINEST);
Logger.getLogger("com.amazonaws").setLevel(Level.FINEST);
ImageView imageView = findViewById(R.id.image);
Glide.with(this)
.load(photo)
.into(imageView);
AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();

DetectTextRequest  request = new DetectTextRequest ()
.withImage(new Image()
.withBytes(imageBytes));

DetectTextResult  result = rekognitionClient.detectText(request);
List<TextDetection> textDetections = result.getTextDetections();
Log.i(TAG,"Detected lines and words for " + photo);
for (TextDetection  text: textDetections) {
Log.i(TAG,"Detected: " + text.getDetectedText());
Log.i(TAG,"Confidence: " + text.getConfidence().toString());

}
}
catch (Exception e)
{
Log.e(TAG,e.toString());
}

我尝试使用库'org.apache.httpcomponents：httpmime：4.3.6'和'org.apache.httpcomponents：httpclient-android：4.3.6'，但对于httpclient，'gradle'无法解析其依赖关系。

我写错了什么吗？ 我也可以使用图像中的文本从本地存储中获取图像吗？ 它是否支持阿拉伯语？

Answer 1

如文档中所述，当前算法只能识别，

https://en.wikipedia.org/wiki/ISO_basic_Latin_alphabet

大写和小写英文字符。

文本检测：

https://docs.aws.amazon.com/rekognition/latest/dg/text-detection.html

单词是一个或多个不是 ISO 基本拉丁字母的字符 用空格分隔。检测文本最多可以检测图像中的 50 个单词。

在撰写本文时，尚不支持阿拉伯语。

希望对您有所帮助。
