使用Amazon Rekognition服务获取图像中的文本时出现错误

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'，但是对于httpclient'gradle'无法解决其依赖关系。 / p>

我写错了吗？我还可以在图像中使用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

一个单词是一个或多个ISO基本拉丁字母字符，不是用空格隔开。 DetectText最多可以在一张图像中检测50个单词。

在撰写本文时，尚不支持阿拉伯语。

希望有帮助。
