Android: locating words on the screen. Google ML Kit bounding boxes are off a bit

Asked 2021-Mar-23 at 08:58

I'm trying to find a certain words on the phone screen, and then display a bounding box around them if they are present. I follow these steps:

Capture entire screen contents (with MediaProjection API).
Pass this screenshot to a TextRecognizer object from the Google ML Kit
Check the detected words, in case of match use the Rect returned by the ML Kit to draw on the screen.

It almost works, here is a screenshot of the detection finding and highlighting the word hello on the notepad app:

As you can see the the semi transparent yellow boxed are a not quite on the hellos.

Here are the relevant code samples. Passing the screenshot bitmap to the ML Kit:

The image gets fed into MLKit and displayed on the preview may come with different sizes. Please refer to the mlkit example to see how to scale and map them.

The text recognition of MLkIT does not recognize non-english text

Asked 2020-Dec-15 at 18:02

I implemented the text recognition of MLkit on IOS but it could not recognize non-English text (e.x Arabic text).

It works in English only.

ANSWER

Answered 2020-Dec-15 at 18:02

Update: If it does not need to be completely local (on-device without network), you can try MLKit for cloud, which supports "100+ different languages and scripts.". Firebase Text Recognition

For local inference: Googles 'MLKit text recognition' is based on 'TensorFlow Lite' which uses local models in order to recognize the text. From my researches Google does not state that the predefined model is exclusively working for Latin alphabet. But it seems like that. So you have three options now:

Look for a custom "TensorFlow Lite" model which is trained for arabic alphabet.
Train your own "TensorFlow Lite" model: TensorFlow Lite Model Maker
Find/Train a "Tensor Flow" model (not lite!) and convert it to a "TensorFlow Lite" Model

Xamarin Forms: Return String from Android Activity

Asked 2020-May-25 at 03:02

I'm trying to develop a mobile app in Xamarin Forms...One of the functionalities is text recognition. I need to recognize the text and then send it to another page (xaml). So i made an activity where it does recognize the text but i don't know how to return the string "Resultados" (Results). I tried to do a little search and many suggested that the "OnActivityResult" should return the values...but it doesnt get triggered.

Can anyone help me out what i am doing wrong?

I tried to do a little search and many suggested that the "OnActivityResult" should return the values...but it doesnt get triggered.

You are using OnActivityResult a bit wrong. For example, if you have two Activity, ActivityA and ActivityB, OnActivityResult method in ActivityA, ActivityB need return some value to ActivityA, we can use activityA.StartActivityForResult() to open ActivityB,

ActivityB Use SetResult method to send data to ActivityA.

Flutter app does not stop installing when firebase_database depencancy is added

Asked 2019-Dec-29 at 08:21

I am new to flutter programming and I am building a simple app with firebase ml kit and firebase database. This is a part of my university project to create a mobile wallet. Here what i am doing is scanning the credit/debit card for card details by ml vision kit and storing it in firebase databse. Scanning part is running propperly and when I add the database dependency The app is not even installing. When debugging it gives Note: C:\Users\SKYWALKER\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\firebase_core-0.2.5+1\android\src\main\java\io\flutter\plugins\firebase\core\FirebaseCorePlugin.java uses unchecked or unsafe operations.

ANSWER

Answered 2019-Dec-29 at 08:21

I don't see a firebase_auth in your pubspec.yaml file. Assuming that you have added firebase to your app ( how to add firebase to app), each user needs to be authenticated to firebase before using firebase_database ( I will recommend using cloud_firestore over firebase_database if the speed of response of database is important for you ). Use firebase_core to enable connection to multiple Firebase apps.

Note that for the latest version of firebase_auth to work, your project needs to be AndroidX complaint (enter link description here).
