Android Question TextRecognition based on MLKit on a continuous loop

[gregchao]

Is there a way to make this text recognition work on a continuous loop? When the User is satisfied with the result, he/she stops the loop...

[B4X] TextRecognition based on MLKit

This is a B4A + B4i solution. It recognizes text in images based on Google ML Kit. Dependencies: - B4i (local Mac only): https://www.b4x.com/b4i/files/MLKit.zip The files and folders should be unzipped into Libs/Extra/MLKit Don't miss: - B4i dependencies + #PlistExtra (for MediaChooser)...

I'm missing some context here. I guess that you want to get the camera preview frames and recognize text.
See this example: https://www.b4x.com/android/forum/t...on-google-play-services-vision.89705/#content

I tried the camera preview and it is not a good idea. The delay time of the text recognition is too long so I abandoned the idea.

I ran into a second issue. The example app itself takes a long time to load. It is 134Mb on my iPhone. Is there a way to trim it down?...possibly trading away some features. I am only interested in Latin so I deleted the Chinese module already.

Remove these declarations:

#AdditionalLib: MLKitTextRecognitionChinese.framework.3
#AdditionalLib: MLKitTextRecognitionDevanagari.framework.3
#AdditionalLib: MLKitTextRecognitionJapanese.framework.3
#AdditionalLib: MLKitTextRecognitionKorean.framework.3

And Files\Special\ all bundles except of the LatinOCR.

This is for B4i.

Those declarations are not in the example. Here are the declarations:

#AdditionalLib: MLKitCommon.framework.3
#AdditionalLib: MLKitBarcodeScanning.framework.3
#AdditionalLib: MLImage.framework.3
#AdditionalLib: MLKitVision.framework.3
#AdditionalLib: MLKitImageLabeling.framework.3
#AdditionalLib: MLKitImageLabelingCommon.framework.3
#AdditionalLib: MLKitImageLabelingCustom.framework.3
#AdditionalLib: MLKitObjectDetection.framework.3
#AdditionalLib: MLKitObjectDetectionCommon.framework.3
#AdditionalLib: MLKitObjectDetectionCustom.framework.3
#AdditionalLib: MLKitVisionKit.framework.3
#AdditionalLib: MLKitXenoCommon.framework.3
#AdditionalLib: PromisesObjC.framework.3
#AdditionalLib: GTM
#AdditionalLib: sqlite3
#AdditionalLib: GTMSessionFetcher.framework.3
#AdditionalLib: GoogleUtilitiesComponents.framework.3
#AdditionalLib: Accelerate.framework
#AdditionalLib: GoogleDataTransport.framework.3
#AdditionalLib: MLKitTextRecognitionCommon.framework.3
#AdditionalLib: MLKitTextRecognition.framework.3

Can I remove any of these or are they all necessary?
