How to implement image classification/ labelling method in your Android App?

In this video we will see how to implement image classification/ labelling method in your Android App.

It uses com.google.mlkit:image-labeling dependency for the same. The details of this library is also shared in the below google developer page: https://developers.google.com/codelabs/tflite-computer-vision-mobile#0

In this tutorial it uses 2 images - flower and finger - for demonstrating the functionality of the code.

However, the main Java code is copied below also for reference:


package com.programmerworld.imageclassificationapp;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

import com.google.android.gms.tasks.OnSuccessListener;
import com.google.mlkit.vision.common.InputImage;
import com.google.mlkit.vision.label.ImageLabel;
import com.google.mlkit.vision.label.ImageLabeler;
import com.google.mlkit.vision.label.ImageLabeling;
import com.google.mlkit.vision.label.defaults.ImageLabelerOptions;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;

public class MainActivity extends AppCompatActivity {

private TextView textView;
private ImageView imageView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

textView = findViewById(R.id.textView);
imageView = findViewById(R.id.imageView);
}

public void buttonImageLabel(View view) throws IOException {
InputStream inputStream = getAssets().open("finger.jpg");
Bitmap bitmapImage = BitmapFactory.decodeStream(inputStream);
imageView.setImageBitmap(bitmapImage);
ImageLabeler imageLabeler = ImageLabeling.getClient(ImageLabelerOptions.DEFAULT_OPTIONS);
InputImage inputImage = InputImage.fromBitmap(bitmapImage, 0);

imageLabeler.process(inputImage).addOnSuccessListener(new OnSuccessListener ANGULAR List ANGULAR ImageLabel ANGULAR ANGULAR () {
@Override
public void onSuccess(List ANGULAR ImageLabel ANGULAR imageLabels) {
String stringImageRecognition = "";
for (ImageLabel imageLabel: imageLabels){
String stingLabel = imageLabel.getText();
Float floatConfidence = imageLabel.getConfidence();

stringImageRecognition += stingLabel + ": " + floatConfidence.toString() + "; ";
}
textView.setText(stringImageRecognition);
}
});
}
}
