MediaPipe是一個用于實時計算機視覺和機器學習管道的開源庫,可以在Android平臺上使用。要在Android上實現MediaPipe,您需要遵循以下步驟:
build.gradle
文件中添加以下依賴項:dependencies {
implementation 'com.google.mediapipe:mediapipe:<version>'
}
請確保替換<version>
為最新的MediaPipe版本號。
MediaPipeExample.java
或MediaPipeExample.kt
。MediaPipe
實例并配置所需的組件,例如ImageReader
、Encoder
和Decoder
。import com.google.mediapipe.framework.MediaPipe;
import com.google.mediapipe.framework.Pipeline;
import com.google.mediapipe.image.ImageReader;
import com.google.mediapipe.video.VideoEncoder;
import com.google.mediapipe.video.VideoDecoder;
public class MediaPipeExample {
private Pipeline pipeline;
public MediaPipeExample() {
pipeline = new Pipeline.Builder().build();
// Configure components here
}
}
import android.graphics.Bitmap;
import android.graphics.ImageFormat;
import android.media.ImageReader;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
private MediaPipeExample mediaPipeExample;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPipeExample = new MediaPipeExample();
// Start the pipeline here
}
@Override
protected void onResume() {
super.onResume();
if (pipeline != null) {
pipeline.start();
}
}
@Override
protected void onPause() {
super.onPause();
if (pipeline != null) {
pipeline.stop();
}
}
}
Encoder
和Decoder
。import android.graphics.Bitmap;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
// ...
@Override
protected void onResume() {
super.onResume();
if (pipeline != null) {
pipeline.start();
// Start reading output data here
}
}
@Override
protected void onPause() {
super.onPause();
if (pipeline != null) {
pipeline.stop();
// Stop reading output data here
}
}
}
以上是在Android上實現MediaPipe的基本步驟。您可以根據項目需求進一步定制和優化MediaPipe管道。
