android mediapipe 如何處理圖像

Android MediaPipe 是一個用于構建實時計算機視覺管道的框架，可以處理圖像、視頻和其他媒體數據

  1. 添加依賴項： 在您的 build.gradle 文件中添加以下依賴項：
dependencies {
    implementation 'com.google.mediapipe:mediapipe:<latest_version>'
}

請確保替換 <latest_version> 為最新的 MediaPipe 版本。

  1. 創建 MediaPipe 圖像處理管道： 首先，創建一個繼承自 mp.Graph 的類，然后向其中添加圖像處理節點。例如，以下代碼創建了一個簡單的圖像處理管道，其中包括一個圖像縮放和一個圖像旋轉節點：
import com.google.mediapipe.framework.Graph;
import com.google.mediapipe.framework.Image;
import com.google.mediapipe.modules.core.ImageScaler;
import com.google.mediapipe.modules.core.ImageTransformer;

public class ImageProcessingGraph {
    private Graph graph;

    public ImageProcessingGraph() {
        graph = new Graph();
        // 添加圖像縮放節點
        graph.addNode(new ImageScaler());
        // 添加圖像旋轉節點
        graph.addNode(new ImageTransformer());
    }

    public void processImage(Image image) {
        graph.run(image);
    }
}
  1. 從攝像頭捕獲圖像： 要處理來自攝像頭的圖像，請使用 CameraX 庫。首先，添加以下依賴項到您的 build.gradle 文件：
dependencies {
    implementation 'androidx.camera:camera-core:<latest_version>'
    implementation 'androidx.camera:camera-camera2:<latest_version>'
    implementation 'androidx.camera:camera-lifecycle:<latest_version>'
}

接下來，創建一個繼承自 CameraX.ViewCapture 的類，并重寫 onCaptureResult 方法以處理捕獲的圖像：

import androidx.camera.core.ImageProxy;
import androidx.camera.core.ViewCapture;
import androidx.camera.core.ImageAnalysis;
import androidx.camera.core.ImageProxy.PlaneProxy;

public class ImageCaptureView extends ViewCapture {
    private ImageProcessingGraph imageProcessingGraph;

    public ImageCaptureView(ImageProcessingGraph imageProcessingGraph) {
        this.imageProcessingGraph = imageProcessingGraph;
    }

    @Override
    public void onCaptureResult(ImageProxy imageProxy, int cameraId) {
        if (imageProxy == null || imageProxy.getImage() == null) {
            return;
        }

        Image image = imageProxy.getImage();
        // 處理圖像
        imageProcessingGraph.processImage(image);

        imageProxy.close();
    }
}
  1. 將攝像頭與圖像處理視圖關聯： 最后，將攝像頭與圖像處理視圖關聯起來。在您的 Activity 或 Fragment 中，執行以下操作：

import androidx.camera.core.ImageAnalysis;
import androidx.camera.core.ImageProxy;
