android mediapipe 如何处理图像

Android MediaPipe 是一个用于构建实时计算机视觉管道的框架，可以处理图像、视频和其他媒体数据

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

请确保替换 <latest_version> 为最新的 MediaPipe 版本。

  1. 创建 MediaPipe 图像处理管道： 首先，创建一个继承自 mp.Graph 的类，然后向其中添加图像处理节点。例如，以下代码创建了一个简单的图像处理管道，其中包括一个图像缩放和一个图像旋转节点：
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();
        // 添加图像缩放节点
        graph.addNode(new ImageScaler());
        // 添加图像旋转节点
        graph.addNode(new ImageTransformer());
    }

    public void processImage(Image image) {
        graph.run(image);
    }
}
  1. 从摄像头捕获图像： 要处理来自摄像头的图像，请使用 CameraX 库。首先，添加以下依赖项到您的 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>'
}

接下来，创建一个继承自 CameraX.ViewCapture 的类，并重写 onCaptureResult 方法以处理捕获的图像：

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();
        // 处理图像
        imageProcessingGraph.processImage(image);

        imageProxy.close();
    }
}
  1. 将摄像头与图像处理视图关联： 最后，将摄像头与图像处理视图关联起来。在您的 Activity 或 Fragment 中，执行以下操作：

import androidx.camera.core.ImageProxy;
