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:' } 

请确保替换 为最新的 MediaPipe 版本。

2. 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); } } 

3. 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:' implementation 'androidx.camera:camera-camera2:' implementation 'androidx.camera:camera-lifecycle:' } 

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(); } } 

4. 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.CameraSelector; import androidx.camera.core.ImageAnalysis; import androidx.camera.core.ImageProxy; import androidx.camera.core.ImageAnalyzer; import androidx.camera.core.CameraInfoUnavailableException;
