Tutorial de ImageMagick (1.ª gen.)


En este tutorial se muestra cómo usar funciones de Cloud Run, la API Cloud Vision e ImageMagick para detectar y desenfocar imágenes ofensivas que se suban a un segmento de Cloud Storage.

Objetivos

  • Despliega una función de Cloud Run en segundo plano activada por almacenamiento.
  • Usa la API Cloud Vision para detectar contenido violento o para adultos.
  • Usa ImageMagick para difuminar imágenes ofensivas.
  • Prueba la función subiendo una imagen de un zombi carnívoro.

Costes

En este documento, se utilizan los siguientes componentes facturables de Google Cloud:

  • Cloud Run functions
  • Cloud Storage
  • Cloud Vision

Para generar una estimación de costes basada en el uso previsto, utiliza la calculadora de precios.

Los usuarios nuevos Google Cloud pueden disfrutar de una prueba gratuita.

Antes de empezar

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    Go to project selector

  3. Verify that billing is enabled for your Google Cloud project.

  4. Enable the Cloud Functions, Cloud Build, Cloud Storage, and Cloud Vision APIs.

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

    Enable the APIs

  5. Install the Google Cloud CLI.

  6. Si utilizas un proveedor de identidades (IdP) externo, primero debes iniciar sesión en la CLI de gcloud con tu identidad federada.

  7. Para inicializar gcloud CLI, ejecuta el siguiente comando:

    gcloud init
  8. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

  11. Install the Google Cloud CLI.

  12. Si utilizas un proveedor de identidades (IdP) externo, primero debes iniciar sesión en la CLI de gcloud con tu identidad federada.

  13. Para inicializar gcloud CLI, ejecuta el siguiente comando:

    gcloud init
  14. Si ya tienes instalada la CLI de gcloud, actualízala ejecutando el siguiente comando:

    gcloud components update
  15. Prepara tu entorno de desarrollo.
  16. Visualizar el flujo de datos

    El flujo de datos en la aplicación del tutorial de ImageMagick consta de varios pasos:

    1. Se sube una imagen a un segmento de Cloud Storage.
    2. La función analiza la imagen mediante la API Vision.
    3. Si se detecta contenido violento o para adultos, la función usa ImageMagick para desenfocar la imagen.
    4. La imagen desenfocada se sube a otro segmento de Cloud Storage para usarla.

    Preparar la aplicación

    1. Crea un segmento de Cloud Storage para subir imágenes. Para ello, sustituye YOUR_INPUT_BUCKET_NAME por un nombre de segmento único a nivel mundial:

      gcloud storage buckets create gs://YOUR_INPUT_BUCKET_NAME
    2. Crea un segmento de Cloud Storage para recibir las imágenes desenfocadas, donde YOUR_OUTPUT_BUCKET_NAME es un nombre de segmento único a nivel global:

      gcloud storage buckets create gs://YOUR_OUTPUT_BUCKET_NAME
    3. Clona el repositorio de aplicaciones de muestra en la máquina local:

      Node.js

      git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git

      También puedes descargar el ejemplo como un archivo ZIP y extraerlo.

      Python

      git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git

      También puedes descargar el ejemplo como un archivo ZIP y extraerlo.

      Go

      git clone https://github.com/GoogleCloudPlatform/golang-samples.git

      También puedes descargar el ejemplo como un archivo ZIP y extraerlo.

      Java

      git clone https://github.com/GoogleCloudPlatform/java-docs-samples.git

      También puedes descargar el ejemplo como un archivo ZIP y extraerlo.

      Ruby

      git clone https://github.com/GoogleCloudPlatform/ruby-docs-samples.git

      También puedes descargar el ejemplo como un archivo ZIP y extraerlo.

    4. Cambia al directorio que contiene el código de ejemplo de Cloud Run Functions:

      Node.js

      cd nodejs-docs-samples/functions/imagemagick/

      Python

      cd python-docs-samples/functions/imagemagick/

      Go

      cd golang-samples/functions/imagemagick/

      Java

      cd java-docs-samples/functions/imagemagick/

      Ruby

      cd ruby-docs-samples/functions/imagemagick/

    Información sobre el código

    Importar dependencias

    La aplicación debe importar varias dependencias para interactuar con los servicios deGoogle Cloud , ImageMagick y el sistema de archivos:

    Node.js

    const gm = require('gm').subClass({imageMagick: true});
    const fs = require('fs').promises;
    const path = require('path');
    const vision = require('@google-cloud/vision');
    
    const {Storage} = require('@google-cloud/storage');
    const storage = new Storage();
    const client = new vision.ImageAnnotatorClient();
    
    const {BLURRED_BUCKET_NAME} = process.env;

    Python

    import os
    import tempfile
    
    from google.cloud import storage, vision
    from wand.image import Image
    
    storage_client = storage.Client()
    vision_client = vision.ImageAnnotatorClient()

    Go

    
    // Package imagemagick contains an example of using ImageMagick to process a
    // file uploaded to Cloud Storage.

    )
    
    // Global API clients used across function invocations.
    var (
    	storageClient *storage.Client
    	visionClient  *vision.ImageAnnotatorClient
    )
    
    func init() {
    	// Declare a separate err variable to avoid shadowing the client variables.
    	var err error
    
    	storageClient, err = storage.NewClient(context.Background())
    	if err != nil {
    		log.Fatalf("storage.NewClient: %v", err)
    	}
    
    	visionClient, err = vision.NewImageAnnotatorClient(context.Background())
    	if err != nil {
    		log.Fatalf("vision.NewAnnotatorClient: %v", err)
    	}
    }

    }

    Ruby

    require "functions_framework"
    
    FunctionsFramework.on_startup do
      set_global :storage_client do

    end

    Analizar imágenes

    La siguiente función se invoca cuando se sube una imagen al segmento de Cloud Storage que has creado para almacenar imágenes. La función usa la API Vision para detectar contenido violento o para adultos en las imágenes subidas.

    Node.js

    // Blurs uploaded images that are flagged as Adult or Violence.
    exports.blurOffensiveImages = async event => {
      // This event represents the triggering Cloud Storage object.
      const object = event;
    
      const file = storage.bucket(object.bucket).file(object.name);
      const filePath = `gs://${object.bucket}/${object.name}`;
    
      console.log(`Analyzing ${file.name}.`);
    
      try {
        const [result] = await client.safeSearchDetection(filePath);
        const detections = result.safeSearchAnnotation || {};
    
        if (
          // Levels are defined in https://cloud.google.com/vision/docs/reference/rest/v1/AnnotateImageResponse#likelihood
          detections.adult === 'VERY_LIKELY' ||
          detections.violence === 'VERY_LIKELY'
        ) {
          console.log(`Detected ${file.name} as inappropriate.`);
          return await blurImage(file, BLURRED_BUCKET_NAME);
        } else {
          console.log(`Detected ${file.name} as OK.`);
        }
      } catch (err) {
        console.error(`Failed to analyze ${file.name}.`, err);
        throw err;
      }
    };

    Python

    # Blurs uploaded images that are flagged as Adult or Violence.
    def blur_offensive_images(data, context):
        file_data = data
    
        file_name = file_data["name"]

    Desenfoque de imágenes

    La siguiente función se llama cuando se detecta contenido violento o para adultos en una imagen subida. La función descarga la imagen ofensiva, usa ImageMagick para difuminarla y, a continuación, sube la imagen difuminada sobre la original.

    Node.js

    // Blurs the given file using ImageMagick, and uploads it to another bucket.
    const blurImage = async (file, blurredBucketName) => {
      const tempLocalPath = `/tmp/${path.parse(file.name).base}`;
    
      // Download file from bucket.
      try {
        await file.download({destination: tempLocalPath});
    
        console.log(`Downloaded ${file.name} to ${tempLocalPath}.`);
      } catch (err) {
        throw new Error(`File download failed: ${err}`);
      }
    
      await new Promise((resolve, reject) => {
        gm(tempLocalPath)
          .blur(0, 16)
          .write(tempLocalPath, (err, stdout) => {
            if (err) {
              console.error('Failed to blur image.', err);
              reject(err);

              console.log(`Blurred image: ${file.name}`);
              resolve(stdout);
            }
          });
      });
    
      // Upload result to a different bucket, to avoid re-triggering this function.
      const blurredBucket = storage.bucket(blurredBucketName);
    
      // Upload the Blurred image back into the bucket.
      const gcsPath = `gs://${blurredBucketName}/${file.name}`;
      try {
        await blurredBucket.upload(tempLocalPath, {destination: file.name});
        console.log(`Uploaded blurred image to: ${gcsPath}`);
      } catch (err) {
        throw new Error(`Unable to upload blurred image to ${gcsPath}: ${err}`);

        # Upload result to a second bucket, to avoid re-triggering the function.

        blur_bucket_name = ENV["BLURRED_BUCKET_NAME"]
        blur_bucket = global(:storage_client).bucket blur_bucket_name
        blur_bucket.create_file tempfile.path, file_name

      ensure
        # Ruby will remove the temp file when garbage collecting the object,

    end

    Desplegar la función

    Para desplegar la función con un activador de almacenamiento, ejecuta el siguiente comando en el directorio que contiene el código de ejemplo (o el archivo pom.xml en el caso de Java):

    Node.js

    gcloud functions deploy blurOffensiveImages \
    --no-gen2 \
    --runtime=RUNTIME \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    Python

    gcloud functions deploy blur_offensive_images \
    --no-gen2 \
    --runtime=RUNTIME \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    Go

    gcloud functions deploy BlurOffensiveImages \
    --no-gen2 \
    --runtime=RUNTIME \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    Java

    gcloud functions deploy java-blur-function \
    --no-gen2 \
    --entry-point=functions.ImageMagick \
    --runtime=RUNTIME \
    --memory 512MB \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    C#

    gcloud functions deploy csharp-blur-function \
    --no-gen2 \
    --entry-point=ImageMagick.Function \
    --runtime=RUNTIME \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    Ruby

    gcloud functions deploy blur_offensive_images \
    --no-gen2 \
    --runtime=RUNTIME \
    --trigger-bucket=YOUR_INPUT_BUCKET_NAME \
    --set-env-vars=BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME
    

    Haz los cambios siguientes:

    • RUNTIME: un tiempo de ejecución basado en Ubuntu 18.04 (los tiempos de ejecución posteriores no incluyen compatibilidad con ImageMagick).
    • YOUR_INPUT_BUCKET_NAME: el nombre del segmento de Cloud Storage para subir imágenes.
    • YOUR_OUTPUT_BUCKET_NAME: el nombre del segmento en el que se deben guardar las imágenes borrosas.

    En este ejemplo concreto, no incluyas gs:// como parte de los nombres de los contenedores en el comando deploy.

    Subir una imagen

    1. Sube una imagen ofensiva, como esta de un zombi carnívoro:

      gcloud storage cp zombie.jpg gs://YOUR_INPUT_BUCKET_NAME

      donde YOUR_INPUT_BUCKET_NAME es el segmento de Cloud Storage que has creado anteriormente para subir imágenes.

    2. Consulta los registros para asegurarte de que las ejecuciones se han completado:

      gcloud functions logs read --limit 100
    3. Puedes ver las imágenes desenfocadas en el YOUR_OUTPUT_BUCKET_NAME segmento de Cloud Storage que has creado antes.

    Limpieza

    Para evitar que los recursos utilizados en este tutorial se cobren en tu cuenta de Google Cloud, elimina el proyecto que contiene los recursos o conserva el proyecto y elimina los recursos.

    Eliminar el proyecto

    La forma más fácil de evitar que te cobren es eliminar el proyecto que has creado para el tutorial.

    Para ello, sigue las instrucciones que aparecen a continuación:

    1. In the Google Cloud console, go to the Manage resources page.

      Go to Manage resources

    2. In the project list, select the project that you want to delete, and then click Delete.
    3. In the dialog, type the project ID, and then click Shut down to delete the project.

    Eliminar la función

    Si eliminas funciones de Cloud Run, no se eliminarán los recursos almacenados en Cloud Storage.

    Para eliminar la función que has desplegado en este tutorial, ejecuta el siguiente comando:

    Node.js

    gcloud functions delete blurOffensiveImages 

    Python

    gcloud functions delete blur_offensive_images 

    Go

    gcloud functions delete BlurOffensiveImages 

    Java

    gcloud functions delete java-blur-function 

    Ruby

    gcloud functions delete blur_offensive_images 

    También puedes eliminar funciones de Cloud Run desde la Google Cloud consola.
