Overview

Ruby Client for Cloud Vision API (Alpha)

Cloud Vision API: Integrates Google Vision features, including image labeling, face, logo, and landmark detection, optical character recognition (OCR), and detection of explicit content, into applications.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Cloud Vision API.
  4. Setup Authentication.

Installation

$ gem install google-cloud-vision

Migration Guide

The 0.32.0 release introduced breaking changes relative to the previous release, 0.31.0. For more details and instructions to migrate your code, please visit the migration guide.

Preview

ImageAnnotatorClient

require "google/cloud/vision"

image_annotator_client = Google::Cloud::Vision::ImageAnnotator.new
gcs_image_uri = "gs://gapic-toolkit/President_Barack_Obama.jpg"
source = { gcs_image_uri: gcs_image_uri }
image = { source: source }
type = :FACE_DETECTION
features_element = { type: type }
features = [features_element]
requests_element = { image: image, features: features }
requests = [requests_element]
response = image_annotator_client.batch_annotate_images(requests)

Next Steps

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end
