Overview

Ruby Client for Google Cloud Vision API (Alpha)

Google 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.

Product Documentation

Quick Start

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

Installation

$ gem install google-cloud-vision

Preview

ImageAnnotatorClient

require "google/cloud/vision"

image_annotator_client = Google::Cloud::Vision.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)

Class Method Details

.new(project_id: nil, credentials: nil, scope: nil, timeout: nil, client_config: nil, project: nil, keyfile: nil) ⇒ `Google::Cloud::Vision::Project`

Creates a new object for connecting to the Vision service. Each call creates a new connection.

Examples:

require "google/cloud/vision"

vision = Google::Cloud::Vision.new

image = vision.image "path/to/landmark.jpg"

landmark = image.landmark
landmark.description #=> "Mount Rushmore"

Parameters:

project_id (String) —
Project identifier for the Vision service you are connecting to. If not present, the default project for the credentials is used.
credentials (String, Hash, Google::Auth::Credentials) —
The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials)
scope (String, Array<String>) —
The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

The default scope is:
- https://www.googleapis.com/auth/cloud-platform
timeout (Integer) —
Default timeout to use in requests. Optional.
client_config (Hash) —
A hash of values to override the default behavior of the API client. Optional.
project (String) —
Alias for the project_id argument. Deprecated.
keyfile (String) —
Alias for the credentials argument. Deprecated.

Returns:

(Google::Cloud::Vision::Project)
