IBM Watson Visual Recognition API

This PHP library provides integration with the IBM Watson Visual Recognition service.

See API documentation.

Usage

The structure of this library was inspired by the Omnipay suite of packages.

One of the things that this means is the library doesn't hide away that fact that API requests are being made. For each API request, the request should be created with parameters passed in, sent and then response reviewed.

All requests are available via the Client.

use Bobbyshaw\WatsonVisualRecognition\Client;
use Bobbyshaw\WatsonVisualRecognition\Classifier;

$client = new Client();

The client should then be initialized with parameters, e.g. username and password (your IBM Watson Service credentials).

$client->initialize(['username' => 'abcdef', 'password' => '12356])

The following can be used find default parameters

$client->getDefaultParameters();

Each method matches an API request and returns a request object ready to be sent. Most of the time you'll want to send the request straight away.

$request = $client->getClassifiers();
$response = $request->send();

Each response has a class which helps to manage the response, e.g with the Classifier and Image classes.

/** @var Classifier[] $classifiers */
$classifiers = $response->getClassifiers();
