Service presentation
--------------------

[](#service-presentation)

With [Microsoft's Computer Vision API](https://www.microsoft.com/cognitive-services/en-us/computer-vision-api) users can analyze images to use optical character recognition to identify text found in images, directly from a Symfony project.

The cloud-based Computer Vision API provides developers with access to advanced algorithms for processing images and returning information. By uploading an image or specifying an image URL, Microsoft Computer Vision algorithms can analyze visual content in different ways based on inputs and user choices.

The OCR is available:

- as a service, available in your Symfony's dependency injection container
- as a command line tool, with arguments and options (see below)

Supported locales
-----------------

[](#supported-locales)

The 21 languages supported by OCR are Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, and Turkish.

Accuracy
--------

[](#accuracy)

The accuracy of text recognition depends on the quality of the image. An inaccurate reading may be caused by the following:

- Blurry images
- Handwritten or cursive text
- Artistic font styles
- Small text size
- Complex backgrounds, shadows or glare over text or perspective distortion
- Oversized or missing capital letters at the beginnings of words
- Subscript, superscript, or strikethrough text

Limitations
-----------

[](#limitations)

On photos where text is dominant, false positives may come from partially recognized words. On some photos, especially photos without any text, precision can vary a lot depending on the type of image.

- Small text size
- Complex backgrounds, shadows or glare over text or perspective distortion
- Oversized or missing capital letters at the beginnings of words
- Subscript, superscript, or strikethrough text
