Vision.jl

A Julia package for easily interacting with the Google Vision API.

The package currently implements the following features:

1. makeRequestBody - creates a request body for the Google Vision API from either a base 64 encoded image or a URI to an image containing one or more features.

2. visionFeature - creates a VisionFeature object for use in the request body.

3. getResponse - sends a request to the Google Vision API and returns the response.

4. parseFeatures - parses the response from the Google Vision API, currently only supports textAnnotations

How to use

Install "Vision" from the Julia package manager.

] add Vision

Export your google API key to JULIA_VISION_API_KEY or manually override the URL used by getResponse

Example code snippets

Using base64 encoded images

using Vision
using Base64

image = base64encode(open("example.jpg", "r"))

requestBody = makeRequestBody(image, visionFeature("DOCUMENT_TEXT_DETECTION"))

response = getResponse(requestBody)

println(parseFeatures(response))

Using URI's

using Vision
using URIs

requestBody = makeRequestBody(
    URI("https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Julia_Programming_Language_Logo.svg/1920px-Julia_Programming_Language_Logo.svg.png"),
    [
        visionFeature("LABEL_DETECTION", 50),
        visionFeature("TEXT_DETECTION", 50),
        visionFeature("LOGO_DETECTION", 1),
    ]
)
response = getResponse(requestBody)

println(parseFeatures(response))
