The clarifai package

[Tags:library, mit]

Provides functionality for interacting with Clarifai's Image Tagging API. Users need a Clarifai account to use this, as the endpoints require an access token.

clarifai-hs

Haskell API Client for <a href="http://www.clarifai.com">Clarifai</a>.

Clarifai provides image/video recognition services, and this library provides a web client to their API.

All endpoints other than the <em>feedback</em> endpoint are implemented. This includes

  • /info
  • /token
  • /tag

Installation

<pre>cabal install clarifai</pre>

Example Usage

Authorization

First create an App and then call the authorize function to authenticate your application. You must provide your client id and client secret.


import Network.Clarifai
import Data.Either

clientID = "id"
clientSecret = "secret"

main = do
  let myApp = App clientID clientSecret
  resp <- authorize myApp

Then you can check the response for errors, or use the access token it provides back in the form of a Client.

Getting API Info

-- Omitted previous code
main = do
  -- Be sure to check for errors
  let client = head $ rights [resp]
  infoResponse <- info client

If there are no errors, you will get back an Info containing various information about the statistics and limits of the Clarifai API, like maximum video size, maximum image size, etc. You can use this verify any files you may want to tag, before you send a tagging request.

Verification

When going to verify batch sizes, it is important not to mix and match between videos and images. The batch sizes for images and videos are different, so you cannot verify the sizes of the batches together even though you can send them in the same request. I don't do any differentiating between what kind of file the FilePath points to.

If you are calling the verifyFiles function, however, you can have a list of both videos AND images, as long as the extensions of each FilePath indicate the type of the file.

-- Omitted previous code
main = do
  -- Be sure to check for errors
  let apiInfo = head $ rights [infoResponse]
  let filePaths = [filePath1, filePath2, filePath3]

  -- Verify the image batch size
  -- The return value is a Bool indicating whether your list is of appropriate size for the API.
  verifyImageBatchSize apiInfo filePaths

  -- Verify the sizes of the files in the list. As long as each FilePath indicates whether the file is a video or an image,
  -- the size of the file will be checked to make sure it is within the appropriate bounds according to the API Info.
  verifyFiles infoData fileNames

Tagging

We can send a tag request with our list of FilePaths. I've omitted any steps where we may have filtered out which files verifyFiles marked as inappropriate for the request.

-- Omitted previous code
tagResponse <- tag client fileNames
