How to crop an image to the face in Javascript

Smart image cropping can be a very useful feature, for example in creating profile pictures. The Deep Learning requirement for this can be a bit daunting, considering the hours of work and training time needed to get good results. We already have this set up, however, and have it packaged in a shiny API that’s all ready to go. Here’s how to use it.

First install our API client, which needs to have this script tag in your HTML file.

<script src=""></script>

And now simply call our function, as we see below. There is a also faceCropFirst, which creates a square cropped photo.

var CloudmersiveImageApiClient = require('cloudmersive-image-api-client');var defaultClient = CloudmersiveImageApiClient.ApiClient.instance;// Configure API key authorization: Apikeyvar Apikey = defaultClient.authentications['Apikey'];Apikey.apiKey = 'YOUR API KEY';// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)//Apikey.apiKeyPrefix = 'Token';var apiInstance = new CloudmersiveImageApiClient.FaceApi();var imageFile = "/path/to/file"; // File | Image file to perform the operation on.  Common file formats such as PNG, JPEG are supported.var callback = function(error, data, response) {if (error) {console.error(error);} else {console.log('API called successfully. Returned data: ' + data);}};apiInstance.faceCropFirstRound(imageFile, callback);

OK, done. Yup, it’s really that easy. Let’s test it out on this image.
