// Package computervision implements the Azure ARM Computervision service API version 1.0.
//
// The Computer Vision API provides state-of-the-art algorithms to process images and return information. For example,
// it can be used to determine if an image contains mature content, or it can be used to find all the faces in an
// image.  It also has other features like estimating dominant and accent colors, categorizing the content of images,
// and describing an image with complete English sentences.  Additionally, it can also intelligently generate images
// thumbnails for displaying large images effectively.
