// Package computervision implements the Azure ARM Computervision service API version 2.0.
//
// 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.

// AnalyzeImage this operation extracts a rich set of visual features based on the image content. Two input methods are

// Parameters:
// imageURL - a JSON document with a URL pointing to the image that is to be analyzed.
// visualFeatures - a string indicating what visual feature types to return. Multiple values should be
// comma-separated. Valid visual feature types include:Categories - categorizes image content according to a
// taxonomy defined in documentation. Tags - tags the image with a detailed list of words related to the image
// content. Description - describes the image content with a complete English sentence. Faces - detects if
// faces are present. If present, generate coordinates, gender and age. ImageType - detects if image is clipart
// or a line drawing. Color - determines the accent color, dominant color, and whether an image is
// black&white.Adult - detects if the image is pornographic in nature (depicts nudity or a sex act).  Sexually
// suggestive content is also detected.
// details - a string indicating which domain-specific details to return. Multiple values should be
// comma-separated. Valid visual feature types include:Celebrities - identifies celebrities if detected in the
// image.
// language - the desired language for output generation. If this parameter is not specified, the default value
// is "en".Supported languages:en - English, Default. es - Spanish, ja - Japanese, pt - Portuguese,
