// Package computervision implements the Azure ARM Computervision service API version 2.1.
//
// 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 supported -- (1) Uploading an image or (2) specifying an image URL. Within your request, there
// is an optional parameter to allow you to choose which features to return. By default, image categories are returned
// in the response.
// A successful response will be returned in JSON. If the request failed, the response will contain an error code and a
// message to help understand what went wrong.
// 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), or is gory (depicts
// extreme violence or blood). Sexually suggestive content (aka racy content) is also detected. Objects -
// detects various objects within an image, including the approximate location. The Objects argument is only
// available in English. Brands - detects various brands within an image, including the approximate location.
// The Brands argument is only available in English.
// 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, Landmarks - identifies notable landmarks 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,
// zh - Simplified Chinese.
// descriptionExclude - turn off specified domain models when generating the description.
