The projects in this code are quickstarts that show how to use Computer Vision SDK for local and remote images

Contents

File/folder	Description
AnalyzeImage	Analyzes image on specified visual parameters
DetectObjects	Detects objects in an image
BatchReadFile	Looks for printed or handwritten text in a file (accepts PDFs too)
OCR	Performs OCR on the image
RegionOfInterest	Gets area of interest
TagImage	Descriptive tags for an image
Describe Image	A caption for the image
Recognize Text	Uses RecognizeText for printed and handwritten text
Get Thumbnail	Gets a recommended thumbnail for an image given a target size
ComputerVision.sln	The Visual Studio solution with the above as projects
readme.md	This README file.

Prerequisites

• Visual Studio 2015 or higher
• An Azure Subscription Key

Setup

1. Clone or download this sample repository
2. Open the solution ComputerVision_SDK.sln in Visual Studio
3. Download the images from this repo and add the Images folder as content to each project. Alternatively modify the imageFilePath in all projects to reflect the path of an appropriate local image.

Running the samples

1. Right-click on the relavant project (detectObjects, extractText, etc) and click on 'Set as StartUp Project'
2. In 'Program.cs' , update the line private const string subscriptionKey = "<your training key here>"; with your subscription key. For example, if your subscription key is 0123456789abcdef0123456789ABCDEF, then the line should look like c# private const string subscriptionKey = "0123456789abcdef0123456789ABCDEF";
3. Update the endpoint with the region you generated your endpoint for. For example, if you are using the westcentralus endpoint, you should change the line public const string endpoint = "https://westus.api.cognitive.microsoft.com"; to public const string endpoint = "https://westcentralus.api.cognitive.microsoft.com";
4. (Optional) Change the remote image URL
5. (Optional) Comment out visual parameters not needed for AnalyzeImage
6. Hit F5 or build the solution
