Hi
in order to load the VisionAPI-WPF-Samples.sln visual studio tries to load SampleUserControlLibrary.sln as a dependency which is not exit in project file there for the project cant build.

Please, Merge this repo with https://github.com/Microsoft/Cognitive-Vision-DotNetCore and .net standard for client libraries.
not it's 100% code clone.

The code uses the following endpoint:

https://westcentralus.api.cognitive.microsoft.com/vision/v1.0

However I'm an European and therefore use:

https://westeurope.api.cognitive.microsoft.com/vision/v1.0

It would be nice if you could enter the endpoint just like you do with the keys.

Even I set the endpoint (e.g. eastasia) in the main window, the pages still use the default (or hard-coded westcentralus). This will cause client throws exception.
I have local fix for it, however, not sure how to create a PR.

From @SaqibS on December 19, 2015 16:54

I have an Azure service which makes use of multiple Project Oxford APIs, and overnight calls to each of the services started failing.

I looked through the logs, and found that the client libraries for both Vision and Face were throwing a System.Exception, with message: "Transport error".

Eventually, I found that invoking the APIs using rest directly, I got a useful message back, saying that the keys had expired. Why this happened is a separate issue, along with why I didn't get any emails to say that the keys were going to expire (they still show as active on the website). But that's all separate - this bug relates to the fact that the client libraries shouldn't just throw a generic Exception with such a vague message. The message returned by the rest API should be wrapped in the client-specific exception.

I'm not 100% sure I'm in the right place to report this, but: I'm testing the Demo handwriting recognition ( https://azure.microsoft.com/en-ca/services/cognitive-services/computer-vision/#handwriting ) on some vintage postcards.

I've found that I can submit an image and get no results, or nonsense results back. But if I submit the negative version of the exact same image then the results are perfect.

Original image: https://1drv.ms/u/s!As3ZytCDCPbLkIJdz5P2TCj7nRijHA
Color inverted image: https://1drv.ms/u/s!As3ZytCDCPbLkIJcytVrtB0OrmDHTg

(In this case, the text is typed but I've been using the handwriting demo because they are often hand printed.)

I thought this might provide an avenue for improvement, i.e., if the service also processed the negative of the submission and compared confidences.

I opened the solution VisionAPI-WPF-Samples, but the build failed:

It looks like WPF sample build fails. The Client UI library needed to build the sample is not part of the repo. The library needs to be added as part of the repo for the WPF sample to build.

No changes made to the code or anything, the default is throwing an exception.

From @snap608 on April 6, 2016 19:49

Since the VisionServiceClient (C#) have no timeout we should be able to pass a CancelationToken or set a timeout for all calls to the API via the VisionServiceClient.

PS: Because of the downtime today (6.apr 2016) our integration encountered a hang.

I have a requirement to identify machinery image like (Lathe, Miller, Shaping etc.). But Analyze Image API (https://api.projectoxford.ai/vision/v1.0/analyze) is not providing correct machinery name. Attached is the image of a Lathe Machine but it is providing [ { "name": "sky", "confidence": 0.985724687576294 }, { "name": "projector", "confidence": 0.1976199895143509 } ]

Also another image of "Shaping Machine" but Analyzer is providing "Miller" Machine. PFA

Is there any way to correct an incorrect tagged image?

hello every body..

i followed the steps written here

https://www.microsoft.com/cognitive-services/en-us/computer-vision-api/documentation/getstarted/getstartedvisionapiforwindows

i downloaded the codes zip from gethups

1- the folder Sample-console not found

2- i tryied the examole inside SAMPLE.WPF and when tring to start the c# project, alot of errors generated like this:

Error CS0234
The type or namespace name 'ProjectOxford' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
VisionAPI-WPF-Samples C:\Users\khadijah\Documents\Visual Studio 2015\ProjectOxford-ClientSDK-CognitiveServices_1606\Vision\Windows\Sample-WPF\AnalyzeInDomainPage.xaml.cs
43 Active

do you have any idea please ..

thanks in advanced.

The blobs no longer exist.

Not found.

Copying from the readme, "The Vision Client Library is here for archival purpose only. .NET users are asked to switch to the newer Microsoft.Azure.CognitiveServices.Vision.ComputerVision package, the source for which can be found here."

The github link to the source for the newer Computer Vision software is broken, and I cannot find updated samples.

Since #14 the sample app is failing to build.

This is temporary and will be fixed as soon as the newest NuGet package is published

MainPage.xaml contains a single element in side the root grid - sampleUtil:SampleScenarios - which is in a project that is not part of the solution or repo.

Copy does not build. Looking for SampleUserControlLibrary; which is not downloaded.

On the page https://azure.microsoft.com/en-us/services/cognitive-services/computer-vision, there is a section telling that Vision API is able to recognize landmarks, and an example regarding Colosseum is provided:

However, if I try to call the Vision API using an URL like the following one, with the same image in the body:

POST https://westcentralus.api.cognitive.microsoft.com/vision/v1.0/analyze?visualFeatures=Categories&language=en&subscription-key=<my_subscription_key>

I obtain this:

So, the categories are the same, but with no detail. Am I missing something in order to retrieve landmarks information?
