问题
I am working on identifying a face against set of faces in database using MS Cognitive Services - Face API.
If the input face is a side face then it throws,
The length of faceids is not in a valid range.
error.
Is it possible to compare a side face with front one using Face - API?
Thanks.
Note: There is a question on EmguCV(Right side Face detection with EmguCv) for the same but I am using MS Cognitive Services Face API.

Saravanan,
You may have already figured this out, but I hit a similar issue with calling the Face Group API:
GroupResult x = await faceServiceClient.GroupAsync(values);
When "values" in this example only contained one FaceID I got this error. In my case it was a mistake on my part, as it is impossible to group only one face. The error message was a bit cryptic, though, and it took me a while to figure it out. This may help someone else in the future.
