Xamarin Microsoft Oxford Vision problem with text recognize
I have a problem with text recognition from receipts using Microsoft Oxford Vision with Xamarin.Forms.
Here is a code:
private async void BtnTake_Clicked(object sender, EventArgs e)
{
try
{
var photo = await TakePic();
Image = ImageSource.FromStream(() => photo.GetStream());
var result = client.RecognizeTextAsync(photo.GetStream()).Result;
var words = from r in result.Regions
from l in r.Lines
from w in l.Words
select w.Text;
OutputText = string.Join(" ", words.ToArray());
await Navigation.PushAsync(new TextFromPhoto(OutputText, Image));
}
catch (Exception ex)
{
OutputText = "Ops! Something wrong!" + ex.ToString();
await Navigation.PushAsync(new TextFromPhoto(OutputText, Image));
}
}
private async Task<MediaFile> TakePic()
{
var file = await CrossMedia.Current.TakePhotoAsync(new StoreCameraMediaOptions
{
SaveToAlbum = true,
PhotoSize = PhotoSize.Medium
});
return file;
}
Code is perfectly working with normal text, like book photo page what i was took in application, but when i'm trying to use this to scan text from receipt program doesn't know what to do and on output we can see "513nlkm nlmnl l1mk 531" or something like that.
Photo when i have "normal" text:
Photo when i have receipt text:
Are there any proven ways to fix this?
