ADR Issues with 6.4
ADR Issues with 6.4
I recently upgraded from 6.3 to 6.4 (6.3.0.4 to 6.4.0.10 of GDPicture.Net.dll). In 6.3 ADR used to work beautifully, but the same code compiled with 6.4 doesn't give the same confidence level. If I use the exact image as that of the template, ADRGetLastConfidence() method returns a confidence value of only 44%. With version 6.3, ADRGetLastConfidence() used to return 100%.
Is this an intentional change? Or is it a bug?

Hi,
Strange behavior. Could you try to update to GdPicture.NET 6.5 ?
If your problem persists, please attach your image used as template and give us some code you are using to retrieve confidence.
With best regards,
Loïc

Re: ADR Issues with 6.4
Hi,
I just upgraded to 6.5, but the problem persists. Please find the code used to create the template as well as to do ADR. I get confidence only between 40 and 60 for the exact same image (actually the exact same ImageID) only. It is not image specific. I tried with many imaged. The same code used to give confidence level of 100 with version 6.3.
I was using .Net 2.0. Tried the same code with .Net 3.5 as well. Same behaviour.
I would appreciate any help here.

Re: ADR Issues with 6.4
Hi Susanth,
I was unable to run your code "as is"
Please, create a standalone application or a simple code file without reference to other objects.
Also, I really need on of your image file for test.
Kind regards,
Loïc

Re: ADR Issues with 6.4
Hi again,
After other investigation we found a stupid bug in the ADR engine
The problem will be fixed in next minor release.
