When playing around with custom kernels in Vision Assistant 2013 I noticed that in the function "Filters" unter "Convolution - Custom", the size shown in the "Kernel Size" Control does not match the size displayed in the matrix view on the right of the control, as displayed in the attached picture #1.
Sizes larger that 5 grow to 17 instead of 7, 21 instead of 9, 25 instead of 11 and so on. When I hit OK and re-enter into the setup dialog, the Kernel size control shows "17" when I left it before with 7. I can then decrease the size from 17 to 7 and will finally get my 7x7 kernel.
Also, when using "Convolution Custom", and entering the first "customized" value, the focus in the filter selection list suddenly jumps to "Convolution - Highlight Details". If I decide that this shall not disturb me much and keep on entering the values, all is fine. Until I hit ok and then realize, I might have made a mistake, which makes me doubleclick the Filter Setup again. this results in a total change of the kernel I entered into the standard "Convolution - Highlight Details" with all those -1 s and the high positive number in the middle, see attached pictures #2 and #3.
Can anyone confirm this odd behavior?

Dear comrade,
I reproduced this issue like you described and it definitely looks like a Bug in the Vision Assistant 2013 Software.
So I will write a CAR which will be forwarded to R&D.
Thank you very much for your support

Dear comrade,
The CAR Nummer you can refer to is 452850.

Just for additional information:
When using VAS2011, almost the same behavior can be reproduced. Only advantage here is that when reentering the filter function the once entered kernel stays the same. However - the kernel size still changes to 21 instead of 7 and so on.
Thanks for the quick look into this and for filing the CAR.
Best regards
