Object preview not showing detected objects (Vision Builder 2013 and 2018)

[Istvan_Ori]

Hi,

I recently encountered a strange behavior on one of our inspection systems when trying to set an Detect Object step. Unfortunately the objects detected by the algorithm aren't being highlighted with the preview color. This only seems to happen when using color images, as Detect Objects works fine with grayscale images.

Did anyone encounter such issue in the past? Is there any solution for it?

I tried installing VBAI 2018 on the same PC (I was using VBAI 2013 beforehand), but the issue appears in this software as well.  

Thank you in advance.

NOt really Nice to know. 

BTW, how can I reproduce this issue in my system?

I don't have the solution but I would like to mention that I have the same behaviour on VBAI 2019. It does not work for color images, it is fine for gray scale.

On the same computer, VBAI 2020 shows the preview for both color images and gray scales, there is no problem.
