I did 'image variance' for a list of images but the region of interest shows black line (see picture 1) instead of white as in picture 2. What seems to be the problem? does it need to increase the resolution or high pass filtering?

You have a series of images that all happen to be bright in certain areas. Because they are all bright there, the variance between them is low. When you display the variance, low variance would show up dark.
Variance images highlight areas that differ a lot between images, not areas that are similar.
