Generated event frames exhibit ghosting

[DelinQu]

Hi,
Thanks for releasing this easy-to-use toolbox, it really helps me. However, when using the event generator to generate event frames, I observed the presence of ghosting in the generated frames. These ghosting artifacts have a shape that closely matches the shape of the first frame. I have checked various aspects such as image paths, sorting, and visualization, ruling out any issues in those areas. Hence, I have narrowed down the problem to the event generator itself.

The first frame (with a window size = 5 RGB frames):

The 25th frame:

This issue does not appear to be a mere coincidence, as I have examined the entire sequence of the video, and all frames exhibit the same ghosting artifacts. I am curious if anyone else has encountered a similar problem. Has anyone experienced this issue before? Any assistance or insights into resolving this problem would be greatly appreciated.
