I need to analyze a set of frames from a movie. I did that before by handling each individal frame image in a macro loop.
Because it is probably more efficient I now import the image sequence to form a stack. I am very surprised that the results are now different.
When I have a closer look at the individual slices, by “scrolling” through the stack with Next slice or the arrow keys, I see that in every slice I can also see a low intensity view on the next slice. When I do my analysis I notice that this “ghost” picture is also taken into account in my results.
How can I prevent this? Did I miss some setting ?
