I´m plannig to record transport of a rounded object along a line between
the images of a stack. I don´t expect to have a clear-cut contrast between
the object and the background. The aim is to get the speed (pixels/time)
of the movement along the line
I´ve thought of a handmade procedure:
1) draw a line
2) get line profile for each slice
3) put all the plot values in excel and calculate speed

However, the number of images is too high to make this by hand. Thus, I
need to automatize 2 and 3

Any help will be wellcome

Pedro
