hello everyone,
i need help in one thing:
i analyze x-ray pictures with substance's internal damage. this damage
starts in one point and spread in to the elongated shape but the
bigginig is always more or less round plate. as i said it elongates in
time and getting wider in front part( i mean in this part which shows
direction of elongation). i use centre of mass operation to estimate the
direction of propagation. I'd like to ask you all to help me with this
testing. Does anyone knows plugin which can draw a vector on the base of
centre of mass of the particle? i mean start of the vector in the thiner
part of particle and end of the vector in the opposite end of particle
or in thecentre of mass? thanks in advance for any ideas
greeetings,
jarek
