Hi I am trying to find all positions of codebook entries relative to the object center and stocked with it for many days. Like the following image:

The steps that I have done till now is extracting keypoints and building the codebook by kmeans clustering (creating visual vocabularies) in python, I do not know to find the center of each visual vocabulary and then calculate the position from the center. Could you please help with this?

  • you cannot do this, from the visual words (BOW) data alone. (there is no position data retained there)
  • please show the code, you have, so far
