 When you start processing a new data set, it can take some trial and error to figure out the set of image processing parameters that produce the best results. It is recommended that you start by tracking the bones (individually) in a single frame, trying different parameter values until the optimization algorithm can lock onto the correct pose for each bone. Then try solving a few adjacent frames to see if the same parameter values work on those. When you start processing a new data set, it can take some trial and error to figure out the set of image processing parameters that produce the best results.

 +===== Image Metrics =====

 +X4D can use one of two different image metrics to compare the X-ray and DRR images during object tracking:
 +  - [[other:dsx:x4d:pixel_difference|Pixel Difference]]
 +  - [[other:dsx:x4d:conditional_entropy|Conditional Entropy]]
