We present here a real time filtering procedure, called S.Ti.F., which is able to make both soft and bone tissue clearly visible into a cephalometric radiography. Histogram based clustering allows separating the bone pixels from the other ones. Different gamma corrections are then applied to bone and soft tissue areas, in order to obtain a clear visualization of the local anatomical structures. Trials on a large dataset of images demonstrated the power of the proposed filter. The real time processing and the possibility to interactively modify the filter parameters make it a very useful tool for dentists and surgeons.

Abstract
We present here a real time filtering procedure, called S.Ti.F., which is able to make both soft and bone tissue clearly visible into a cephalometric radiography. Histogram based clustering allows separating the bone pixels from the other ones. Different gamma corrections are then applied to bone and soft tissue areas, in order to obtain a clear visualization of the local anatomical structures. Trials on a large dataset of images demonstrated the power of the proposed filter. The real time processing and the possibility to interactively modify the filter parameters make it a very useful tool for dentists and surgeons.
