This study aims to develop a novel imaging technique to improve the accuracy of the colposcolpic diagnosis of cervical cancer. An optical imaging system based on active stereo vision is built to measure the 3-D surface topology of cervix and track the motion of patient. The information of motion tracking are used to register the time-sequenced images of cervix recorded over the period of examin...

In this paper we present a new technique for tracking the movement of the myocardium using a statistical model derived from the motion fields in the hearts of several healthy volunteers. To build the statistical model we tracked the motion of the myocardium in 17 volunteers using a nonrigid registration technique based on free-form deformations and mapped the motion fields obtained into a commo...

Ultrasound is a favorable tool for intra-operative surgical guidance due to its fastimaging speed and non-invasive nature. However, deformations of the anatomy causedby breathing, heartbeat, and movement of the patient make it difficult to track thelocation of anatomical landmarks during intra-operative ultrasound-guided interven-tions. While elastic registration can be used to ...

Abstract The early exhumation history of the Tauern Window in European Eastern Alps and its surface expression is poorly dated quantified, partly because thermochronological provenance information are sparse from Upper Austrian Northern Alpine Foreland Basin. For first time, we combine a single‐grain double‐dating approach (Apatite Fission Track U‐Pb dating) with trace‐element geochemistry anal...

A computer vision technique is introduced to remove a moving foreground object in a video sequence for digital post-processing. Recently various digital special effects are employed in generating video production. This paper introduces one of the digital special effect techniques, moving object removal and background completion. To find a moving foreground object in a video sequence, we track b...

Using selective laser extraction technique combined with sensitive ion-counting mass spectrometry, we have analyzed the isotopic structure of fission noble gases in U-free La-Ce-Sr-Ca aluminous hydroxy phosphate associated with the 2 billion yr old Oklo natural nuclear reactor. In addition to elevated abundances of fission-produced Zr, Ce, and Sr, we discovered high (up to 0.03 cm(3) STP/g) con...
