Variation Based Dense 3d Reconstruction: Application on Monocular Mini-laparoscopic Sequences

<P>IN HIS MASTER THESIS, SVEN PAINER DEVELOPS, IMPLEMENTS, AND EVALUATES A METHOD TO RECONSTRUCT THE LIVER SURFACE FROM MONOCULAR MINI-LAPAROSCOPIC SEQUENCES. THE PRINCIPAL FOCUS OF HIS RESEARCH IS TO CREATE A BASIS FOR HELPING CLINICIANS TO WRITE REPORTS WITH QUANTITATIVE DESCRIPTIONS OF THE LIVER SURFACE. A STRUCTURE FROM MOTION APPROACH IS PERFORMED TO DO A SPARSE RECONSTRUCTION OF THE LIVER SURFACE AND SUBSEQUENTLY THIS INFORMATION IS USED IN A VARIATION BASED DENSE 3D RECONSTRUCTION. THE ALGORITHMS ARE FORMULATED IN A CAUSAL WAY, ENABLING THE IMPLEMENTATION TO BE RUN IN REAL-TIME ON AN ADEQUATE HARDWARE PLATFORM. THE RESULTS SHOW A SIGNIFICANT PERFORMANCE INCREASE AND PAVE THE WAY TO GIVE CLINICIANS A FEEDBACK DURING VIDEO CAPTURING TO IMPROVE THE QUALITY OF THE RECONSTRUCTION IN THE NEAR FUTURE.</P>
