3-d geometry enhancement by contour optimization in turntable sequences
A method for the enhancement of geometry accuracy in shapefrom-shading frameworks is presented. For the particular case of turntable scenarios, an optimization scheme is presented that minimizes silhouette deviations which correspond to shape errors. Only three unknown parameters have to be optimized leading to a robust and relatively fast framework. In spite of the small number of parameters, experiments have shown that the silhouette error can be reduced by a factor of more than 10 even after an already quite accurate camera calibration step. The quality of an additional texture mapping can also be drastically improved making the proposed scheme applicable as a preprocessing step in many different 3-D multimedia applications.
