Time interpolation of angiograms toward stereoscopic display and reconstruction.
In the case of non simultaneous acquisitions of stereoscopic images, an object motion biases the 3D visualisation or reconstruction. We propose a method in order to find the interpolated image between two successive frames. It supposes that the motion locally corresponds to a translation. It works in the frequential domain and uses the phase information of the DFT. A special analysis of the phase component is made and allows to find the true interpolated phase. The application to stereoscopic angiographies illustrates the method and gives good results.
