Abstract
A computer-implemented method for intensity projection includes providing volume data, determining an estimated threshold for determining a maximum/minimum intensity value in the volume data from temporal coherence and spatial coherence information, performing the second pass for determining an actual maximum/minimum value along the new ray, wherein the second pass uses the estimated threshold as an initial threshold, and updating the buffer with a new location value where the actual maximum/minimum value for the next frame was determined.
