Finger and hand detection for multi-touch interfaces based on maximally stable extremal regions. August , Multiresolution data representations are crucial for viewing large volumetric datasets interactively.

Ideally, a subset is chosen such that the error made when visualizing the subset compared to a visualization of the full data set is smaller than that of any other subset of the same size. For real-time applications it is computationally too expensive to calculate the exact error during runtime. Futher, computing error in a pre-processing step is usually not practical due to a large number of possible different configurations each requiring its own error computation.

For example, when coupling a multiresolution representation with a direct volume rendering technique, screen-space error depends on the transfer function and viewing direction, making impossible its pre-computation.
