Volume visualization based on the intensity and SUSAN transfer function spaces
A novel 2D IS transfer function space for distinguishing different materials have been proposed. Boundary of different materials exhibits as a trapezoid shape in the proposed space. Boundary information in the IS space is much better brought out in comparison to the IGM space. The IS space provides much more intuitive suggestions than the IGM space in order that transfer functions can be more easily designed. The proposed approach can be used to explore various medical volume data.
