             abstract = "In direct volume rendering, the use of transfer functions allows 
                         the visualization of specific parts of the volume, revealing 
                         significant structures such as boundaries between different 
                         materials. To interactively specify an adequate transfer function 
                         is a very challenging and time-consuming task. Besides, a user can 
                         settle with a transfer function that does not reveal the overall 
                         structure inside the volume. Hence, the importance of generating 
                         adequate transfer functions automatically. Since Kindlmann and 
                         Durkin's seminal work on the semi-automatic generation of transfer 
                         functions, many research works have been conducted attempting to 
                         improve their proposal. Despite some fine resulting 
                         visualizations, many of these works aimed to diminish the problem 
                         of boundary overlaps, in the data domain, by using two-dimensional 
                         transfer functions, thus decreasing the focus on the automatic 
                         generation and leaving to the user, again, the task to manually 
                         isolate isosurfaces. Moreover, fine-tuning two-dimensional 
                         transfer functions is less intuitive than adjusting 
                         one-dimensional ones. This paper redirects Kindlmann and Durkin's 
                         concepts of boundary characterization and proposes a new method to 
                         automatically generate one-dimensional transfer functions, more 
                         robust to boundary overlaps. This work also suggests a rendering 
                         filter to isolate detected isosurfaces in the visualization.",
