Teaser: Illustrations of Paint Mesh Cutting. The user paints the region of interest with a single brush (in blue) on a mesh surface and then obtains the cutting part (in orange). Our system can provide the user instant feedback of the cutting results during mouse dragging (from left to right).Note that we only show 3 snapshots of the continuously sampled point interaction here.
Abstract
We present a novel
progressive painting-based mesh cut out tool, called Paint Mesh Cutting,
for interactive mesh segmentation. Different from the previous user
interfaces, the user only needs to draw a single stroke on the
foreground region and then obtains the desired cutting part at an
interactive rate. Moreover, the user progressively paints the region of
interest using a brush and has the instant feedback on cutting results
as he/she drags the mouse. This is achieved by efficient local graph-cut
based optimizations based on the Gaussian mixture models (GMM) on the
shape diameter function (SDF) metric of the shape. We demonstrate a
number of various examples to illustrate the flexibility and
applicability of our system and present a user study that supports the
advantages of our user interface.
