Raster maps are widely available in the everyday life, and can
contain a huge amount of information of any kind using labels,
pictograms, or color code e.g. But due to those overlapping features,
it’s not an easy task to extract roads from those maps. Many methods
use user input to achieve this goal.
In this paper we focus on an automated method to extract roads by
using color segmentation and linear features detection to search for
seed points having a high probability to belong to roads. Those seeds
are then expanded before choosing to keep or to discard the extracted
element.

　概要を見る

Three different kinds assumptions are often used for
representing the shape of a paper:rigid, foldable and
nonrigid. Nonrigid surface detection is intensively explored
as challenging topics which addresses two problems:
recovering the paper shape and estimating the
camera pose. The state-of-the-art researches try to
solve both problems robustly for real time purpose. We
propose an augmented reality application that use a
nonrigid detection method to recover the shape of the
bendable paper using dots as keypoints and estimate
the camera pose simultaneously. Our approach recovers
the multi-planarity of the paper as the initial shape
and iteratively approximates the surface shape. The
multi-planarity is estimated by using the tracking by
descriptor update method that uses the correspondence
between captured and reference keypoints. We then optimize
the shape using the progressive finite newton optimization
method.
