Stereo Matching with Reliable Disparity Propagation
Abstract—In this paper, we propose a novel propagationbased stereo matching algorithm. Starting from an initial disparity map, our algorithm selects highly reliable pixels and pr...

Improving Deformable Surface Meshes through Omni-Directional Displacements and MRFs
Abstract. Deformable surface models are often represented as triangular meshes in image segmentation applications. For a fast and easily regularized deformation onto the target obj...

Linguistic summarization of time series using a fuzzy quantifier driven aggregation
We propose new types of linguistic summaries of time-series data that extend those proposed in our previous papers. The proposed summaries of time series refer to the summaries of...

Guarding galleries and terrains
Let P be a polygon with n vertices. We say that two points of P see each other if the line segment connecting them lies inside (the closure of) P. In this paper we present efficie...

On Reconfiguring Radial Trees
A linkage is a collection of line segments, called bars, possibly joined at their ends, called joints. Straightening a tree linkage is a continuous motion of their bars from an ini...

Hough Transform for Region Extraction in Color Images
This article aims to propose a method to use the idea of Hough Transform (HT) implemented in grey scale images to color images for region extraction. A region in an image is seen ...

Line voronoi diagram based interpolation and application to digital terrain modelling
Local coordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the "neighbourliness" of data sites. In an earlier paper, we have ...

Fast Computation of Smallest Enclosing Circle with Center on a Query Line Segment
Here we propose an efficient algorithm for computing the smallest enclosing circle whose center is constrained to lie on a query line segment. Our algorithm preprocesses a given s...
