As a two-dimensional formal method, graph grammar is widely used in defining various visual programming languages. This paper presents a new graph grammar formalism called coordinate graph grammar (CGG). CGG is extended from the edge based graph grammar ...

This paper presents a shape grammar interpreter (SGI) with enhanced features. The shape grammar interpreter is able to automatically generate geometric products according to a given set of primitive shapes and rules applied to shapes. Several new ...

The powerful double-cut-and-join (DCJ) operation, introduced by Yancopoulos et al. [18], supports all classical genome rearrangement operations. This allows minimum edit distance to be computed by modeling all possible classical rearrangement ...

A computational environment for measuring heart rate from facial video is introduced. Developed with simplification in mind, the method consists of two general stages. First, the estimation of an unidimensional signal from a video streaming and, second, ...

Visual saliency detection aims at finding regions of interest which contain relevant information in images. In the last years, several saliency methods have been proposed, however, it is still a challenging task in visualization, graphics and computer ...

Macular Dystrophy is a rare, genetic eye disorder, which affects the retina. For example, Stargardt Disease (STGD) is a juvenile form of retina dystrophy that can result in loss of central vision, adversely affecting patients' daily activities. Often to ...

We consider several variants of the map-matching problem, which seeks to find a path Q in graph G that has the smallest distance to a given trajectory P (which is likely not to be exactly on the graph). In a typical application setting, P models a noisy ...

Computing Fréchet distance between two curves takes roughly quadratic time. The only strongly subquadratic time algorithm has been proposed in [7] for c-packed curves. In this paper, we show that for curves with long edges the Fréchet distance ...

We present an improved solution for the line facility location problem in a planar weighted subdivision. Our solution makes use of a key observation that improves on some theoretical bounds, and can be much faster in practice when compared to the ...

Immersive virtual reality systems often strive to support realistic physical interaction through direct hand control, but it is not often possible to configure the physical environment to exactly match the virtual environment. We study methods that ...

Head tracking is commonly used in virtual reality applications to allow users to naturally view 3D content using physical head movement, but many applications also support joystick control to allow additional turning. Joystick control is convenient for ...

Understanding complex concepts is known to be difficult and tedious. This complexity is very often due to lack of visual representation of abstract concepts, that cannot be easily observed. Representing these ideas in a visual Virtual Environment (VE) ...

The methods commonly used for people to converse despite a large geographical distance are either text messaging or video conference. A more immersive communication method which is similar to in-person conversation is more desirable. The closest form is ...

Multiple Sclerosis (MS) and Non-Specific White Matter (NSWM) lesion classification is a traditional problem in neurology. In this paper, we propose a machine learning method to predict MS/NSWM lesion types based on segmented 3D lesion models from ...

As more industries adopt the use of robots to increase productivity, there is an increased need for effective human-robot interaction training, especially in the case of heavy and high precision robots. This implies the need for easy assessment methods ...
