Road curve attributes can be determined by using Geographic Information System (GIS) to used in road vehicle traffic safety and planning studies. This study involves analyzing the GIS-based estimation accuracy length, radius number of small horizontal curves on a two-lane rural forest road. The prediction success was investigated digitized raw generalized/simplified segments. Two different road...

The road is one of the transportation infrastructures that have a role as connector between regions, and also contributes to strengthening growth economy, society, tourism, culture region. Today, tourism activity in Indonesia growing rapidly, marked by increasing number tourist areas being built, which Arak-Arak natural area Bondowoso Regency, East Java. Located hilly with an altitude 345 meter...

We study geometric properties of horopters defined by the criterion of equality of angle. Our primary goal is to derive the precise geometry for anatomically correct horopters. When eyes fixate on points along a curve in the horizontal visual plane for which the vergence remains constant, this curve is the larger arc of a circle connecting the eyes' rotation centers. This isovergence circle is ...

Abstract-Consider the motion of a curve in the plane under its mean curvature. It is a very interesting problem to investigate what happens when there are intersection points on the curve at which the mean curvature is singular. In this paper, we study this issue numerically by solving the Allen-Cahn equation and the nonlocal evolution equation with Kac potential. The Allen-Cahn equation is dis...

The visual systems in primates are organized around orientation with a rich set of long-range horizontal connections. We abstract this from a differential-geometric perspective, and introduce the covariant derivative of frame fields as a general framework for early vision. This paper overviews our research showing how curve detection, texture, shading, color (hue), and stereo can be unified wit...

This paper gives a new inpainting model based on curve and horizontal line evolution. By connecting the level lines that reach the edges and let the connected lines have minimum curvature, the model can finish the task successfully. What’s more, the algorithm has no request on the topology of the inpainting area and can deal with all areas simultaneously.

A class of inequality measures that is a natural companion to the popular Lorenz curve is the class of measures that are linear in incomes. These measures, which include the Gini and S-Gini coefficients, can be interpreted as ethical means of relative deprivation feelings. Their change through the tax and benefit system can be decomposed simply as a sum of progressivity indices for individual t...
