In geometric modeling of curves and surfaces, the overall shape of an individual patch is intuitively governed by the placement of control points, and a patch may be finely tuned by altering the weights of the basis functions—large weights pull the patch towards the corresponding control points. The control points also have a global meaning as the patch lies within the convex hull of the contro...

Pollinating insect populations, essential for maintaining wild plant diversity and agricultural productivity, rely on (semi)natural habitats. An increasing human population is encroaching upon and deteriorating pollinator habitats. Thus the population persistence of pollinating insects and their associated ecosystem services may depend upon on man-made novel habitats; however, their importance ...

Although program repair is a tremendous aspect of software system, it can be extremely challenging. An Automated Program Repair (APR) technique has been proposed to solve this problem. Among them, template-based APR shows good performance. One the key properties for practical use its efficiency. However, because existing techniques mainly focus on performance improvement, they do not sufficient...

In this paper, first, I will give a brief concept about what the edge and corner is, and for what purpose of catching that information. Then I introduce several popular methods to detect edges and corners and give some experimental results. In early researches, usually the edge enhancement operators have been derived heuristically. We will see that an analytic approach to the design of these op...

Abstract Natural images, textures and photographs are likely to be impaired by stains.  As a result a substantial portion of the image remains blurred. However, a method called region completion is adopted to fill in the tainted part by using the information from the portion left unblemished by stains. A novel method to perform this operation is proposed in this paper. The three significant sta...
