Innovative applications of associative morphological memories for image processing and pattern recognition.

Manuel Graña, Peter Sussner, Gerhard Ritter (2003)

Mathware and Soft Computing

Morphological Associative Memories have been proposed for some image denoising applications. They can be applied to other less restricted domains, like image retrieval and hyperspectral image unsupervised segmentation. In this paper we present these applications. In both cases the key idea is that Autoassociative Morphological Memories selective sensitivity to erosive and dilative noise can be applied to detect the morphological independence between patterns. Linear unmixing based on the sets of...

INSPIRE: Realizing the Dream of a Global Digital Library in High-Energy Physics

Holtkamp, Annette, Mele, Salvatore, Šimko, Tibor, Smith, Tim (2010)

Towards a Digital Mathematics Library. Paris, France, July 7-8th, 2010

High-Energy Physics (HEP) has a long tradition in pioneering infrastructures for scholarly communication, and four leading laboratories are now rolling-out the next-generation digital library for the field: INSPIRE. This is an evolution of the extraordinarily successful, 40-years old SPIRES database. Based on the Invenio software, INSPIRE already provides seamless access to almost 1 million records, which will be expanded to cover multimedia, data, software, wikis. Services offered include citation...

Instability of the eikonal equation and shape from shading

Ian Barnes, Kewei Zhang (2010)

ESAIM: Mathematical Modelling and Numerical Analysis

In the shape from shading problem of computer vision one attempts to recover the three-dimensional shape of an object or landscape from the shading on a single image. Under the assumptions that the surface is dusty, distant, and illuminated only from above, the problem reduces to that of solving the eikonal equation |Du|=f on a domain in ℝ 2 . Despite various existence and uniqueness theorems for smooth solutions, we show that this problem is unstable, which is catastrophic for general numerical algorithms. ...

Integrated Design of an Active Flow Control System Using a Time-Dependent Adjoint Method

E.J. Nielsen, W.T. Jones (2011)

Mathematical Modelling of Natural Phenomena

An exploratory study is performed to investigate the use of a time-dependent discrete adjoint methodology for design optimization of a high-lift wing configuration augmented with an active flow control system. The location and blowing parameters associated with a series of jet actuation orifices are used as design variables. In addition, a geometric parameterization scheme is developed to provide a compact set of design variables describing the wing...

Interactive 3D Visualization of Bézier Curves using Java Open Graphics Library (JOGL)

Vlachkova, Krassimira, Boikova, Marina (2011)

Serdica Journal of Computing

We present a new program tool for interactive 3D visualization of some fundamental algorithms for representation and manipulation of Bézier curves. The program tool has an option for demonstration of one of their most important applications - in graphic design for creating letters by means of cubic Bézier curves. We use Java applet and JOGL as our main visualization techniques. This choice ensures the platform independency of the created applet and contributes to the realistic 3D visualization....
