Citation Count: 0

In this article, we examine the reconstruction of seventeenth century BC fragmented wall paintings, excavated at Akrotiri, Santorini, Greece. We use a previously presented algorithm for obtaining potential fragment matches based on the shape of the fragments. We then extract additional information from the fragments’ images in order to drastically ...
Keywords: 2D object reconstruction, Thematic content, Chromatic (color) content

In this paper, a general methodology is introduced for the determination of potential prototype curves used for the drawing of prehistoric wall paintings. The approach includes 1) preprocessing of the wall-paintings contours to properly partition them, according to their curvature, 2) choice of prototype curves families, 3) analysis and optimization ...
Keywords: Rotation and translation invariant curve fitting, pattern recognition in paintings, optimization in differentiable manifolds, geometric guides in prehistoric wall paintings, minimal parameters set for curve description, fitting prototype curves to drawn borders.

In this article, an integrated conjecture about the method of drawing of monumental prehistoric wall-paintings is presented and supported. Specifically, the article deals with paintings that initially decorated the internal walls of the highest floor of a building, called “Xeste 3”, at Akrotiri of the Greek island of Thera circa. ...
Keywords: Finding the method of drawing of paintings, prototypes determination in paintings, curve fitting, prehistoric paintings and geometry

A novel methodology is introduced here that exploits 2D images of arbitrary elastic body deformation instances so as to quantify mechanoelastic characteristics that are deformation invariant. Determination of such characteristics allows for developing methods offering an image of the undeformed body. General assumptions about the mechanoelastic properties of the bodies ...

In this paper an automated information system is presented, that classifies scripts to corresponding writers using graphology. The methodology is based on the idea of creating a representative of each alphabet symbol in each script via proper fitting of all realizations of the specific symbol in it. The decision for ...

This paper introduces a novel methodology for the classification of ancient Greek inscriptions according to the writer who carved them. Inscription writer identification is crucial for dating the written content, which in turn is of fundamental importance in the sciences of history and archaeology. To achieve this, we first compute ...

In this paper, a new decisively important factor in both the perceptual and the automated piano-guitar identification process is introduced. This factor is determined by the nontonal spectral content of a note, while it is, in practice, totally independent of the note spectrum tonal part. This conclusion and all related ...

In this paper, a methodology of general applicability is presented for answering the question if an artist used a number of archetypes to draw a painting or if he drew it freehand. In fact, the contour line parts of the drawn objects that potentially correspond to archetypes are initially spotted. ...

In this paper, an original general methodology is introduced to establish whether a handmade shape corresponds to a given geometrical prototype. Using this methodology, one can decide if an artist had the intention of drawing a specific mathematical prototype or not. This analysis is applied to the 1650 B.C. wall ...

Hands free operation is a standard feature of many fixed and mobile telephone sets. In hands free telephony, echoes appear at the far end, because of the open-air acoustic path between the loudspeaker and microphone at the near end. This paper presents an efficient realization of an Acoustic Echo Cancellation ...

A new methodology is presented for the automated recognition-identification of musical recordings that have suffered from a high degree of playing speed and frequency band distortion. The procedure of recognition is essentially based on the comparison between an unknown musical recording and a set of model ones, according to some ...

The exact and actual cause of the failure of the fast-Kalman algorithm due to the generation and propagation of finite-precision or quantization error is presented. It is demonstrated that out of all the formulas that constitute this fast Recursive Least Squares (RLS) scheme only three generate an amount of finite-precision ...
