Simplification Of Painting Images For Tactile Perception By Visually Impaired Persons

2018

The access to artworks by visually impaired people requires a simplified tactile representation of paintings. This paper presents the difficulties of direct transcription of artworks and the test results of simplification of the paintings done by Australian Aborigines which don't have purely visual elements such as shadows or perspective. The implemented methodology is bottom-up: it starts with tactile representation of basic elements relevant to the understanding of the whole painting, then their association into more complex concepts. The context of associations is explained through audio-description. The results of the tests with visually impaired persons are analyzed and explained.

Materiality and atmosphere. Two American beat artists painting Europe

2019

The article discusses how European painting heavily influenced two American Beat painters in the post war years. Post-war American painting was often concerned with breaking away from traditional iconography and style, but Jay DeFeo and Joan Brown chose to engage with European traditional painting. Both artists travelled to Europe early in their careers and both declare an intense interest in European painters, paintings, and architecture. In Brown’s case particularly the works of Goya, Velazquez, and Rembrandt become scrutinized and remodeled in her pasty abstract style. De Feo, on her hand, states a particular interest in how the European cities’ distinct colors, lights and textures inspi…

Donald Friedman's Interviews : Writers as Visual Artists

2018

With Volume 39, “Gestures and their Traces” INTERFACES, now an on-line journal, began its third iteration. In volume 40, we welcome Donald Friedman, novelist, essayist, and preeminently the author of The Writer’s Brush, Paintings, Drawings, and Sculpture by Writers, as a regular contributor to the journal. In the process of researching The Writer’s Brush, he video interviewed a number of contemporary writers; he is editing these tapes and these will begin a new feature of the journal. The fir...

The pictorial decoration of the church of Santa Maria La Porta in Geraci Siculo. Critical historical analysis of the canvases and frescoes. Iconographic readings, stylistic analysis and attributions

2020

Strontium isotopes in biogenic apatite, especially enamel, are widely employed to determine provenance and track migration in palaeontology and archaeology. Body tissues record the 87Sr/86Sr of bioavailable Sr of ingested food and water. To identify non-local individuals, knowledge of the 87Sr/86Sr of a non-migratory population is required. However, varying factors such as tissue turnover rates, feeding selectivity, Sr content, digestibility of food, and the ingestion of mineral dust can influence body tissue 87Sr/86Sr. To evaluate the Sr contribution of diet and water to mammalian hard tissues 87Sr/86Sr, controlled feeding studies are necessary. Here we present 87Sr/86Sr from controlled fe…

Ad laudem Divini nominis et honorem gloriosissimae Dei Genetricis et semper Virginis Mariae. L’abbazia di Santa Maria di Altofonte

2019

Inediti documenti fanno in parte riemergere l’antico splendore dell’abbazia di Santa Maria di Altofonte, fondata da Federico III e retta dal XV secolo da abati commendatari appartenenti a nobili famiglie, come Ascanio Colonna, Scipione Borghese e Francesco Maria Medici. Dell’esiguo patrimonio artistico rimasto fa parte la coppia di reliquiari di argentiere messinese del 1727 ascritta alla committenza dell’abate Bartolotta. New documents partly re-emerge the ancient splendour of the abbey of Santa Maria di Altofonte, founded by Frederick III and ruled since the 15th century by commendatory abbots belonging to noble families, such as Ascanio Colonna, Scipione Borghese and Francesco Maria Medi…

Post-mortem alteration of diet-related enamel surface textures through artificial biostratinomy: A tumbling experiment using mammal teeth

2019

In the fossil record, teeth are often all that remains of a fossil organism. Dental microwear texture analysis (DMTA) is a common proxy for diet using dental wear features at the μm-scale, enabling comparative and quantitative assessments of various feeding traits in extant and extinct species. In extinct species, original diet-related dental wear features may be overprinted by post-mortem alteration including fluvial transport. Here we experimentally investigate the effects of mechanical alteration on diet-related 3D enamel surface texture (3DST) patterns of different mammal teeth. Post canine teeth of Equus sp., Capreolus capreolus and Otomys sp. are tumbled in sediment-water suspensio…

A new 3-d approach to determine functional morphology of cercopithecoid molars.

2005

Summary Functional relationships between diet and tooth morphology form an integral part of primatological and paleontological research. Previously, mostly two-dimensional parameters have been used to compare and interpret the complex crown morphology of cercopithecine and colobine molars. However, as teeth are three-dimensional objects, any dimensional reduction in describing their morphology must result in loss of information. In the current study we use a high resolution optical topometric system to record crown morphology in different wear stages in order to extract three-dimensional (3-d) parameters from virtual 3-d models. Structural parameters such as relief index, occlusal surface a…

Review of Advanced Acoustical Imaging Techniques for Nondestructive Evaluation of Art Objects

2006

Proper preventative diagnosis of different art objects, including wooden, bronze and marble sculptures, frescoes, and paintings (on canvas, wood, metal, and glass), is very important for conservation purposes. Various advanced ultrasonic imaging methods for analysis and assessment of art objects can bring about drastic changes in the regular evaluation and inventory carried out by museums and can bring advanced, powerful, and new techniques for objective assessment of physical conditions of museum resplendence. Using these methods, it will be possible to plan ad hoc repair works on art objects, and, as a result, we will preserve our heritage. The goal of this review is to introduce recent a…

Wooden panel paintings investigation: An air-coupled ultrasonic imaging approach

2007

In this paper, a method for the study of wooden panel paintings using air-coupled acoustical imaging is presented. In order to evaluate the advantages of the technique, several samples were made to mimic panel paintings along with their typical defects. These specimens were tested by means of both single-sided and through-transmission techniques using planar transducers. Image data were processed by means of a two-dimensional (2-D)-fast Fourier transform-based algorithm to increase the S/N ratio and 2-D representations (C-scans) were generated. The simulated defects were imaged using both configurations. Investigations were undertaken on four antique paintings from a private collection. The…
