Who's better at spotting? A comparison between aerial photography and observer-based methods to monitor floating marine litter and marine mega-fauna.

2020

Pollution by marine litter is raising major concerns due to its potential impact on marine biodiversity and, above all, on endangered mega-fauna species, such as cetaceans and sea turtles. The density and distribution of marine litter and mega-fauna have been traditionally monitored through observer-based methods, yet the advent of new technologies has introduced aerial photography as an alternative monitoring method. However, to integrate results produced by different monitoring techniques and consider the photographic method a viable alternative, this ‘new’ methodology must be validated. This study aims to compare observations obtained from the concurrent application of observer-based and…

Image Processing Chain For Digital Still Cameras Based On The Simpil Architecture

2005

The new generation of wireless devices herald the development of products for integrated portable image and video communication requiring to image and video applications high computing performance. Portable MultiMedia Supercomputers (PMMS), a new class of architectures, allow to combine high computational performance, needed by multimedia applications, and a big energy efficiency, needed by portable devices. Among PMMS, the SIMPil (SIMD processor pixel) architecture satisfies the above requirements, especially with video and digital images processing tasks. In this paper we, exploit the SIMPil computation and throughput efficiency to implement the whole image processing chain of a digital s…

A retinal snap shot may indicate individual risk for cardiovascular disease — The MIPH Eye&Health Study

2014

Examination of retinal vasculature can be used to non-invasively quantify changes within the microvasculature of the human body and might be a predictor of cardiovascular disease. This study evaluates associations of the structure of the retinal vasculature with established risk factors for cardiovascular disease.A cross-sectional study was performed in a working age population. Several systemic cardiovascular parameters were analyzed and PROCAM- and SCORE-risk estimates were calculated. A quantitative ophthalmological examination including digital fundus imaging has taken place. Central retinal arterial/venous equivalents (CRAE/CRVE) and arterio-venous ratio (AVR) were analyzed using valid…

Real-time acquisition of complex optical fields by binary amplitude modulation

2017

We describe, through simulations and experiments, a real-time wavefront acquisition technique using random binary amplitude masks and an iterative phase retrieval algorithm based on the Fresnel propagator. By using a digital micromirror device, it is possible to recover an unknown complex object by illuminating with this set of masks and simultaneously recording the resulting intensity patterns with a high-speed camera, making this technique suitable for dynamic applications.

Monoscopic Photogrammetry to investigate the buildings in the period of the Modernism in Salerno: the case study of Torquato Tasso High School

2022

The city of Salerno and the expansion that underwent in the 1920s in order to respond to the urban expansion following the demographic increase that occurred at the beginning of the century will be the topics discussed in this paper. Transformations that created a face to the city that, in its forms, although not linked to the most advanced avant-garde, represents a testimony of the new characteristics of the “modern” city. Within this evolutionary process of the province of Salerno there is the 1928 project of two engineers, Michele and his son Luigi De Angelis for the construction of the “Regio” School. In a first moment, several projects found in the archives refer mainly to the various …

Provini. Sull'enunciazione fotografica

2020

Before the shutter release subtracts a certain fragment of existence from its continuous becoming, producing that "that-has-been" that Barthes recognized as the very essence of photographic art, the world is in front of the photographer with all its complexity: the infinite things that populate it, the infinite points of view from which it is possible to look at them, the infinite moments that mark their existence. In front of the man with the camera, an infinite number of photographs unfolds, many of which, unfortunately, completely incapable of provoking that jolt you get when an image is really good. How is it possible to describe and analyze photographic production? To think about it, t…

An external gaze: the Sicilian cultural heritage photographed by foreign travellers during the second half of 19th century

Since its origin, photography was immediately involved in a lively debate about the relationships that this new technology could have with Art, its production, its exploitation and its conservation: even if it was perceived as a potential threat by someone, several voices emphasized the revolutionary influence that photography could have on the arts. It soon became clear that the new media could also be used for the documentation of events and cultural assets, and thus as a tool for knowledge and safeguarding of the artistic and monumental heritage. Photography will soon inherit the role of nature’s copyist traditionally attributed to engraving but, due to its technological limitations, its…

Interpretation of journalistic photographs as an instrument of visual literacy education

2016

Images are produced, used and distributed on an enormous scale. However, the skills of understanding, interpreting and using images as well as thinking and learning in terms of images are taken for granted, and thus, they are not sufficiently taught and developed, especially in higher education. The need for introducing visual literacy into the curriculum was identified in late 1960s, but no concrete guidelines have followed. This study proposes to apply interpretation of journalistic photographs as an instrument of visual literacy education. The main focus is on the image interpretation process and the kinds of meanings viewers apply to a photograph in the interpretation process. In each o…

Visti dagli altri: il patrimonio culturale siciliano fotografato dagli stranieri

La ricerca è incentrata sulla produzione riguardante il patrimonio monumentale, archeologico e storico-artistico siciliano realizzata da fotografi d'oltralpe, tra la seconda metà del XIX e gli inizi del XX secolo. Tramite l’analisi dell’evoluzione della rappresentazione del patrimonio siciliano da un punto di vista esterno, si vogliono individuare i principali soggetti di predilezione, le motivazioni alla base di queste scelte e l’influenza di questa iconografia nella costituzione dell’identità locale.

Social Lives of Monumental Walls: Hunting along the Upper Tigris

2021

On the left bank of the Tigris in northern Iraq, in an area today partially flooded by the Mosul Dam reservoir, lies an enigmatic monumental enclosure known in the literature as the “Tigris Wall.” Before its partial submersion under the waters of the modern lake, the large L-shaped embankment, about 4 × 4 km long, enclosed an area of ca. 1600 ha, overlooking the Tigris and its alluvial plain. By means of a holistic strategy that includes different levels of analysis (remote sensing, pedestrian and UAV photogrammetric surveys, excavation, and settlement pattern analysis), this paper addresses the structure, its context, and its environment. Relying on the results of this multi-disciplinary a…
