GPS/INS Systems for compilation of digital large-scale orthophotos

2004

The paper describes the first results of a study, supported by an Italian research project “Integrated Inertial Positioning Systems in Aerial Photogrammetry” on the potential use of these techniques for production of digital large scale orthophotos. The study has been done with aerial photographs collected from two different flights executed in Sicily: the former, relating to the city of Palermo, at average scale of 1:9300; the latter, over the city of Catania, at average scale of 1:2000. For both flights the orthorectification was carried out by direct georeferencing methods and by traditional photogrammetric techniques, using ground control points surveyed by means GPS techniques and aeri…

Luigi Farrauto, 旅行者设计师 / Luigi Farrauto, travelling designer

2010

Luigi Farrauto成功地融合了自己生活中的两个方 面——专业的工作和激情的生活，这使他成为了一 位独一无二的平面设计师，而同时又是一个热情的 年轻人。他对旅行和学习的热情以及他对信息系统 设计和标志设计的热情相互渗透并互相补充，产生 了一种持续的交叉互补，这种交叉互补可以自然而 然地自生下去而不需要有意为之。旅行者的眼光是 犀利、敏锐而又仔细的，能够捕捉到一个领域中的 不同元素、不同图标和不同文字，这在设计帮助人 们自我定位的标志系统时十分有利。 Luigi Farrauto has been able to put together two aspects of his life, the professional and the passionate ones, merging them in a sole and unique specificity, which distinguishes him both as a graphic designer and as a young man. His passion for travel and study and for the design of systems of information and of signs, penetrate and feed each other, generating a continuous cross-reference which perpetuates itself without any apparent effort. The traveler’s gaze i…

The impact of the software’s choice on dynamic daylight simulations’ results: A comparison between Daysim and 3ds Max Design®

2015

Abstract Evaluating indoor daylight availability is extremely important in order to define the characteristics of an environment in terms of visual comfort and energy performances of lighting systems. The criticism of the static calculation approach based on Daylight Factor led to the development of the Climate Based Daylight Modeling (CBDM) one. Dynamic simulations are performed thanks to the use of specific software and the choice of a calculation tool or another could provide different output results. Therefore the aim of this paper is to compare results of dynamic daylight simulations carried out with two different software, Daysim and 3ds Max Design® and referred to a simple office loc…

An Intelligent Car Driver for safe Navigation with Fuzzy Obstacle Avoidance.

2009

In order to respond effectively to the environment uncertainties, autonomous vehicles are generally equipped with sensors. The proposed car guidance system is equipped with an intelligent controller, based on fuzzy logic, which calculates the speed and wheels orientation in order to follow a path while it is avoiding unknown obstacles. Better fluidity of driving are obtained using future-path, car dimension and car position prevision. Vehicle symmetries also speed-up and simplify the guidance system reducing the inputs and the rules numbers.

Multidirectional Scratch Detection and Restoration in Digitized Old Images

2010

Line scratches are common defects in old archived videos, but similar imperfections may occur in printed images, in most cases by reason of improper handling or inaccurate preservation of the support. Once an image is digitized, its defects become part of that image. Many state-of-the-art papers deal with long, thin, vertical lines in old movie frames, by exploiting both spatial and temporal information. In this paper we aim to face with a more challenging and general problem: the analysis of line scratches in still images, regardless of their orientation, color, and shape. We present a detection/restoration method to process this defect.

Unifying Textual and Visual Cues for Content-Based Image Retrieval on the World Wide Web

1999

A system is proposed that combines textual and visual statistics in a single index vector for content-based search of a WWW image database. Textual statistics are captured in vector form using latent semantic indexing based on text in the containing HTML document. Visual statistics are captured in vector form using color and orientation histograms. By using an integrated approach, it becomes possible to take advantage of possible statistical couplings between the content of the document (latent semantic content) and the contents of images (visual statistics). The combined approach allows improved performance in conducting content-based search. Search performance experiments are reported for…

Is There Anything New to Say About SIFT Matching?

2020

SIFT is a classical hand-crafted, histogram-based descriptor that has deeply influenced research on image matching for more than a decade. In this paper, a critical review of the aspects that affect SIFT matching performance is carried out, and novel descriptor design strategies are introduced and individually evaluated. These encompass quantization, binarization and hierarchical cascade filtering as means to reduce data storage and increase matching efficiency, with no significant loss of accuracy. An original contextual matching strategy based on a symmetrical variant of the usual nearest-neighbor ratio is discussed as well, that can increase the discriminative power of any descriptor. Th…

Combining textual and visual cues for content-based image retrieval on the World Wide Web

2002

A system is proposed that combines textual and visual statistics in a single index vector for content-based search of a WWW image database. Textual statistics are captured in vector form using latent semantic indexing (LSI) based on text in the containing HTML document. Visual statistics are captured in vector form using color and orientation histograms. By using an integrated approach, it becomes possible to take advantage of possible statistical couplings between the content of the document (latent semantic content) and the contents of images (visual statistics). The combined approach allows improved performance in conducting content-based search. Search performance experiments are report…

Tempo e ragione nella determinazione all’agire libero. Coordinate di orientamento

2013

The topic of the essay is the relationship between time and pure practical reason in the Kant’s Theory of the free determination of the will. We ask if the orientation of the free will to the moral law implies a specific orientation in time, in which the subject can get the sense of the absolute and urgent rational obbligation to the freedom. We analyse the dinamical aspect of the pure reason on the intermediete normative level of the maxims. We research in which kind of reference points in time are the conditions of possibility of the subversion of the empirical causality, of the turn of the subjective principles’ order, of the Revolution in Conduct of Thought. Furthermore temporal referen…
