Abstract: This chapter investigates the issue of the role of the computer,in musical analysis. Starting with a survey of the main approaches in computer analysis, we focus on the particular problem of Jazz chord sequences harmonic analysis. We propose a theory of chord sequence analysis, based on an explicit conceptual hierarchy of analysis objects. We discuss the implementation,of the theory

In light of contemporary developments that covered all fields, the companies struggle to acquire a broad base in consumers for the products offered in the global markets. They depend on the tremendous technological development that contributed to the convergence of the nations and societies. And the designers sought to achieve the universal design that obtains a widespread among broad societal levels and segments, according to its ease of perception from all people with different abilities.
The expansion of the application of the universal design includes the buildings' interior design to facilitate the interaction of individuals with the internal elements and to percept its details quickly. Therefore, the need came to define the extent to which the universal design principles can be achieved in the interior design spaces. And if it could deal with the variant human capabilities and whether its application in the buildings' interior may conflict with the fulfillment of different human needs. This research aims to clarify if it can provide the principles of the universal design that may contribute to achieving human comfort, psychologically and physically, in interior spaces, and that is through analytical and interpretative studies.

Research in learning algorithms and sensor hardware has led to rapid advances in artificial systems over the past decade. However, their performance continues to fall short of the efficiency and versatility of human behavior. In many ways, a deeper understanding of how human perceptual systems process and act upon physical sensory information can contribute to the development of better artificial systems. In the presented research, we highlight how the latest tools in computer vision, computer graphics, and virtual reality technology can be used to systematically understand the factors that determine how humans perform in realistic scenarios of complex task-solving.

This study is a first step in selecting an appropriate subword unit representation to synthesize highly intelligible 3D talking faces. Consonant confusions were obtained with optic features from a 320-sentence database, spoken by a male talker, using Gaussian mixture models and maximum a posteriori classification methods. The results were compared to consonant confusions obtained from visual-only human perception tests of non-sense CV syllables spoken by the same talker. At the phoneme level, machine classification results for the continuous speech database had worse performance than human perception with isolated syllables. However, the number of distinguishable consonant clusters by machine is equal to that by humans. To model the optic feature for continuous visual speech synthesis, the results suggest that for most consonants, modeling optic feature in phoneme level is more appropriate than modeling in phoneme clusters determined from visual-only human perception tests. For some...

The superficial appearance and color of food are the first parameters of quality evaluated by consumers, and are thus critical factors for acceptance of the food item by the consumer. Although there are different color spaces, the most used of these in the measuring of color in food is the L*a*b* color space due to the uniform distribution of colors, and because it is very close to human perception of color. In order to carry out a digital image analysis in food, it is necessary to know the color measure of each pixel on the surface of the food item. However, there are at present no commercial L*a*b* color measures in pixels available because the existing commercial colorimeters generally measure small, non-representative areas of a few square centimeters. Given that RGB digital cameras obtain information in pixels, this article presents a computational solution that allows the obtaining of digital images in L*a*b* color units for each pixel of the digital RGB image. This investigat...

A second faint image of the face of the Turin Shroud has been discovered in 2004 and many scientists in the world confirmed the discovery, but a recent paper has questioned in a debatable way its presence. With a perhaps too high degree of certainty it explained those patterns with pareidolia and Gestalt effects of the human perception, supporting its conclusion on the basis of illusory images perhaps built on purposes and on numerical results also derived from spatial crosscorrelation used in a not proper way. This paper both discusses these results showing why the image processing used in that paper seems not proper to sustain its thesis and presents additional image processing for pattern recognition.

‘Virtual globe’ software systems such as Google Earth are growing rapidly in popularity as a way to visualise and share 3D environmental data. Scientists and environmental professionals, many of whom are new to 3D modeling and visual communications, are beginning routinely to use such techniques in their work. While the appeal of these techniques is evident, with unprecedented opportunities for public access to data and collaborative engagement over the web, are there nonetheless risks in their widespread usage when applied in areas of the public interest such as planning and policy-making?This paper argues that the Google Earth phenomenon, which features realistic imagery of places, cannot be dealt with only as a question of spatial data and geographic information science. The virtual globe type of visualisation crosses several key thresholds in communicating scientific and environmental information, taking it well beyond the realm of conventional spatial data and geographic information science, and engaging more complex dimensions of human perception and aesthetic preference. The realism, perspective views, and social meanings of the landscape visualisations embedded in virtual globes invoke not only cognition but also emotional and intuitive responses, with associated issues of uncertainty, credibility, and bias in interpreting the imagery. This paper considers the types of risks as well as benefits that may exist with participatory uses of virtual globes by experts and lay-people. It is illustrated with early examples from practice and relevant themes from the literature in landscape visualisation and related disciplines such as environmental psychology and landscape planning. Existing frameworks and principles for the appropriate use of environmental visualisation methods are applied to the special case of widely accessible, realistic 3D and 4D visualisation systems such as Google Earth, in the context of public awareness-building and agency decision-making on environmental issues. Relevant principles are suggested which lend themselves to much-needed evaluation of risks and benefits of virtual globe systems. Possible approaches for balancing these benefits and risks include codes of ethics, software design, and metadata templates.

This research paper’s main objective is to present the current status of the residential Built settlement in the rural areas of Chettinard region in Tamil Nadu, a state rich in heritage, religious and cultural aspects in India. The research paper also correlates to the traces of the human life (socio-cultural and economic) and communities’ perception towards built heritage in Rural areas. For this purpose, the studies have been conducted on two of its villages which have been recommended as heritage village by the state government in UNESCO’s tentative list. In this study, the survey research is used as a study tool which proved to be a viable method for – First, testing the relevance and public reaction and perception to the conceptual models and theories of sustainable built environment, Secondly , providing relevant empirical and quantitative data documenting the heritage architecture and its effects on the human understanding and community perception. The paper also uses GIS as a software tool for a better understanding and cataloguing of the built heritage in a holistic manner

Setbacks for wind turbines have been established in many jurisdictions to address potential health concerns associated with audible noise. However, in recent years, it has been suggested that infrasound (IS) and low-frequency noise (LFN) could be responsible for the onset of adverse health effects self-reported by some individuals living in proximity to wind turbines, even when audible noise limits are met. The purpose of this paper was to investigate whether current audible noise-based guidelines for wind turbines account for the protection of human health, given the levels of IS and LFN typically produced by wind turbines. New field measurements of indoor IS and outdoor LFN at locations between 400 and 900 m from the nearest turbine, which were previously underrepresented in the scientific literature, are reported and put into context with existing published works. Our analysis showed that indoor IS levels were below auditory threshold levels while LFN levels at distances >500 ...

Due to the important role of cities for regional, national, and international economic development and the concurrent degradation of the urban environmental quality under rapid urbanization, a systematic diagnosis of urban ecosystem health for sustainable ecological management is urgently needed. This paper reviews the related research on urban ecosystem health assessment, beginning from the inception of urban ecosystem health concerns propelled by the development needs of urban ecosystems and the advances in ecosystem health research. Concepts, standards, indicators, models, and case studies are introduced and discussed. Urban ecosystem health considers the integration of ecological, economic, social and human health factors, and as such it is a value-driven concept which is strongly influenced by human perceptions. There is not an absolute urban ecosystem standard because of the uncertainty caused by the changing human needs, targets, and expectation of urban ecosystem over time; ...

Why do we have colour? What use is it to us? Some of the obvious answers are that we see colour so that we can recognise objects, spot objects more quickly, tell when fruit is ripe or rotten. These reasons make a lot of sense, but are there others? In this paper, we explore the things that colour makes easier for computational vision systems. In particular, we examine the role of colour in understanding specularities, processing interreflections, identifiying metals from plastics and wet surfaces from dry ones, choosing foveation points, disambiguating stereo matches, discriminating textures and identifying objects. Of course, what is easier for a computational vision system is not necessarily the same for the human visual system but it can perhaps help us create some hypotheses about the role of colour in human perception. We also consider the role of colour constancy in terms of whether or not it is required for colour to be useful to a computer vision system.
