    Matrix Determination of Reflectivity of Hidden Object via Indirect Photography

    Get PDF
    Indirect photography is a recently demonstrated technique which expands on the principles of dual photography and allows for the imaging of hidden objects. A camera and light source are collocated with neither having line-of-sight access to the hidden object. Light from the source, a laser, is reflected off a visible non-specular surface onto the hidden object, where it is reflected back to the initial non-specular surface and collected by the camera. This process may be repeated numerous times for various laser spot positions to yield slightly different camera images due to a variation in the illumination of the object. These images can then be used to construct an “indirect” image of the hidden object. This work provides an alternative method of processing the camera images by modeling this system as a set of transport and reflectance matrices. This approach reduces the required size of the visible scattering surface. Matrix formulation and those parameters shown in simulation to improve indirect image quality as measured by a modified MTF, including the method of matrix inversion, number and pattern of laser spots, are discussed

    Privacy as a Public Good

    Privacy is commonly studied as a private good: my personal data is mine to protect and control, and yours is yours. This conception of privacy misses an important component of the policy problem. An individual who is careless with data exposes not only extensive information about herself, but about others as well. The negative externalities imposed on nonconsenting outsiders by such carelessness can be productively studied in terms of welfare economics. If all relevant individuals maximize private benefit, and expect all other relevant individuals to do the same, neoclassical economic theory predicts that society will achieve a suboptimal level of privacy. This prediction holds even if all individuals cherish privacy with the same intensity. As the theoretical literature would have it, the struggle for privacy is destined to become a tragedy. But according to the experimental public-goods literature, there is hope. Like in real life, people in experiments cooperate in groups at rates well above those predicted by neoclassical theory. Groups can be aided in their struggle to produce public goods by institutions, such as communication, framing, or sanction. With these institutions, communities can manage public goods without heavy-handed government intervention. Legal scholarship has not fully engaged this problem in these terms. In this Article, we explain why privacy has aspects of a public good, and we draw lessons from both the theoretical and the empirical literature on public goods to inform the policy discourse on privacy

    Co-creation and Participation as a Means of Innovation in New Media: An Analysis of Creativity in the Photographic Field

    Get PDF
    This study endeavors to shed some light on the notion of co-creation in the global context of new media user participation and its relationship with innovation. First, the different discourses surrounding the notion of co-creation will be discussed, which are mainly addressed to industry-oriented projects. Alternatively, a nondirected case study focused on digital photography will be presented, enabling an analysis of co-creation through the lens of the theories of creativity. Consequently, through connecting creativity with our fieldwork, we suggest that the transformation of a cultural field by means of co-creation can lead to innovations that affect the entire field

    Data Analytics and Knowledge Integration Mechanisms: The Role of Social Interactions in Innovation Management

    Get PDF
    In a firm, which is viewed as a distributed knowledge system, the role of knowledge integration mechanisms is critical. In the context of data analytics, data mining and statistical analysis enables firms to generate knowledge; which, however, needs to be channeled to the end user of this knowledge. In this study, based on the social capital literature we argue that social interactions between IT and marketing functional unit members facilitate knowledge sharing in intraorganizational setting, which in turn results in improved innovative performance. The theoretical arguments are supported by empirical results collected via an online survey. Theoretical and practical contributions of the study are also discussed
