introduction: having a desirable image in a market can be considered as an asset for an organization. therefore, using proper approaches, managers of such organizations must monitor and manage the image of their organizations in order to achieve their organizational goals and their customer’s satisfaction. as an important sector of every society, managers of hospitals also must try their best t...

one of the problems in the ground-based circular synthetic aperture radar is the dependence of the azimuth resolution to the antenna rotation radius and operational limitation of increasing it. to enhance the image quality in azimuth, model-based image formation through three methods: matched filter, inverse filter and optimum filter is suggested and analyzed. for the purpose of comparison, thr...

In 1990, one of us (Jackson) offered a hypothesis as an attempt to explain simultaneously all observations regarding the Shroud image (Ref 1). This hypothesis was ventured only after a systematic study of alternatives had failed to account for various image characteristics (Ref 2) and, though unconventional, this hypothesis makes a variety of testable predictions that are a-priori falsifiable b...

2014 The fiftieth anniversary of the publication of the first book on Fourier Optics, by P.-M. Duffieux, is recalled and the roles of the Fourier and many related transforms in image formation and image processing are recapitulated. Microsc. Microanal. Microstruct. 8 (1997) FEBRUARY 1997, PAGE 77

It is highly desirable that an imaging system has a single effective viewpoint. Central catadioptric systems are imaging systems that use mirrors to enhance the field of view while keeping a unique center of projection. A general model for central catadioptric image formation has already been established. The present paper exploits this model to study the catadioptric projection of lines. The e...

This article proposes a novel approach on how to rectify the photo image of the bound document. The surface of the document is modeled by a cylindrical surface. By the geometry of camera image formation, the equations using the cue of directrixes to map the points on the surface in the 3-D scene to the points on the image plane are achieved. Baselines of the horizontal text line are extracted a...

the paper tries to investigate the question whether photography could be considered as a source of knowledge since the medium has expanded our knowledge about the world, enriching our visual unconscious as benjamin puts it. highlighting the objective, mechanical formation of photographic image -not being shared by other forms of visual representation including painting and drawing-anumber of ph...
