A discussion on the interest of the study of diffractional image formation theory in a course of Fourier Optics is carried out We develope a general description of the partially coherent illumination case. Images of extended objects like the line and periodical structures are given for different values of the coherence parameter. The apparent transfer function is introduced as a quality criteri...

This paper describes an algorithm for the reconstruction of 3D medical objects from ultrasound images. Reconstruction is performed by ®ltering and interpolating the available data using an optimal Bayesian criterion. A Rayleigh model is adopted to describe the image formation process.

The advent of new and improved imaging devices has allowed an impressive increase in the accuracy and precision of MRI acquisitions. However, the volumetric nature of the image formation process implies an inherent uncertainty, known as the partial volume effect, which can be further affected by artifacts such as magnetic inhomogeneities and noise. These degradations seriously challenge the app...

The purpose of this paper is to investigate if it is possible to use estimation techniques to reduce the difference between predicted and actual RGB values. Images and spectral reflectances of two classes of objects were used: matte, 2D (Munsell chips and Macbeth chart) and natural, 3D objects (faces). In the prediction phase, a simple RGB model was evaluated which takes into account only the s...

This paper presents a novel tool for localizing people in multi-camera environment using calibrated cameras. Additionally, we will estimate the height of each person in the scene. Currently, the presented method uses the human body silhouettes as input, but it can be easily modified to process other widely used object (e.g. head, leg, body) detection results. In the first step we project all th...

We present an approach to recover scenes deteriorated by reeections oo a semi-reeecting medium. The approach is based on imaging through a polarizer at two diierent orientations. We analyze the image formation process taking into account changes in the reeection and polarization properties due to internal reeections within the medium. Reconstruction by inverting this process requires the estima...

The paper reviews the literature on destination branding, destination image and reasons for revisiting and recommending. The branding of destinations has gained popularity among city in recent years. The current study aims to develop and test a theoretical model of destination branding, which integrates the concepts of the branding and destination image. Specifically, the current study examines...

Recent advances in object recognition have emphasized the integration of intensity-derived features such as affine patches with associated geometric constraints leading to impressive performance in complex scenes. Over the four previous decades, the central paradigm of recognition was based on formal geometric object descriptions with a focus on the properties of such descriptions under perspec...

We introduce a network of networks (NoN) model to solve image regularization problems. The method is motivated by the fact that natural image formation involves both local processing and globally coordinated parallel processing. Both forms are readily implemented using an NoN architecture. The modeling is very powerful in that it achieves high-quality adaptive processing, and it reduces the com...

John Jackson has claimed that the only way all of the features observed on the Shroud of Turin could have been formed would involve the body becoming "mechanically transparent" concomitant with the appearance of a flux of vacuum-ultraviolet photons. The photons would produce the image as the cloth fell through the volume previously occupied by the body. This would explain the appearance of imag...
