We propose an algorithm to solve a problem in image restoration which considers several different aspects of it, namely: irregular sampling, denoising, deconvolution, and zooming. Our algorithm is based on an extension of a previous image denoising algorithm proposed by A. Chambolle using total variation, combined with irregular to regular sampling algorithms proposed by H.G. Feichtinger, K. Gr...

In this paper an automatic system to integrate virtual objects into image sequences taken by a rotating and zooming camera is presented. In this case of camera motion the observed static scene can be represented as a 2D panoramic mosaic image, which is estimated from the image sequence. Virtual objects can be positioned easily in the mosaic image with standard image editing software. The modifi...

Small devices such as Palm and Pocket PC have gained much popularity with the advent of mobile technology and price affordability. Image browsers are among popular software applications on PDAs. The limitations introduced by these devices such as screen resolution, processing power and interaction make it harder for multimedia applications designed for larger displays to be as much usable on sm...

This paper discusses the representation and explanation of relationships between phenomena that are important in psychiatric contexts. After a general discussion of complexity in the philosophy of science, I distinguish zoomingout approaches from zooming-in approaches. Zooming-out has to do with seeing complex mental illnesses as abstract models for the purposes of both explanation and reductio...

Tools for computer-aided satellite image analysis require inter-activity, i.e. the capability to modify some parameters and see instantaneously the result of the processing, for eecient work. Due to the amount of data to process that interactivity can only be achieved by parallel ar-chitectures. In this paper, we show how a data-ow computer developed in our laboratory can be used to prototype t...

A new approach is presented to automatically build a dynamic and multi-resolution 360° panorama (DMP) from image sequences taken by a hand-held camera. A multiresolution representation is built for the more interesting areas by means of camera zooming. The dynamic objects in the scene can be detected and represented separately. The DMP construction method is fast, robust and automatic, achievin...

The Bayesian approach is most widely used to solve various problems in signal and image processing, such as denoising and deblurring, zooming, reconstruction. The reason is that it provides a coherent statistical framework to combine observed (noisy) data with prior information on the unknown signal or image. However, this paper exhibits a major contradiction since the MAP solutions substantial...

The dynamic nature of virtual display spaces can provide powerful tools for helping people comprehend phenomena that occur over widely disparate spatial scales. This paper presents the macroscope, an interactive technique for browsing very large spaces of displayed information at different scales. The macroscope takes as a point of departure the traditional 2D zoom and pan operations, but intro...

In mobile environments, the size of large raster images often exceeds the display area on small output devices. The rectangular FishEye-View as a Focus&Context technique can be used to provide an interactive view of the image without zooming and panning. This paper presents the application of JPEG2000 for the demand-driven transmission of image data optimized for this display technique. The pro...
