This paper presents a unified approach to automatically build dynamic and multi-resolution 360° panoramic (DMP) representations from image sequences captured by hand-held cameras mainly undertaking rotation and zooming for natural scenes with moving targets. A simple (yet stable) rigid motion model and a closed-loop-based mosaicing algorithm are proposed to generate cylindrical mosaics automati...

A method for image analysis, representation and re-synthesis is introduced. Unlike other schemes it is not pixel based but rather represents a picture as vector data, from which an altered version of the original image can be rendered. Representing an image as vector data allows performing operations such as zooming, retouching or colourising, avoiding common problems associated with pixel imag...

This is an exploratory paper about combining logics, combining theories and combining structures. Typically when one applies logic to such areas as computer science, artificial intelligence or linguistics, one encounters hybrid ontologies. The aim of this paper is to identify plausible strategies for coping with ontological richness.

This paper presents a new method for zooming out an image. As the Impressionism is one of the most complete painting technique, able to preserve noticeable details and light effects, the method proposed in this paper is based on an impressionist approach. The input image is analyzed and described through impressionist characteristics that will be preserved when a zoom out will be realized. Thes...

A common objective in many applied problems is to infer properties of the interior of an object based on tomographic (line-integral) projections. In a number of applications the ultimate goal is to characterize (e.g., detect, locate) regions of the interior which are, in some sense, anomalous. A major challenge is to develop methods which can characterize anomalies directly in the data domain (...

We introduce a new zooming algorithm curvature interpolation method(CIM) based on partial differential equation, which produce high resolution(HR) color image by solving a linearized curvature equation. Partial Differential Equations (PDEs) have become an important tool for interpolation methods in image processing and analysis. CIM first evaluates the curvature of the low-resolution image, aft...

Content-based image retrieval attracted many researchers of various fields in an effort to automate data analysis and indexing. In contemporary image databases one finds many images with the same content perturbed by zooming, scaling, rotation and noise. For the purpose of image recognition in such databases we employ features based on statistics stemming from fractal transforms of gray-scale i...

The tuning of a constant velocity Kalman filter, used for tracking by a camera fitted with a variable focal-length lens, is shown to be preserved under a scale change in process noise if accompanied by an inverse scaling in the focal length, provided the image measurement error is of fixed size in image coordinates. Based on this observation, a practical method of zoom control has been built by...

Current photo browsers for personal photo collections mostly use the folder structure or camera-recorded time stamps as the only ordering principle. Some also allow manually provided meta-data (tags) for organizing and retrieving photos, but currently, only professional tools allow a pre-grouping of photos by image similarity. We believe that similarity is indeed a useful criterion both for ima...
