Zdefiniowano i omówiono wymagania dotyczące pracy symulatora pojazdu szynowego, a także wymagania konstrukcyjne dotyczące zarówno...
Space missions are often equipped with several high definition sensors that can autonomously collect a potentially enormous amount of data. The bottleneck in retrieving these often precious datasets is the onboard data storing capability and the communication bandwidth, which limit the amount of data that can be sent back to Earth. In this paper, we propose a method based on the analysis of brain...
We propose a probabilistic model for the relevance feedback of users looking for target images. This model takes into account user errors and user uncertainty about distinguishing similarly relevant images. Based on this model, we have developed an algorithm, which selects images to be presented to the user for further relevance feedback until a satisfactory image is found. In each query session,...
A method of similarity clusters detection in large visual databases is described in this work. Similarity clusters have been defined on the basis of a general concept of similarity measure. The method is based also on the properties of morphological spectra as a tool for image presentation. In the proposed method similarity of selected spectral components in selected basic windows are used to similarity...
A method for browsing large compressed images over the Internet is presented. Images are compressed using a very recent coded file format, referred to as JPEG XR, designed primarily for storage of continuous-tone photographic images and currently at the beginning of the ISO/IEC standardization process. In the proposed method, region of interest specified by the user are progressively downloaded and...
Image presentation using a projector requires a white screen. As the presentation with a projector becomes popular, image projection on any surface has been desired increasingly. To project images on any surface without giving viewers annoyance, the radiometric compensation is needed. This study focuses on the transfer function of the projector and on the distribution map of color on the projected...
In contrast with PCA, the two-dimension presentation technique (TDP) developed recently is very efficient. With TDP, we can easily extract feature vectors of an image matrix by projecting the image matrix rather than the corresponding vector onto projecting axes. In this paper, we present complete properties of TDP in detail and the property of decorrelation associated with TDP is originally revealed...
