Figure 1: Connecting the appearance and window position spaces. A window tight on the baseball (green star in the appearance space plot) and some larger windows containing it (red circles in the appearance space). Black points in appearance space represent all other candidate windows. The appearance space plots are actual datapoints, representing windows in 3-dimensional Associative Embedding o...
We propose a novel method to avoid stereo window violations at screen borders. These occur for objects in front of the zero parallax plane, which appear (physical) screen, and that are clipped one eye while still being visible other eye. This contradicts cues, particularly disparity, potentially resulting strain simulator sickness. In interactive dynamic virtual environments, where user control...
In this paper a novel moving shadows detecting algorithm is proposed. The algorithm can be used in indoor and outdoor environments. The algorithm we propose fuses together color and stereo disparity information using the Dempster-Shafer combination rule. Some considerations on the nature of the shadow improves the algorithm’s ability to candidate the pixels as shadow or foreground. The candidat...
The common spatial patterns (CSP) algorithm is the most popular filtering method applied to extract electroencephalogram (EEG) features for motor imagery (MI) based brain-computer interface (BCI) systems. effectiveness of CSP depends on optimal selection frequency band and time window from EEG. Many algorithms have been designed optimize CSP, while few seek window. This study proposes a novel f...
For several years, mutual information (MI) has been the classic multimodal similarity measure. The robustness of MI is closely restricted by the choice of MI window sizes. For unsupervised human monitoring applications, obtaining appropriate MI window sizes for computing MI in videos with multiple people in different sizes and different levels of occlusion is problematic. In this work, we apply...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
This paper presents a segmentation-based stereo matching algorithm using an adaptive multi-cost approach, which is exploited for obtaining accuracy disparity maps. The main contribution is to integrate the appealing properties of multi-cost approach into the segmentation-based framework. Firstly, the reference image is segmented by using the mean-shift algorithm. Secondly, the initial disparity...
A Study of the Essence of the Cinematic Frame According to the Metaphors of the Window and Framework
The cinematic frame is the boundary between the cinematic image and the outside world. In the history of theoretical studies of cinema, the essence of the cinematic frame is analyzed in many ways. Here we focus on two significant viewpoints among them. One of these significant viewpoints considered cinematic frame as a window, and another one considered it as a framework. Both of them had (and ...
Weighted flow networks are structures that arise naturally when analyzing complex systems. The countable properties of unweighted networks are not easily generalized to weighted networks. One candidate measure of complexity is the number of roles, or specialized functions in a network. It is easy to identify the number of roles in a linear or cyclic unweighted network. There is only one logical...
