Background modeling is an important issue in video surveillance. A sophisticated and adaptive background model can be used to detect moving objects which are segregated from the scene in each image frame of the video via the background subtraction process. Many background subtraction methods are proposed for video acquired by a stationary camera, assuming that the background exhibits stationary...

The local identification of communities in a network can be much more effective than partitioning the entire network when only a small portion of a large network is of interest. A local approach is also favored when it is difficult to obtain information about the entire network, the world wide web is a prime example. Such local identification algorithms typically evaluate nodes outside the loca...

Th is article examines the relationship between electronic participation (e-participation) and trust in local government by focusing on fi ve dimensions of the e-participation process: (1) satisfaction with e-participation applications, (2) satisfaction with government responsiveness to e-participants, (3) e-participants’ development through the participation, (4) perceived infl uence on decisi...

ABSTRACT A model for deriving perceived local speech rate directly out of the speech signal is developed based on perception experiments. Since local speech rate modifies acoustic cues (e.g. transitions and voice-onset time [5]), phones [1, 4, 7, 19], syllables [3, 15], and even words, it is one of the most important prosodic cues. Our local speech rate estimation method is based on a linear co...

Theoretically, metric solid shape is not determined uniquely by shading. Consequently, human vision has difficulty in categorizing shape when shading is the only cue. In the present research, subjects were required to categorize shaded quadric surfaces. We found that they were rather poor at this task; they confused hyperbolic and elliptic (both convex and concave) shapes easily. When a cast sh...

sustainable tourism development is a process that interacts with host life quality, visitor′ demands and preservation of natural and human environment. in the sustainable tourism approach, with an emphasis on the key function of hosts and guests' perception to understand and constantly evaluate their beliefs and imaginations toward tourism development in destination, subjective indicator...

OBJECTIVE To investigate the evaluation of local government Web sites carrying information on infertility by infertile women and by government staff. In particular, the study investigated whether the women and staff differed with respect to the information they rate as important and their self-reported satisfaction with the Web sites. DESIGN AND SAMPLE Cross-sectional descriptive study. Sixty...
