Moving shadow detection is a challenging task in computer vision applications, such as surveillance, video conference, visual tracking, object recognition, and many other important applications. In this paper, region-based moving shadow detection using affinity propagation (RMSDAP) is presented, which detects shadows in terms of texture similarity. Firstly, we divide foreground image into no ov...

We briefly describe the design of a course on “Systems Analysis and Process Innovation”, focusing especially on its project assignments. Students are introduced to process modeling and data modeling, followed by i* and Value Network modeling. In their project assignments, students apply these modeling techniques to real organizational settings to analyze an as-is situation and to explore to-be ...

This paper presents design methods for boundary filters for the processing of finite-length signals. In particular, it is shown how vanishing moments can be imposed during the design. Applications are found in segmentation-based audio and shape-adaptive image compression.

Regulatory policy in telecommunications is desperately in need of mid-level theory. There is widespread consensus that regulators should try to promote competition. There is also bitter contention about what this implies for particular industry battles. For example, an industry observer declared, “Competition should be the policy. And code that enables competition should be the rule.” He then w...

Though structured illumination (SI) microscopy is a popular imaging technique conventionally associated with fluorescent super-resolution, recent works have suggested its applicability towards sub-diffraction resolution coherent imaging with quantitative endogenous biological contrast. Here, we demonstrate that SI can efficiently integrate together the principles of fluorescent super-resolution...

Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In...

Psychophysical two-tone suppression and the growth of the (2f• --f2} and • --f•) distortion products were measured in four normal-hearing young adults using a forward-masking paradigm. The stimulus parameters investigated were: (1)f• = 750 and 3000 Hz; (2)f2/f• = 1.1 l, 1.26, and 1.41; (3) L• = 50, 65, 80, and 90 dB SPL; and (4) L2 -L• varied from -20 to + 20 dB in 10-dB increments. It appears ...

in order to study the effect of sowing date and plant density on some quantitative traits and yield of sugar beet genotypes a field experiment was carried out at sugar beet seed production research station of karaj in 2006. treatments arranged in a split, split plot experiment based on completely randomized block design with four replications. the main factors were two sowing dates as 14 april ...

In this chapter, various synthesis routes for PZT powders and fabrication processing techniques for PZT ceramics and films are reviewed. Emphasis is placed on chemical routes, especially the hydrothermal synthesis of PZT powders. The principles of the colloidal chemistry in ceramic suspension and its application to the colloidal processing of ceramics and films, especially when using sub-micron...
