Image segmentation is the initial step in image analysis and pattern recognition. Image segmentation refers to partitioning an image into different regions that are homogenous or similar in some characteristics. Color image segmentation attracts more and attention because color image color images can provide more information than gray level images. Basically, color image segmentation approaches...

One challenge in the model-based design of mechatronic systems is to integrate a variety of different physical principles into one single, combined model of an entire system. In addition, for rapid control prototyping and hardwarein-the-loop scenarios, models need to be executed under real-time conditions, connected to real hardware. The open design environment presented here is based on proces...

We propose a new method for representing the topology and geometry of 2D compact surfaces embedded in a three-dimensional space. Topology is modeled through a skeletal graph, where a distance function is employed as a Morse function. Invariance to rigid transformations follows directly from this choice of Morse function. Geometry is captured by modeling the evolution of level curves of the dist...

In [12] Stolfi developed a complete theory of Oriented Projective Geometry. He showed that assigning meaning to the sign of an otherwise homogenous representation of geometry could provide a multitude of benefits. This paper extends his work by applying the same approach to Conformal Geometric Algebra. Oriented Conformal Geometric Algebra allows intuitive manipulation of such concepts as half-s...

We consider the specialization to spatially homogenous solutions of the Jacobson formulation of N=1 canonical supergravity in terms of Ashtekar’s new variables. We find that the classical Poisson algebra of the supersymmetry constraints is preserved by this specialization only for Bianchi type A models. The quantization of supersymmetric Bianchi type A models is carried out in the triad represe...

Healthcare is most effectively delivered by high-performance teams, which require, not simply talent, but also diversity in their members, supported a culture of equity that open, supportive, and inclusive. Cognitive offers performance advantage, improving collective understanding optimizing high-complexity problem solving. Diverse teams have been shown to outperform homogenous team, this diver...

In this paper we consider the class (θA, B) of parameter-dependent linear systems given by matrices A ∈ ℂn×n and B ℂn×m. This is interest for several applications frequently met task such to steer origin toward a target family f(θ) using an input that independent from parameter. provides collection necessary sufficient conditions ensemble reachability these systems.
