This paper proposes a segmentation scheme based on the joint usage of color and depth data together with a 3D surface estimation scheme. Firstly a set of multi-dimensional vectors is built from color, geometry and surface orientation information. Normalized cuts spectral clustering is then applied in order to recursively segment the scene in two parts thus obtaining an over-segmentation. This p...

This paper presents a novice heuristic algorithm, Water Flow-like Algorithm (WFA), for solving discrete optimization problems, particularly the bin packing problems. WFA simulates solution agents as water flows traversing the terrain mapped from the objective function. Governed by the gravitation force, water flows from higher attitudes to lower ones. Driven by the fluid momentum, water flows a...

This paper describes various manipulations of micro air bubbles using electrowetting on dielectric (EWOD): transporting, splitting, merging and eliminating. First, in order to understand the response of bubbles to EWOD, the contact angle modulation is measured in a capped air bubble and confirmed to be in good agreement with the Lippmann-Young equation until saturation. Based on the contact ang...

In this paper, a novel multiple motion object segmentation scheme based on homogenous region merging is presented. This scheme is based on utilization of a robust multiresolution motion estimator that can provide good motion estimates from irregularly-shaped regions. In addition, a novel region-merging criterion and an iterative region-merging process have been proposed. Experimental results de...

We examine and implement the concept of non-additive composition laws in the quantum theory of closed bosonic strings moving in (3 + 1)-dimensional Minkowski space. Such laws supply exact selection rules for the merging and splitting of closed strings.

the compact finite difference schemes have been found to give simple ways of reaching the objectives of high accuracy and low computational cost. during the past two decades, the compact schemes have been used extensively for numerical simulation of various fluid dynamics problems. these methods have also been applied for numerical solution of some prototype geophysical fluid dynamics problems ...
