In this paper we address the problem of estimating and analyzing the motion in image sequences showing uid phenomenon. Due to the great deal of spatial and temporal distortions that luminance patterns exhibit in images of uid, standard techniques from Computer Vision, originally designed for quasi-rigid motions with stable salient features, are not well adapted in this context. In that prospect...

Flow visualization has a long tradition in scientific data visualization. Approaches for 3D vector fields however have only recently experienced a boost due to the introduction of programmable graphics hardware with large texture memory. Consequently, volumetric flow visualization has entered many disciplines of science and engineering including mechanics, physics, chemistry, meteorology, geolo...

Deep Convolutional Neural Networks (CNNs), such as Dense Network (DenseNet), have achieved great success for image representation learning by capturing deep hierarchical features. However, most existing network architectures of simply stacking the convolutional layers fail to enable them fully discover local and global feature information between layers. In this paper, we mainly investigate how...

Now a day’s security is an important aspect to be considered, so a framework is proposed in this paper that is used to segment flow of dense crowds. The flow field that is generated by the movement in the crowd is treated just like an aperiodic dynamic system. On this flow field a grid of particles is put over for particle advection by the use of a numerical integration scheme. Then flow maps a...

Vector field visualization approaches can broadly be categorized into approaches that directly visualize local or integrated flow and approaches that analyze the topological structure and visualize extracted features. Our goal was to come up with a method that falls into the first category, yet reveals structural information. We have developed a dense flow visualization method that shows the ov...

Segregation in a dense solid-liquid multiphase flow is complicated by its interactions between phases. In this paper, the segregation of dense solid-liquid flow was simulated using the Finite Volume Method. A Euler-Euler multiphase simulation was conducted for the dense solid-liquid flow. The flow in the viscous regime was evaluated using kinetic theory describing the flow of smooth, slightly i...
