This paper addresses vision-based people counting under the assumption of an oblique stationary camera setup without any usage of tracking. Our approach is based on motion detection and blob analysis. The estimation of the number of people in the scene is done by accumulating the estimation values of each blob. The blob specific estimation values are computed using four input values: the minimu...
The present study involves a novel computational technique, regarding simultaneous use of the pseudo particle method, Poisson integral method and a special-purpose computer originally designed for molecular dynamics simulations (MDGRAPE-3). In the present calculations, the dynamics of two colliding vortex rings have been studied using the vortex method. The present acceleration technique allows...
This study uses Blob Analysis technique to optimize Gaussian Mixture Model method performance in detecting and counting cars and motorcycles under heavy traffic conditions. It is profound that by optimizing the minimum and maximum blob area in order to obtain proper blob size from a video image’s region of interest will also improve the accuracy of system. The result shows that appropriate para...
This paper presents a new criterion for blob detection applied in the framework of scale-space based segmentation of objects from digital medical images. The proposed method is based on fitting the blob to a standard shape, such as the Gaussian, subject to constraints based on the blob support area or the total variation. The method has been verified and compared with the conventional procedure...
Blob-like structures occur often in nature, where they aid in cueing and the pre-attentive process. These structures often overlap, form perceptual boundaries, and are heterogeneous in shape, size, and intensity. In this paper, voting, Voronoi tessellation, and level set methods are combined to delineate blob-like structures. Voting and subsequent Voronoi tessellation provide the initial condit...
In this paper, we propose a novel practical method for blob-based liquid 3D morphing. Firstly, blobby objects are employed to approximate a given polygonal surface. The primitives in the medial axis sphere-tree of a polygonal model are utilized as initial blobs— this greatly improves the robustness and efficiency of the blob-based approximation. Secondly, we establish the blob correspondences b...
We consider a special configuration of vorticity that consists of a pair of externally tangent circular vortex sheets, each having a circularly symmetric core of bounded vorticity concentric to the sheet, and each core precisely balancing the vorticity mass of the sheet. This configuration is a stationary weak solution of the 2D incompressible Euler equations. We propose to perform numerical ex...
We consider the 3D incompressible Navier–Stokes equations under following 2 + 1 2+\frac {1}{2}</mml:annotatio...
In advanced security and automated surveillance systems, Object Recognition and Classification plays a vital role. Motion Based Recognition has been improved by using Recurrent Motion Image (RMI) classifier. For efficient Object Recognition the input video frames endures Preprocessing method such as (i) Background Subtraction using Linf distant image method, (ii) Shadow Points located by transf...
The striate cortex of macaque monkeys contains an array of patches which stain heavily for the enzyme cytochrome oxidase (CO blobs). Cells inside and outside these blobs are often described as belonging to two distinct populations or streams. In order to better understand the function of the CO blobs, we measured the contrast sensitivity and spatial frequency response of single neurons in and a...
