We prove the convergence of vortex blob methods to classical weak solutions for the twodimensional incompressible Euler equations with initial data satisfying the conditions that the vorticity is a finite Radon measure of distinguished sign and the kinetic energy is locally bounded. This includes the important example of vortex sheets. The result is valid as long as the computational grid size ...

The blob detection methods plays the vital role in the various image processing models. The blob detection models are utilized for the localization of the visible objects in the given images in order to understand the type and size of the objects. The blob detection can be utilized for the classification, categorization and other purposes in the image processing models. In the proposed model, t...

The results of three-dimensional numerical simulations of mass transfer in binaries with spiral shocks are presented. It is shown that the mass transfer rate variation disturbs the equilibrium state of accretion disk and results in formation of the blob. This dense formation moves on the disk with variable velocity. The results of our simulations show that the blob lives long enough and retains...

Recently, it was reported that the evidence of non-diffusive (that is, convective) plasma transport from the edge of core plasma to the first wall in magnetic confinement fusion devices. Such a transport is thought to be provided by intermittent filamentary coherent plasma structures “blobs” in scrape-off layer (SOL) [1]. Many theoretical and numerical studies about blob dynamics have been perf...

This paper introduces a tool to semi-automatically generate meta-data from game sprite sheets. MuSSE is a tool developed to extract XML data from sprite sheet images with non-uniform – multi-sized – sprites. MuSSE (Multi-sized Sprite Sheet meta-data Exporter) is based on a Blob detection algorithm that incorporates a connected-component labeling system. Hence, blobs of arbitrary size can be ext...

This paper proposes an object detection method using the methods of variable size blob detection along with feature stability. The objective of this algorithm is for detecting variable size and variable shape objects without the use in preceding information of the object of interest. Process of the algorithm constructs a scalespace tree from blobs detected from a series of images after blurring...
