This paper presents a two-dimensional deformable model-based image segmentation method that integrates texture feature analysis into the model evolution process. Typically, the deformable models use edge and intensity-based features as the influencing image forces. Incorporation of the image texture information can increase the methods effectiveness and application possibilities. The algorithm ...

This paper presents a method which extends the use of genetic programming (GP) to a complex domain, texture segmentation. By this method, segmentation tasks are performed by texture classifiers which are evolved by GP. Small cutouts sampled from images of various textures are used for the evolution. The generated classifiers directly use pixel values as input. Based on these classifiers an algo...

In the present work, nano/ultrafine structured Al/Brass composite was produced by accumulative roll bonding (ARB) up to eight cycles. The evolution of grain refinement and deformation texture and their effect on the mechanical properties were investigated. It was observed that by increasing the ARB cycles, due to the difference in flow properties of the metal constituents, brass layers necked, ...

We describe non-standard techniques for optical studies of electrocon-vection structures in nematics. The time-resolved textures in the high frequency oscillatory regime are analyzed and compared with results of optical simulations. Conclusions on the relation between director pattern and optical texture are drawn. Using an additional phase plate in the optical setup , we monitor director twist...

In the present study, microstructure characteristic and texture evolution of TB18 titanium alloy were studied by isothermal hot compression under different strain with rate 0.001 s?1 0.1 in ? phase zone. Electron Back-Scattered Diffraction (EBSD) XRD used to characterize macrotexture. Microstructure demonstrated that coarse grains flatten elongated direction as increased. The dynamic recrystall...

One of the most challenging aspects of the microstructural evolution in polycrystalline materials is to understand the role of topological reconfigurations during coarsening. In this paper, we study these critical events in a one-dimensional grain-boundary system and a stochastic framework for modeling texture evolution. The model is based on a master equation derived from numerically determine...
