the study area is a part of the sanandaj-sirjan metamorphic belt comprising low- to high-graderegional and contact metamorphic rocks that are intruded by various plutonic bodies. garnet crystals areabundant in pelitic schists, amphibole schists, migmatites, hornfelses and aplites. they are mostly almandinerich(xalm>60) pyralspite garnets and show dodecahedron, trapezohedron and mixed (dodecahed...

The level set representation of shapes is useful for shape evolution and is widely used for the minimization of energies with respect to shapes. Many algorithms consider energies depending explicitly on the signed distance function (SDF) associated with a shape, and differentiate these energies with respect to the SDF directly in order to make the level set representation evolve. This framework...

in 1909, several years before the famous `organizer’ experiments of spemann and mangold, ethel browne demonstrated induction of a secondary axis in hydra by grafting a hypostome. based on this and subsequent work, in the late sixties, lewis wolpert proposed the theory of morphogen gradients and positional information. we have studied secondary axis induction by hypostome and foot tissue using t...

In this paper we present an study on the importance of the grid configuration in gender recognition from whole body static images. By using a simple classifier (AdaBoost) and the well-known Histogram of Oriented Gradients features we test several grid configurations. Compared with previous approaches, which use more complicated classifiers or feature extractors, our approach outperforms them in...

In this paper, a system for facial recognition to identify missing and found people in Hajj and Umrah is described as a web portal. Explicitly, we present a novel algorithm for recognition and classifications of facial images based on applying 2DPCA to a 2D representation of the Histogram of oriented gradients (2D-HOG) which maintains the spatial relation between pixels of the input images. Thi...

An image of an eye is known to have a certain shape, roughly ellipse shaped. And so the Histogram of Oriented Gradient (HOG) feature is a good descriptor for this type of detection. In this paper, the eye detector is trained with HOG features using an Adaptive Boosting (AdaBoost) algorithm to train and learn a set of weak classifiers. It is shown to work fairly well although it underperforms wh...
