This paper describes a new technique for object recognition based on learning appearance models. The image is decomposed into local regions which are described by a new texture representation derived from the output of multiscale, multiorientation filter banks. We call this representation “Generalized Second Moments” as it can be viewed as a generalization of the windowed second moment matrix r...

Perceptual watermarking in the wavelet domain has been proposed for a blind spread spectrum technique, taking into account the noise sensitivity, texture and the luminance content of all the image subbands. In this paper, we propose a modified perceptual mask that models the human visual system behavior in a better way. The texture content is appreciated with the aid of the local standard devia...

This paper describes a new technique for object recognition based on learning appearance models. The image is decomposed into local regions which are described by a new texture representation called “Generalized Second Moments” that are derived from the output of multiscale, multiorientation filter banks. Class-characteristic local texture features and their global composition is learned by a h...

Calcification rarely occurs in vestibular schwannoma (VS), and only seven cases of calcified VS have been reported in the literature. Here, we report a 48-year-old man with VS, who had a history of progressive left-sided hearing loss for 3 years. Neurological examination revealed that he had left-sided hearing loss and left cerebellar ataxia. Magnetic resonance imaging and computerized tomograp...

The objective of this in vitro study was to evaluate the effect of three surface treatments and two adhesive systems on the shear bond strength of old and freshly placed amalgam. The results suggested that the intact amalgam showed a significantly higher strength than repaired groups and the strongest repaired specimens were made when the amalgam surfaces were roughened with a diamond bur or mi...

Grouping images into semantically meaningful categories using low-level visual feature is a challenging and important problem in content-based image retrieval. The groupings can be used to build effective indices for an image database. Digital image analysis techniques are being used widely in remote sensing assuming that each terrain surface category is characterized with spectral signature ob...

To date, very little is known about the normal development trajectory of visual texture segregation, or how it is affected by preterm birth. The goal of this study was to characterize the development of visual texture segregation using texture segregation visual evoked potentials (tsVEPs) in children born full-term and children born preterm without major neurological impairment. Forty-five full...

Abstract Calotropis gigantea is a plant not widely used but has potential as medicinal plant. The phytochemical compound can be produced faster using tissue culture and combination of growth regulators. research objectives were to study the effect determine best concentration BAP 2,4-D in callus induction . This was carried out Plant Physiology Biotechnology Laboratory, Faculty Agriculture, Seb...

A 28-year-old man with long-standing right proptosis presented with an extensive multilobulated partially cystic orbital mass thought to be a lymphangioma. Because of concern that excision or debulking of the lesion was likely to be complicated by excessive bleeding, the lesion was injected with a mixture of ethiodized oil (Ethiodol) and cyanoacrylate glue under direct observation. The mixture ...

Ethical leadership involves the execution of a behavioral pattern in which a man or woman attempts to lead from a virtuous set of values and beliefs. Ethical leadership investigates relationships between ethical leaders and follower outcomes with more research needed on organizational identity and outcomes. This research provides a socio-rhetorical analysis of Old Testament texture to investiga...
