The retrieval using single feature has a certain limitation, which fails to comprehensively describe an image. Aiming at such retrieval defect, this paper proposes an image retrieval method integrating color and texture. Firstly, carry out image segmentation with uniformly-spaced method, and then extract color feature of each segmentation with weighting processing done; and then, extract textur...

We generate bolometric light curves for a variety of type Ia supernova models at late times, simulating gamma-ray and positron transport for various assumptions about the magnetic field and ionization of the ejecta. These calculated light curve shapes are compared with light curves of specific supernovae for which there have been adequate late observations. From these comparisons we draw two co...

The majority of scientific papers focusing on wood classification for pencil manufacturing take into account defects and visual appearance. Traditional methodologies are based on texture analysis by co-occurrence matrix, by image modeling, or by tonal measures over the plate surface. In this work, we propose to classify plates of wood without biological defects like insect holes, nodes, and cra...

Magnetic and magneto-optic properties of sputtered Co/Ni multilayers" (1994). Roger Kirby Publications. Paper 17. We have investigated the magnetic and magneto-optic properties of Co/N multilayers deposited on Ag and Au buffer layers. The samples with Au buffer layers show perpendicular magnetic anisotropy, but those with Ag buffer layers do not. The. structure and degree of crystaIIine alignme...

This paper describes methods and results archived by our research group at the Cross Language Evaluation Forum (CLEF’2009). In our work we concentrated on the medical image retrieval task. All the attention was given to the retrieval based on nine visual topics only. No textual information was considered. Our goal was to develop and comparatively assess image descriptors for content based retri...

Modeling of semantic space is a new and challenging research topic both in cognitive science and linguistics. Existing approaches can be classified into two different types according to how the calculation are done: either a word-by-word co-occurrence matrix or a word-by-context matrix (Riordan 2007). In this paper, we argue that the existing popular distributional semantic model (vector space ...

This review steps back from the burgeoning economics literature on measuring social preferences and considers more carefully the empirical evidence from the lab and the field. I place the claims from the ardent supporters of the literature into three bins: one for claims that are supported by the data upon closer scrutiny, one for claims that are not supported by the data upon closer scrutiny, ...

Developmental instability is used commonly to assess environmental conditions, but it is frequently observed that some traits, individuals, and species are better indicators of environmental stress than others. Herein we addressed the mechanisms behind this variation by examining stress-induced developmental instability in three coexisting species of soricid shrews. We examined jaw development ...

Image splicing is a common operation in image forgery. Different techniques of image splicing detection have been utilized to regain people’s trust. This study introduces a texture enhancement technique involving the use of fractional differential masks based on the Machado entropy. The masks slide over the tampered image, and each pixel of the tampered image is convolved with the fractional ma...
