Aiming at the problem of misdetection caused by traditional texture characteristic extraction model, which does not describe correlation among multiple bands, an object-oriented remote sensing image change detection method based on a color co-occurrence matrix is proposed. First, divided into multi-scale objects graph-based superpixel segmentation, and optimal scale determined overall goodness ...

Nail polish, in particular gel is the most commonly used cosmetic product. A component of which determines consumer color characteristics polish. Layered double hydroxides (LDH) are promising pigments. To expand range colors and shades pigments, use LDH with colored host guest cations promising. The parameters synthesis samples Zn-Co Cu-Co hydroxide pigments were studied. obtain Co as a cation ...

Solvent sensitive organic/inorganic hybrid one-dimensional photonic crystals (1DPCs) were prepared through alternating thin films of poly methyl methacrylate-co-hydroxyethyl methacrylate-co-ethylene glycol dimethacrylate (PMMA-co-PHEMA-co-PEGDMA) and titania nanoparticle sol by spincoating. Since the titania layer has a higher refractive index compared with the polymer layer, an obvious photoni...

Many stimulus attributes are represented in the cortex in the form of a map, such as the retinotopic map in the visual cortex and the frequency map in the auditory cortex where nearby cortical locations are associated with similar values of a given stimulus or action attribute. Given the computational advantage of maps for processing information,1 it is likely that a cortical region with a mapp...

Simske HP Laboratories HPL-2010-8 Payload density, grayscale pre-compensation, authentication The use of 2D color barcodes is quickly becoming commonplace on printed packaging and labels. The color barcode allows for a higher data density in comparison to its 1D or 2D black and...

In these days people are interested in using digital images. So the size of the image database is increasing enormously. Lot of interest is paid to find images in the database. There is a great need for developing an efficient technique for finding the images. In order to find an image, image has to be represented with certain features. Color, texture and shape are three important visual featur...

Green Supply Chain Management (GSCM) is an increasingly widely-diffused practice among companies that are seeking to improve their environmental performance. The motivation for the introduction of GSCM may be ethical (e.g., reflecting the values of managers) and/or commercial (e.g., gaining a possible competitive advantage by signalling environmental concern). Drawing upon a database of over 40...

This paper proposes a steganalysis technique for both grayscale and color images. It uses the feature vectors derived from gray level co-occurrence matrix (GLCM) in spatial domain, which is sensitive to data embedding process. This GLCM matrix is derived from an image. Several combinations of diagonal elements of GLCM are considered as features. There is difference between the features of stego...

There are numbers of methods prevailing for Image Mining Techniques. This Paper includes the features of four techniques I,e Color Histogram, Color moment, Texture, and Edge Histogram Descriptor. The nature of the Image is basically based on the Human Perception of the Image. The Machine interpretation of the Image is based on the Contours and surfaces of the Images. The study of the Image Mini...

The objective of this in vitro study was to assess the color change of resin nanocomposites exposed to a cola beverage at different times. Seventy-five cylinders (10 mm x 2 mm) were prepared from each of 4 resin-based composite materials, 3 nanocomposites (Filtek Supreme, Tetric EvoCeram, Premise) and 1 microhybrid (Filtek Z250), to give a total of 300 specimens. Specimens in each group were di...
