    change (Solomona et al., 2006). The productivity of forest is pigeonholed by the appropriate temporal and spatial changeability under the influence of the climate, the soil and the physiological types of the forest (Davis et al., 2012). Based on the spectral characteristics, indices have been articulated to accentuate features of interest on the remotely sensed data. Several research embrace productivity

    lf of Mexico to the north (station 15) in Little Lake during 2010 (10 months) and 2011 (5 141 months) (Figure 1). Surface temperature and salinity were recorded in-situ using a handheld Yellow 142 Springs Instruments (YSI) multi-probe field meter. Water samples were stored in a cooler and brought 143 back to the laboratory on the same day. The samples were immediately filtered using pre-rinsed 0.2 μm Remote Sens. 2015, 7 5 Nuclepore membrane filters (Whatman GmbH) and analyzed for optical 144 absorption

    MelaFind optical scanner is an hand-held device that is the size of a blow dryer that has an image probe that contains 10 multi spectral images. After scanning over a suspicious skin mole the device evaluates multispectral images into 10 spectral bands, from blue to infared. Then these images are processed with a software 10 digital images in less than one minute. This displays 3D images of moles and sees 2.5 mm below surface of the skin. Also, this provides record to patients so they are

    radiance from the water surface (sky light) and radiance reflected from whitecaps. The raw at-sensor radiance images were corrected for atmospheric effects using the ENVI v 5.2 (ITT Visual Information Solutions, Inc.) FLAASH (Fast Line of sight Atmospheric Analysis of Spectral Hypercubus) module. FLAASH converts radiometrically-calibrated at-sensor radiance images to surface reflectance images by incorporating the MODTRAN4 radiative transfer code.

    [21]. The computation of the variance covariance matrix (C) of multiband images is expressed as: Where M and X are the multiband image mean and individual pixel value vectors respectively, and n is the number of pixels. In change detection, there are two ways to relate PCA. The first method is counting two image dates to a single file, and the second methods is subtracting the second image date from the corresponding image of the first date after performing PCA individually. The disadvantages

    Simulations of galaxy formation based on the Lambda Cold Dark matter (ΛCDM) cosmological model predict that a large galaxy such as the Milky Way should have many (~ 200) dwarf satellite galaxies. However, only about 20 or 30 have been identified. Where are the rest? Warm dark matter, constituting of sterile neutrinos, is lighter and since dwarf galaxies consisting mainly of dark matter are so difficult to find by visible light, there could be enough of them to reconcile the large number of dwarf

[9] orthogonal locality preserving projection (OLPP) method Novel face recognition method based on projections of high-dimensional face image representations into lower dimensionality and highly discriminative spaces. Tested for a number of datasets and it is found that accuracy of image recognition for proposed approach is higher. The results are evaluated for different resolutions of the image and it is found that even for low resolution accuracy

    1. Introduction Quantitative urban studies are becoming increasingly important for planners knowing that in the year 2015 more than half the global population will be residing in cities [1]. Suitable urban planning ought to be a top priority for future development but unfortunately sound planning has not taken place especially in many African cities as heavy rural-urban migration continues to cause cities to expand at uncontrollable rates [2]. As a consequence, the urban population in Africa is

    Using IM, the watermark is embedded into the chosen multiwavelet coefficients by quantizing the coefficients. Scrambled watermarks are generated using a set of secret keys, and each watermark is embedded in each motionless scene of the video. The multi-wavelet transform uses two transformations such as Haar transform and Doubchies transform. The work is done with the help of designed user interface. This method extracts the secret message correctly and this provides better performance. Keywords:-
