The zebrafish (Danio rerio), traditionally used in genetics is now becoming increasingly popular in behavioural neuroscience. Zebrafish is a small teleost (bony) freshwater fish originating from northern India, used worldwide in research in most stages of development from embryo to adult. While, a couple of papers on zebrafish related to visual colour discrimination and learning have been publi...

We present a method to give (fused) multiband night-time imagery a natural day-time colour appearance. For input, the method requires a false colour RGB image that is produced by mapping three individual bands (or the first three principal components) of a multiband nightvision system to the respective channels of an RGB image. The false colour RGB nightvision image is transformed into a percep...

in this research we described the effective hamiltonian theory and applied this theory to the calculation of current-current (q1,2) and qcd penguin (q3,…,6) c quark decay rates. we calculated the decay rates of semileptonic and hadronic of charm quark in the effective hamiltonian theory. we investigated the decay rates of d meson decays according to spectator quark model (sqm) for the calculati...

Virtual environments provide a whole new way of viewing and manipulating 3D data. Current technology moves the images out of desktop monitors and into the space immediately surrounding the user. Users can literally put their hands on the virtual objects. Unfortunately, techniques for interacting with such environments are yet to mature. Gloves and sensor-based trackers are unwieldy, constrainin...

Content-Based Image Retrieval systems can often return poor results when attempting to match images with extraneous feature information such as complex backgrounds, shadows, or frames. As a solution, this project aimed to provide a semi-automatic object extraction tool, the 'Intelligent Flood Fill'. This tool would also help users of graphics packages, who can find current object extraction too...

The importance and use of text extraction from camera based coloured scene images is rapidly increasing with time. Text within a camera grabbed image can contain a huge amount of meta data about that scene. Such meta data can be useful for identification, indexing and retrieval purposes. While the segmentation and recognition of text from document images is quite successful, detection of colour...

Despite their shortcomings, gradient and second derivative operators remain popular as edge detectors because human beings usually do not show strong directional preferences when detecting edges or boundaries. However, in a colour image an edge can be given not only if the respective brightness values of two neighbouring pixels are significantly different, but also if their chromatic components...

Introduction: Humic substances (HSs) are very complex and heterogeneous organic matter with high molecular weight and various functional groups, which are produced from the chemical and biological degradation of plants and animal tissues. HS can cause: colour, odour and taste problems in drinking water, biological growth in distribution systems, increase in chlorine demand for disinfection, mem...

Almond cake is a by-product of mechanical press extraction almond oil intended mainly for the cosmetics industry. According to circular economy zero waste, purpose reuse this byproduct prepare natural gluten-free flour replace part or all whole soft wheat (SWF) in specific foods. The after grinding was sifted on sieving shaker equipped with 4 mesh sieves 1mm, 500µm, 250µm, and 100µm. obtained f...

How well can categorical colour perception be maintained in natural environments with varying illuminants? To address this question, a colour-naming experiment was performed with colour-monitor images of natural scenes simulated under two different daylights of correlated colour temperature 6500 K and 25000 K. Images were obtained from a set of hyperspectral data to enable the accurate control ...
