Texture analysis is one of the fundamental aspects of human vision by which we differentiate between surfaces and objects. Texture refers to visual patterns or spatial organization of pixels. Texture classification is deals with identifying a given textured region from a given set of texture classes. Each of these regions has unique texture characteristics. Statistical methods are extensively used to determine the texture as a quantitative measure of the arrangement of intensities in a region…

Everyone around me always likes to comment on how physically weak I am. About how I’m “such a nerd” and how I should “grow up.” They don’t seem to care about anything else. It’s a cultural thing, really; I’m a white, American male in an American classroom. I’m supposed to be physically active, love sports, etc. But personally? I could never do that. It’s just not who I am. My parents have pretty similar opinions. They grew up in a time when the nerd was becoming a common thing, and when it…

Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…

micrometers, called pixels. The photon intensity is measured electronically on a scale of 256 gray values (0–255). Zero on this scale means that the maximum radiation is measured, which corresponds to black in the radiographic image, and 255 represents no radiation at all, or complete radiopacity. The measurements of the photon intensities for each pixel are sent to the computer and stored as an array of numbers representing the x and y coordinates and the photon intensity of each pixel. The…

and its height is 1.5 multiplied with its width. 2.2 Boundary detection To detect the boundary of the eye region it is important to first find middle positions between the two eyes. Then the upper and lower positions of the eyebrows are found. The pixels are scanned horizontally and vertically to find the lower and upper position of two eyebrows. The detection is lip is done by considering the lip box and calculating the distance between the forehead and eyes. Then the lower height of eyes and…

aesthetic there’s no contest – the iPhone 6 looks miles slicker than the S6. The new iPhone retains the 4.7-inch screen that Apple used on the iPhone 6, but the resolution is just 750 x 1,334 pixels (~326 ppi). The Galaxy S6 display is a 5.1-inch Super AMOLED screen and QHD resolution of 1,440 x 2,560 pixels and its easy to see why the Galaxy S6 is considered to have one of the best displays on the market. Galaxy S6 has a flat aluminum edge and the Gorilla Glass back while the Apple's curved…

Canon EOS M5: mirrorless wants to be a DSLR According to hundreds of comments on popular rumour websites, Canon may well have created a nice camera with their new mirrorless: the EOS M5 wants to be a… DSLR. In camera 5-axis image stabilizer that works in tandem with the lens IS, a centralized electronic viewfinder and a touch screen that works in tandem with said viewfinder, are some of the surprises inside the new EOS M5, which represents a shift for the M series from Canon. If all works as…

In modern society, no matter in real life or in the online world, advertisements are ubiquitous and incessantly remind people of their social status as consumers. Among the advertisements, some of them try to convince people of donation to charity, some of them aim to win votes for political groups while most of them attempt to promote the sale of products. With the advertising influences, people are caught up in the vicious circle of constantly consuming goods, even goods they do not really…

precisely the targets in which the Bubble Cursor tends to degenerates towards the point cursor. As part of an initial research, we discover the Bubble Cursor carried out inadequately once targets experienced a very good size smaller compared to 10 pixels. Making use of this limit for Bubble Lens within a 2nd research, we discovered that the Bubble Lens considerably outperformed the Bubble Cursor, reducing motion time period simply by 10.2% as well as error…
