Abstract There are many approaches to detect hand gestures. To narrow the search region, most existing methods construct fixed postures. However, under natural condition it is not realistic to make a user stick on a certain pose. In this paper a method to quickly detect hand shape quickly and robustly is experimented.

However, under natural condition it is not realistic to make a user stick on a certain pose. In this paper a method to quickly detect hand shape quickly and robustly is experimented. Firstly, a skin color detector will be utilized to detect the presence of a hand in the image, then a set of image is clustered using k-mediod algorithm. Next, a tree structure of boosted cascades will be constructed. A general hand detector is provided by the main tree while the branches will classify valid shapes. Our experiments show a detection rate of 80% and from that 85% is achieved for recognition. Read More Read Less

We are involved in this research study methodology for hide data within different texts. That’s where the data masking process is one of the areas of information security to hide and encrypt data and other branches that represent information security. The process of hiding data within the text are completely different from the rest of methods of concealment, it will be through a change in the empty spaces in the text or change the text itself or change in some of the properties other than text and empty spaces. These changes are a way by which to hide data within the text. This research proposes an enhancement of white space method for hiding data, which is processed by changing the secret text through extracting the indexes of the characters from the cover text or ASCII code, then converting these numbers from the decimal numeral system into the octal numeral system in order to use the number 8 and 9 as indicators against the remaining numbers. Then, merge these outcomes with the white spaces between the words in the cover text by changing the font size of these numbers to 1pt, and changing the font color to match background color of the cover text.
