Online signature verification using angular transformation for e-Commerce services.
January 1, 2010 ... I. INTRODUCTION RECENTLY, the growth of purchasing merchandises via electronic online services so-called e-Commerce has been rapidly driven by huge user demand. However, the technology of user authorization is still based on numeric or...

Edge segmentation of satellite image using phase congruency model.(Report)
January 1, 2010 ... I. INTRODUCTION IN computer vision object detection have a significant role in image analysis. Several gradient-based edge detector methods have been developed. These methods are sensitive to edge magnitude, smoothness and magnification. To...

Overloading scheme for cellular DS-CDMA using quasi-orthogonal sequences and iterative interference cancellation receiver.
January 1, 2010 ... I. INTRODUCTION THE number of users supported in a DS-CDMA cellular system is typically less than spreading factor (N), and the system is said to be underloaded. Overloading is a technique to accommodate more number of users than the...
