Abstract
Many old manuscript documents were written on both sides of the paper, and the bleed-through from one side of the document to the other increases the difficulty in reading or deciphering the information on the page. This paper presents techniques for reducing such ble ....etc

Abstract

Character segmentation and detection play a very important role in the automatic license plate recognition (ALPR) system. For accurate character segmentation first need is to remove skew from the received license plate. Skew is the angle by which the image seems to be deviated from its perceived steady state position. To solve the problem, a combined approach for skew correction of vehicle license plates (VLP) is proposed which is based on Harris corner detector and principal component analysis (PCA). First, corner points are extracte ....etc

SKEW: An Efficient Self Key Establishment Protocol for
Wireless Sensor Networks

INTRODUCTION:
Wireless Sensor Networks architectures can generally be organized in two
ways: distributed and hierarchal. A hierarchical WSN has a network hierarchy based on factors like power and memory among the sensor nodes. The Cluster heads collect local or received data and send them to base stations. Cryptography keys in the protocols used in WSNs are transmitted within nodes via messages and thus incur heavy overheads. A sender node has 2 options ....etc

Thanks in advance

We have done 3 bit error correction for 8 bit orthogonal codes. but how can we detect 7 bit errors in the case of 16 bit orthogonal codes as in general we can detect (n/2-1) bits? ....etc
