Visual cryptography encodes a secret image into n shares which are distributed to n participants. Pixel Sieve method was proposed recently to encode an image into shares, but the encryption quality is poor. In this paper an improved version of pixel sieve method is proposed to achieve more security then existing pixel sieve method. Based on cross merge and(More)
The end-effectors of the manipulator are required to move in a particular fashion to accomplish a specified task. The execution of the specific task requires the manipulator to follow a preplanned path, which is the larger problem of motion or trajectory planning and motion control for the manipulator. The goal of trajectory planning is to describe the(More)
A deep knowledge of process execution behavior is very useful in formulating better scheduling techniques. In this paper we study the approaches to the process characterization problem. Also we propose a novel method to characterize and categorize process execution behaviors by using machine learning techniques that learn from previous execution instances(More)
Noise reduction in speech applications has a significant amount of research for several decades. The ultimate goal of the speech signal processing research is to develop systems which can perform well in noisy environments. The main objective of this research work is to obtain a clean speech signal of higher quality by applying the optimal noise(More)
— Kalman filter is a well known adaptive filtering Algorithm, widely used for target tracking applications. When the system model and measurements are non linear, variation of Kalman filter like extended Kalman filter (EKF) and Unscented Kalman filters (UKF) are used. For obtaining reliable estimate of the target state, filter has to be tuned before the(More)
Testing of software is one of the most important phases in the software development life cycle. Testing is performed to ensure the quality of the product developed. As the software system grows, it becomes more and more difficult to test the entire system. Thus, testing minor changes in the software became difficult. Regression testing was introduced to(More)
