Optimization plays a critical role in human modern life. Nowadays, optimization is used in many aspects of human modern life including engineering, medicine, agriculture and economy. Due to the growing number of optimization problems and their growing complexity, we need to improve and develop theoretical and practical optimization methods. Stochastic(More)
In this paper we present the Dempster-Shafer theory as a framework within which the results of a Bayesian Network classifier and a fuzzy logic-based classifier are combined to produce a better final classification. We deal with the case when the two original classifiers use different classes for the outcome. The problem of different classes is solved by(More)
This paper deals with a recently proposed non-parametric approach to camera calibration, which is applicable to any type of sensor design. Currently, no relative quantitative performance data is available for this method. This paper addresses this issue, by providing a comprehensive evaluation with respect to the standard planar calibration technique in the(More)
Clusters of Microcalcifications and masses are the signs of breast cancer. They have different shapes and sizes. Globally, clusters and masses have different frequency characteristics. Due to small size of microcalcifications and high intensity of them with compared to their neighbour pixels, microcalcifications correspond to high-frequency components of(More)
Musical staff detection and removal is one of the most important preprocessing steps of an Optical Music Recognition (OMR) system. This paper proposes a new method for detecting and restoring staff lines from global information of music sheets. First of all the location of staff lines is determined. Therefore, music staff is sliced. The staff line segments(More)
To solve the existing dilemma between making good range resolution and maintaining the low average transmitted power, the pulse compression technique is used. It is necessary for the pulse compression processing to give low range sidelobes. The traditional pulse compression algorithms based on 13-element Barker code such as direct autocorrelation filter(More)
