GSAED a new aproach for digital image edge detection

In this paper, a new algorithm for image edge detection using Gravitational Search Algorithm (GSA) is proposed. In order to adapt the proposed algorithm to edge detection problem, some modification is applied on the original GSA. Each image pixel is considered as a celestial body and its mass is considered to be corresponding to the pixel´s grayscale intensity. To find out the edgy pixels a number of agents are randomly generated and initialized through the image space. Artificial agents move through the space via forces of bodies that are located in their neighborhood. A large number of experiments are employed to determine suitable algorithm parameters and confirm the legitimacy of the proposed algorithm.
