Abstract
A system and a method are disclosed for generating a saliency map of an image. The method includes receiving image data representative of image forming elements of an image and determining saliency values for image forming elements by an iterative method. The iterative method includes computing a norm of the image data, computing values of deviation from the norm of the image data of the image forming elements, identifying the image forming elements corresponding to the image data having magnitudes of deviation that meet a pre-determined condition, assigning saliency values to the identified image forming elements based on the values of deviation, and repeating the computing the norm and deviation, identifying image forming elements and assigning saliency values using the image data of image forming elements that have no assigned saliency value. A saliency map of the image based on the assigned saliency values.
