Abstract:
1. A method for generating an enhanced image, the method comprising the steps of: (a) receiving a matrix of pixels representative of an image; (b) generating a gradient image, the gradient image comprises a matrix of values, representative of a difference between values of adjacent pixels; (c) calculating a center of mass for each pixel of the gradient image in response to gradient intensity values and location values of neighboring pixels; and (d) generating an enhanced image by modifying intensity values of pixels of the matrix of pixels that are located in a vicinity of local centers of mass in response to intensity values of pixels that are further displaced from the local center of mass; wherein neighboring pixels of each pixel of the gradient image comprise pixels within a neighborhood pattern and a pixel is located in the vincinity of local center of mass if a distance between the pixel and at least a portion of the local center of mass does not exceed a length of the neighborhood pattern.
