Abstract
A method for determining an estimated clutter level of an input digital image based on an inequality index. The inequality index is determined by analyzing the input digital image to determine a set of image features. The image features are associated with a set of designated reference features, and the inequality index is determined based on the statistical variation of the reference features. A set of scene content features relating to spatial structures or semantic content of the input digital image is determined by analyzing the input digital image. The estimated clutter is determined responsive to the inequality index and the scene content features.
Claims14
A method for determining an estimated clutter level of an input digital image, the method being performed at least in part using a data processor, comprising:
- designating a set of reference features;
- determining a set of image features by automatically analyzing the input digital image;
- associating each of the determined image features with the reference features;
- forming a frequency distribution representing a frequency of occurrence of the associated reference features for the input digital image;
- analyzing the frequency distribution to determine an inequality index, the inequality index being a measure of statistical variation of the reference features;
- analyzing the input digital image to determine scene content features relating to spatial structures in the input digital image or semantic content of the input digital image;
- and
- determining the estimated clutter responsive to the inequality index and the scene content features.
