A method for detecting a main subject in an image comprises the steps of: (i) computing a plurality of saliency features from the image (14) with a control system (20); (ii) generating a spatial weight map for each of a plurality of image segments of the image (14) with the control system (20); (iii) adjusting the plurality of saliency features via the spatial weight map to generate a plurality of adjusted saliency features; (iv) combining at least two of the plurality of adjusted saliency features to generate a saliency map of the image (14); and (v) extracting the main subject from the saliency map of the image (14). Additionally, the plurality of saliency features can include at least two of a sharp/blur saliency feature, a spectral residual saliency feature, a color spatial distribution saliency feature, and one or more color contrast saliency features. |
