Claim One:
1. A foreground action estimating apparatus for estimating foreground actions in a picture comprising: a training image inputting means for inputting a foreground image, a background image and an image having the foreground and background images as training images; a basis matrix calculating means for calculating a foreground basis matrix and a background basis matrix by respectively extracting a foreground feature and a background feature from the foreground image and the background image, respectively, and combining the foreground basis matrix and the background basis matrix to obtain a combined basis matrix; a feature suppressing means for calculating feature coefficients of the training images in accordance with the combined basis matrix obtained by the basis matrix calculating means to obtain background-feature-suppressed image features of the training images; and a foreground action information acquiring means for estimating foreground action information in accordance with a feature mapping matrix from the image features to an action information set, by using the background-feature-suppressed image features.
