An image processing device which simultaneously secures and extracts a background image, at least two object images, a shape of each object image and motion of each object image as hidden parameters, from among plural images, the image processing device including an image input unit (101) which accepts a time series of images; a hidden parameter estimation unit (102) which estimates a hidden parameter based on the plural images and a constraint enforcement parameter, which indicates a condition of at least one of the hidden parameters, using an iterative learning method; a constraint enforcement parameter learning unit (103) which learns a constraint enforcement parameter related to the hidden parameter using an estimation result from the hidden parameter estimation unit as a training signal; and a complementary learning unit (104) which causes the estimation of the hidden parameter and the learning of the constraint enforcement parameter, which utilize the result from the learning of the hidden parameter, to be iterated. The object images are superimposed on the background image and an error measure can trigger repetition of the estimation with an increased number of frames. |
