ABSTRACT:
The image processing system has a unit for photographing an object in two dimensions, a feature extraction unit for extracting features from the two-dimensional image data from the photographing means, and a three-dimensional shape reproduction unit. The feature extraction unit refers to feature points given to the object to extract the features. The three-dimensional shape reproduction unit expresses the object by a dynamic equation, applies force from the feature extraction coordinates to the dynamic model to cause the dynamic model to change shape and supplement depth data, and to thereby reproduce the three-dimensional shape of the object. To increase the speed of the processing, it is desirable to divide the image data of the object into portions with little changes in shape and perform the processing for reproducing the three-dimensional shape for each mode.
