METHOD AND PROGRAM FOR EXTRACTING SILHOUETTE IMAGE AND METHOD AND PROGRAM FOR CONSTRUCTING THREE DIMENSIONAL MODEL

摘要

A present invention provides a method and a program for extracting the high accuracy silhouette by relatively simple process not using manual labor or special photography environment. A method for extracting the high accuracy silhouette comprises: extracting a number of first silhouettes from a number of object images and a number of background images by a background subtraction; constructing first visual hull from a number of the first silhouettes by a shape from silhouette method; constructing second visual hull by process to repair missed parts and/or to remove unwanted regions in first visual hull; and extracting a number of second silhouettes from the second visual hull.
