Abstract:
1. A method of removing redundant data of a simple texture model, the method comprising: calculating normal vectors of pixels projected into a three-dimensional (3D) space by using depth images among a plurality of simple texture images, the plurality of simple texture images rendering different aspects of a 3D model; calculating reliabilities of the pixels of each of the simple texture images by using the calculated normal vectors of the pixels; and comparing the reliabilities of pixels that originate from different simple texture images but render a same portion of the 3D model and removing the pixels having low reliabilities from the different simple texture images from which they respectively originate, wherein the calculation of the reliabilities of the pixels comprises considering pixels that have reliabilities that differ from each other by a predetermined critical value or less are as having a same reliability.
