3-D image coding based on affine transform

DOI

Description

This paper is concerned with the data compression and interpolation of multi-view images. We propose the affine-based disparity compensation based on a geometric relationship. We first investigate the geometric relationship between the point in object space and its projection onto a view image. Then, we propose the disparity compensation based on the affine transform, which utilize the geometric constraints between view images. In this scheme, multi-view images are compressed into the structure and texture of the triangular patches. This scheme not only compresses the multi-view image but also synthesize the view images from any viewpoints in the viewing zone, because the geometric relationship is taken into account. Finally, we report an experiment, where 19 view images were used as the original multi-view image and the amount of data was reduced to 1/19 with an SNR of 34 dB. >
