Wavelet-transform-based stereo residual image compression
Jung-Jin Kim, Ji-Sang Yoo, Eun-Soo Kim · Optical Engineering · 2002
A new stereo image compression algorithm is described in which the residual image, extracted from the stereo image by the disparity-compensated prediction method, is compressed using the wavelet transform in consideration of the inter and intra correlation between subbands. Contrasting the conventional algorithms such as efficient pyramid image code (EPIC), embedded predictive wavelet image coder (EPWIC), and JPEG, compression performance of the suggested method is significantly improved through computer simulation. Finally, it is suggested that the stereo image having a good 3-D effect can be reconstructed from the compressed image data using a new algorithm described.
