Abstract:
An arrangement comprising:a compression engine configured to compress image-based rendering (IBR) data using a wavelet transform and output a compressed bitstream comprising encoded frequency coefficients associated with the IBR data, wherein the IBR data comprises a plurality of concentric mosaic images for a represented scene, and wherein the compression engine is further configured to align at least two of the plurality of concentric mosaic images to increase correlation between the at least two concentric mosaic images; a decompression engine configured to receive the compressed bitstream, selectively decode portions of the compressed bitstream based on an access request, decompress the decoded portions using an inverse wavelet transform, and output decompressed IBR data, wherein the access request is based on a desired view of at least a portion of the scene; and a rendering engine configured to provide the access request to the decompression engine, the access request, the rendering engine being further configured to render the decompressed IBR data.
