基于图像绘制场景的压缩方法

Compressing Method of Image-based Rendering Scene

基于图像绘制场景的压缩方法先采用光场方法、同心拼图完成真实场景数据的采集。再用块编码、参考编码和高维变换(小波)编码等三类IBR压缩系统对照片集图像数据进行压缩。块编码压缩光场和同心拼图中的区域块,用空间矢量量化重新编码。参考帧编码经RBC压缩比特流加快实时绘制。用高维小波变换压缩同心拼图达到最佳的压缩率。

The compression method of image-based rendering （IBR） is that light-fields and concentric mosaics means were used to complete data acquisition of actual scene. The image data of the photo set was compressed with IBR compression algorithms such as the block coder, the reference coder and multidimensional wavelet transform. Area block in light-fields and concentric mosaics was compressed with block coder, and it was recoded with space vector quantization. The reference coder can be mended real time rendering through RBC compression ratio. concentric mosaics was compressed with multidimensional wavelet transform to achieves the best compression ratio.
