| 摘 要： | 岩心图像数据量很大,不便存储和传输,需要进行压缩。岩心图像编辑器采用标准的JPEG压缩方法,需要对编辑器进行设计。编辑器结构分为编码过程和解码过程,其功能包括FDCT(正向离散余弦变换)和IDCT(DCT逆变换)、量化和反量化、DC编解码和AC系数排序、熵编码和熵解码。可实现岩心图像的无损压缩。

| Abstract: | Data volume of core image was big,not appropriate for storage and transfer,it needed to be compressed.Standard JPEG compression method was used in core image editor,thus it needed to be designed.The editor structures include encoding and decoding.Its function include FDCT,IDCT,quantification and anti-quantification,DC encoding and AC coefficient ordering,entropy encoding and decoding.It can be used for lossless core data compression. |
