有损图像压缩 meaning in English

lossy image compression

Finally , lossless compression by means of integer lifting scheme is realized . after selecting a practical bases of lifting scheme transform , we put forward to two lossy compression algorithms based on adaptive transform and demonstrate its feasibility and validity by simulation and experiment
实现了将整数提升框架应用于无损压缩；选择了一个实际可行的提升变换基库，给出了两种基于自适应变换的有损图像压缩算法，实验仿真结果证明了算法的可行性及有效性。
