1. How do I handle lossless and lossy compression?

2. There are two parts: loseless compression and lossy compression.

3. The trend in medical image compression isincreasingly toward lossy compression.

4. Near lossless compression is a trade off between lossy compression and lossless compression.

5. Vector quantization ( VQ ) is a popular lossy compression scheme widely used in multimedia data compressions.

6. As one method of image lossy compression vector quantization has great compression ratio.

6. try its best to collect and create good sentences.

7. It has been proved by experiments that this algorithm is high imperceptibility , high capacity, and robust to affine transformation and JPEG lossy compression.

8. Experimental results show that the proposed technique has good efficiency, security, imperceptibility, highly good robustness to common image processing operation and the JPEG lossy compression.

9. However, it performs a little worse compared to the conventional Discrete Wavelet Transform ( DWT ) for lossy compression.

10. In many cases even the small changes resulting out of lossy compression systems yield to total information loss.
