摘要

DNA微阵列是生物和医学研究中最先进的工具。在这项工作中，我们讨论了DNA微阵列图像有损压缩的适用性，并强调了使用失真度量来评估相关信息损失的必要性。我们还提出了一种可能的度量，该度量考虑了大多数DNA微阵列分析技术所采用的基本图像特征。实验结果表明，所提出的度量可以识别和区分DNA微阵列图像中重要和不重要的变化。

A Distortion Metric for the Lossy Compression of DNA Microarray Images

DNA micro arrays are state-of-the-art tools in biological and medical research. In this work, we discuss the suitability of lossy compression for DNA micro array images and highlight the necessity for a distortion metric to assess the loss of relevant information. We also propose one possible metric that considers the basic image features employed by most DNA micro array analysis techniques. Experimental results indicate that the proposed metric can identify and differentiate important and unimportant changes in DNA micro array images.
