中文摘要:
      目的 研究结合人眼感知特性的彩色图像压缩技术。 方法 结合人眼对比度敏感视觉特性及其数学模型, 基于彩色图像频谱特征, 提出一种适合于彩色图像的压缩算法方案, 并对图像进行3 种压缩比的压缩仿真实验。 结果 提出的压缩算法方案在完全不影响人眼观察的情况下压缩比可达15∶1,压缩比达到 64.1538∶1 时, 解压缩图像仍能在一定的误差范围内达到较好的视觉效果, 且PSNR仍能达到 30 dB 以上。 结论 提出的压缩算法方案在保证图像压缩质量的前提下能够实现较高的压缩比, 完全可以满足实际生活中彩色图像存储和传输的需要。
英文摘要:
      Objective To study the color image compression technology based on human perception characteristics. Methods Combined with human visual characteristics and its mathematic model, based on the color image frequency spectrum characteristics, an image compression scheme was proposed to be suitable for color image, and the simulation experiments were carried out with three different compression ratios. Results In the color image compression scheme proposed, the compression ratio could reach 15∶1 under the conditions of not affecting the human observation by comparison and analysis. When the compression ratio reached 64.1538∶ 1, the decompressed image could still achieve a relatively good visual effect in a certain range of error, and the PSNR could reach more than 30 dB. Conclusion Experiment results showed that the proposed compression algorithm scheme could achieve relatively high compression ratios under the premise of image compression quality, which could completely meet the requirement of color image storage and transmission in real life.
