【摘要】 针对植物叶片图像的特点,设计了一套将图像压缩方法和基于样本块的图像修复技术相结合的方案.先对压缩图像进行边缘提取,只保留叶脉等重要信息,丢弃冗余块实现压缩.然后对不完整的图像进行二次压缩,用于网络存储和传输,需要使用时经过图像修复处理获得完整图像.实验结果表明,该方案在保证图像质量的前提下,能有效提高图像的压缩比.更多还原

【Abstract】 For a small plant leaf features,we design a set of image compression method and sample block-based image restoration techniques combined solution.First,we compressed image edge extraction,leaving only the veins and other important information,discarding redundant blocks.Then the image is not complete secondary compression for network storage and transmission,after the image restoration processing to obtain a complete picture when needed.Experimental results show that the image quality assurance program under the premise,can effectively improve the image compression ratio.更多还原
