Several techniques for performing digital image restoration are reviewed and the problems associated with evaluating image processing are discussed. An application of constrained deconvulution to images of the liver produced by single-photon emission computed tomography is presented. Specific evaluation criteria are suggested and based on these, the choice of conditions best suited for processing liver images is proposed. Typically cold tumor contrast can be improved by a factor of greater than 2 whilst image mottle increases negligibly.
回顾了几种用于数字图像恢复的技术,并讨论了与图像处理评估相关的问题。介绍了约束反卷积在单光子发射计算机断层扫描产生的肝脏图像中的应用。提出了具体的评估标准,并在此基础上提出了最适合处理肝脏图像的条件选择。通常,冷肿瘤对比度可以提高2倍以上,而图像斑点增加可忽略不计。
