character mean entropy

Average-Entropy Based Stopping Criterion for Turbo Iterative Decoding;

基于平均熵的Turbo码迭代译码停止准则

With the increasing of commercial flat mails attached with mailing labels, a way of precise character segmentation is presented by combining the way of projection with the adaptive average-character-interval in order to sort these mails automatically.

在各种贴有标签的商业扁平件日益增多的情况下,为实现这些邮件的分拣自动化,应用投影方法结合自适应平均字符间距对邮政编码进行精确的切分。
