bi-level image

基本解释

Bi-level image coding is useful for document storage and archiving, image searches on the Internet and digital libraries.
二值图像编码在文本存储、图象检索中有广泛的应用。
The "intensity moment", which is preserved in the color image, is called bi-level threshold algorithm of moment 4-D clustering.
这种称为矩—四维聚类的两级阈值化算法不仅简单实用，而且效果较好。
An optimum threshold is selected by maximizing the correlation between the original halftone image and the thresholded bi-level image.
该算法以原始图像与分割后图像的相关系数最大为准则，选取最优阈值对磨粒图像进行二值化。
