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.
二值圖像編碼在文本存儲、圖象檢索中有廣泛的應用。
The "intensity moment", which is preserved in the color image, is called bi-level threshold algorithm of moment 4-D clustering.
這種稱爲矩—四維聚類的兩級閾值化算法不僅簡單實用，而且傚果較好。
An optimum threshold is selected by maximizing the correlation between the original halftone image and the thresholded bi-level image.
該算法以原始圖像與分割後圖像的相關系數最大爲準則，選取最優閾值對磨粒圖像進行二值化。
