to solve the problem of huge storage occupation for usps handwritten numerals sample library, a method for accessing handwritten character sample image information based on bit map coding is presented in the pager 摘要針對usps手寫數(shù)字樣本數(shù)據(jù)庫存儲空間大,在開發(fā)實際手寫數(shù)字字符識別系統(tǒng)時不能直接生成二值化圖像的缺點,提出一種基于位映象編碼的二進制存取方法,建立的手寫樣本數(shù)據(jù)庫可以快速恢復(fù)為相應(yīng)的二值化字符圖像。
