Block check character
字塊檢驗字元With this method, the compressed bit - streams, which are encoded by dct - based encoding algorithm, can be processed directly to locate the character - regions in the images, just a very small amount of decoding is required so, the amount of data which want to process is smaller, the processing speed is faster and the demand of computer memory is less
文獻中將此模型用在以dct為編碼基礎壓縮數據上,效果較好。本文將其演算法中的能量定義利用塊間的信息重新定義,並且採用自適應動態閾值對原演算法進行改進。對比實驗結果表明,改進的方法對圖像字元定位比原方法準確率更高,漏檢情況有一定程度的降低,取得了較好的效果。
