This kind of two - channels wavelets decomposition methed reconstruct the wavelet coefficients of an image from the radon transform data, and these coefficients were made reverted wavelet transform obtain the original image. wavelets subsampled on the quincunx lattice, which can have cut - off at an angle during the wavelets decomposition
基於不可分離mra的小波演算法將投影數據進行二維濾波，其二通道的小波分解直接得到小波的近似系數和細節系數，這些系數再經過逆小波變換就得到了最終的重建圖像。 -
The fuzzy division of the character lattice image can overcome the stroke position influence to the feature extraction. the fuzzy direction feature combines the fuzzy image division with the fuzzy direction property feature, which describes the stroke direction property of single edge point
通過對字元點陣圖像的模糊劃分，克服筆畫位置對特徵抽取的影響；用模糊方向屬性特徵描述單個邊緣點筆畫方向屬性；模糊方向特徵是圖像的模糊劃分和邊緣點的模糊方向屬性特徵的結合。 -

The algorithm transforms 2 - dimesion image data to 1 - dimension data by projecting the character binary image on vertical and horizon direction, as to a character image of w x h size, it reduced the operation time from about w + h level to about w x h level compared to the traditional algorithm and greatly reduced the time complexity of later processing, meanwhile it saved enough vertical and horizon lattice distribution information of the character
演算法通過將字元二值化點陣圖像進行垂直與水平方向投影，實現了從二維圖像數據到一維數據的轉化，對于w h大小字元圖像，相對于傳統演算法，本演算法將運算量從w h數量級將至w + h數量級，大大降低了后續處理運算的時間復雜度，同時保留了足夠的關于字元垂直及水平點陣分佈的特徵信息。 -
These two method are based on the characters of lattice diagram ( which characters are resembled with black - and - white image ) raise the marking route pick - up algorithm, the algorithm can found mark points in the least time by ransacking the eight points nearby. by using these two methods can improve the marking effect and accelerate the marking speed dramatically. at last, the paper give the effective evaluating method for the two route optimum algorithm, the evaluating results show that the marking speed tan improve nearly one time, and meanwhile improve the marking quality
最後，鑒于對漢字的轉化處理是在點陣漢字打標的基礎上進行的，所以通過與點陣打標相比（主要是在打標速度方面） ，提出了兩種打標路線優化演算法的效果評估方法，並對演算法效果進行試驗性測試，結果表明與點陣打標方法相比，打標速度提高的最小比率為：筆劃跟蹤演算法48 ；筆劃提取演算法37 ；可見，兩種演算法的提出可以使打標速度得到提高，說明在不改變打標系統本身，而從對漢字內容的處理上就可以達到改進打標性能的目的，所以本課題的研究的有實際的應用價值。
