To the complete character use the image which representation by matrix, making the subtraction between the matrix of capture image and the matrix of template, the result matrix which absolute sum of its all elements is the smallest is the recognition result. to the incomplete character, using two lines of 0 ~ 9 as template, then carry on the recognition using the template matching. to the scale division recognition, using the central position of it, distinguishes the long scale division expression is merely 0 perhaps 5
對完整字元，採用將圖像用矩陣表示，利用獲取圖像的矩陣與識別模板的矩陣做減法，結果矩陣的所有元素絕對值和最小的即為識別結果;對不完整字元，針對電度表讀數的具體特點，採用將兩行0 ~ 9的字元圖像排列起來作為模板，利用模板匹配法進行識別;對于刻度的識別，利用刻度的中心坐標位置，僅僅識別長刻度表示的是0或是5即可。 -
A decoding algorithm based on transform and fast hadamard transform changes the matrix multiplication to the addition, subtraction and position exchanging among the matrix elements, so reduces the demand of the instrument for computer
基於變換和快速阿達瑪變換的解碼演算法，將矩陣乘法簡化為矩陣元素間的加、減運算和位置交換，降低了儀器對微機系統的要求。
