最後，在傳統的邊緣檢測演算法和小波分析的邊緣檢測演算法之外，對以下幾個方面也進行了一些討論： 1 ）利用誤差圖像來提高邊緣檢測效果的演算法； 2 ）將求解任意方向的一階、二階方向導數的問題轉換到頻域中去求解，發現在頻域中它們具有簡單易用的公式，使得原來求解任意方向的一階、二階導數的比較困難的問題變得容易實現了。 -
Second, the results of theory analysis and simulation research show that the output of one cycle controlled bridge switching power amplifier have dc offset because of the nonideal characteristic of reset signal. the magnitude of output dc offset voltage is proportional to width of reset pulse. a voltage compensation technique is used to solve this question, and the computation formula of compensation voltage is gived. the circuit compensated and not are researched through simulation and experiment, which results show that compensated circuit solve the output dc offset effectively
