Chapter 4 designs and determines the parameters of the algorithm adopted in the instrument system. analyzes and compares the different effects to frequency estimation when using digital filters with different group delay ; determines the data length, a parameter of frequency estimation ; introduces the method of available judgment of sensing signal and determines the judgment threshold as well
第四章設計和確定了儀器系統軟體演算法的部分參數：分析和比較了不同群延遲特性的數字濾波器對頻率估計的影響；確定了影響頻率估計參數?數據長度的取值規律；給出了判斷傳感信號有效性的檢測方法並確定了檢測門限的取值規律。 -
Moving object detection adopts a method of dynamic difference background image, whose principle is to calculate difference picture among the current frames and background images and take the motion adjudging threshold which owns maximum information entropy to determine moving area ; and dynamically updates background by using kalman filter. thus, the system realizes the judgment of the moving area under the complicated changing background
運動目標檢測採用動態差分背景圖像法，其原理是利用序列圖像中當前幀圖像減去背景圖像，並採用使信息熵最大化的運動判決門限判定運動區域;採用kalman濾波動態背景生成實現了背景的動態更新;從而實現了復雜變化背景下圖像運動區域的判決。 -
Nowadays, the popular image segmentation methods almost take part in the time space of the image, but in this paper, the processed images are transformed form time space to frequency space. thus avoid dealing with isolated pixels in the image, and use correlated phase function as the judgment rule to search for the optimal threshold value from the global solution space
目前，大多數圖像分割方法都是在時域進行的;本文將圖像從時域變換到頻域，避免了對圖像中每一個像素進行單獨處理，使用了相位相關性函數作為評價函數，全局搜索最優解。
