Study shows that the basic principles of three existed methods for phase difference correction on discrete spectrum are identical, by which the twice fft analysis through time - domain shifting time series or changing window ' s length is performed, and the spectrum by making use of the phase difference of two corresponding peak lines are finally corrected
在研究時域平移的離散頻譜相位差校正方法和改變窗長離散頻譜相位差校正方法的基礎上，發現這幾種離散頻譜相位差校正法的基本原理是一致的，就是通過時移和加不同的對稱窗進行兩次fft分析，並利用離散頻譜對應峰值譜線的相位差以求得頻率和相位校正量。 -
The discrete expression of frt is studied and presented, and program is composed according to the fast algorithm, so that the digital implementation of anamorphic fc becomes possible. the connection of anamorphic fc peak and fractional orders is a problem of higher dimensional optimization. based on theoretical analysis and simulated annealing algorithm and programs we compose, the optimized orders and correlation peaks are gained while the patterns detected have dilation
求解變形分數相關峰輸出與分數階的關系是高維變量優化問題，基於理論分析的結果，採用模擬退火演算法及自編程序對相關信號產生縮放的情形進行了計算模擬，獲得了優化的分數階及相關輸出，並對信號發生移動時，相關峰的變化進行了計算模擬和分析。 -
First the object contour is translated into a 1 - d contour curve. secondly the curve is smoothed to restrain the noise. the number of peaks of the curve is achieved as well as the areas which contained between adjacent peak - valley, then the latter is followed by discrete fourier transformation ( dft )
首先將目標輪廓轉換成一維輪廓曲線，平滑去噪，然後獲得曲線峰數和輪廓曲線在相鄰峰谷間所含面積，並對後者進行dft變換，提取出具有平移、旋轉、尺度不變性的兩類特徵。
