This dissertation proposes an algorithm to detect edges and extract contours from medical images based on quadric spline wavelets transform . the algorithm can generate single , continuous and close contours . there are two main methods of surface reconstruction ? explicit connecting contours method and implicit function method 利用小波變換良好的局部化特性和其固有的多尺度特性,具體針對醫學圖象邊緣輪廓提取的特點,提出一種基于二次樣條小波變換的邊緣檢測和輪廓提取方法,提取出單像素和連續封閉的邊緣輪廓。

Paper [ 76 ] provides a integer algorithm for rasterizing free curves , we need change the curve form to implicit function form , then use curve ' s positive - negative property to draw , but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm , this algorithm can draw bezier very well , but for b - spline curve , we need use convert them into bernstein base form . because this process spends a lot of time , this algorithm has not a good speed and effect for rendering rational b - spline curve 現在經常采用的算法也是基于幾何的算法(即線式生成算法)和基于像素的算法(點式生成算法) ;文獻78 ]提供了一種有理參數曲線的快速逐點生成算法,該算法對有理b吮ier曲線的繪制,能起到很好的作用,但是對于有理b樣條曲線,必須先通過多項式的代數基與bemstein基間的變換矩陣,把原式用bemstein基表示,這一過程由于計算量大,降低了曲線生成的速度和效率

25 shapiro v , tsukanov i . implicit functions with guaranteed differential properties . in symposium on solid modeling and applications , ann arbor , michigan , usa , 1999 , pp . 258 - 269 特別是,這些變形計算是可層次化進行的,使得csg樹中的所有從根到葉子的結點都能進行變形。

A more subtle cause of side effects is the evaluation of properties and other implicit function calls in managed code 產生副作用的一個更難以捉摸的原因,是在托管代碼中計算屬性和其他隱式函數調用。

Turns on automatic evaluation of properties and implicit function calls in variables windows and quickwatch dialog box 在變量窗口和“快速監視”對話框中打開屬性的自動求值和隱式函數調用。

Implicit function arguments , loose syntax , and liberal program structures add to perl s charm 隱含的函數聲明、不嚴格的語法、以及象日用文檔似的程序結構使得perl更具吸引力。

This can be useful when implicit evaluation of properties and implicit function calls is turned off 當關閉屬性的隱式計算和隱式函數調用時,這是很有用的。

The debugger cannot tell whether a property evaluation or implicit function call has side effects 調試器無法區分是屬性計算還是隱式函數調用產生副作用。

When evaluation of properties or implicit function calls is turned off , you can force evaluation by using the 當關閉屬性計算或隱式函數調用時,可以使用

Therefore , by default , the debugger does not evaluate implicit function calls automatically 因此,默認情況下,調試器不會自動計算隱式函數調用。
