基于"trace transform"的識別2D圖像的C++源程序, 主文件是tt.cpp, 在LINUX下可以用 g++ tt.cpp -o tt -O3進行編繹, 而且最后的結果也可以在MATLAB下顯示出來, This package presents C++ tools to the trace transform of a 2D image, and related objects, i.e. circuses and triple features, matlab tools to visualise these entities, and tools to check newly coded functionals. This version is released with a small number of functionals only.

考察例1 4 - 8中的1 4個點。A中的最近點對為(b,h),其距離約為0 . 3 1 6。B中最近點對為 (f, j),其距離為0 . 3,因此= 0 . 3。當考察 是否存在第三類點時,除d, g, i, l, m 以外 的點均被淘汰,因為它們距分割線x= 1的 距離≥ 。RA ={d, i, m},RB= {g, l},由 于d 和m 的比較區中沒有點,只需考察i 即可。i 的比較區中僅含點l。計算i 和l 的距離,發現它小于,因此(i, l) 是最近

利用函數MadHG生成規則LDPC碼的校驗矩陣H,其行重為6,列重為3,行數為列數一半(行數越大越好),H中任意兩列沒有圍長為4的圈,并得到H對應的生成矩陣G,可以保證mod(G*H ,2)=0。使用方法為:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分為單位陣) or 2(G右半部分為單位陣),

penMesh is a generic and efficient data structure for representing and manipulating polygonal meshes. OpenMesh is developed at the Computer Graphics Group, RWTH Aachen , as part of the OpenSGPlus project, is funded by the German Ministry for Research and Education ( BMBF), and will serve as geometry kernel upon which the so-called high level primitives (e.g. subdivision surfaces or progressive meshes) of OpenSGPlus are built. It was designed with the following goals in mind : Flexibility : provide a basis for many different algorithms without the need for adaptation. Efficiency : maximize time efficiency while keeping memory usage as low as possible. Ease of use : wrap complex internal structure in an easy-to-use interface.

crc任意位生成多項式 任意位運算 自適應算法 循環冗余校驗碼(CRC,Cyclic Redundancy Code)是采用多項式的 編碼方式,這種方法把要發送的數據看成是一個多項式的系數 ,數據為bn-1bn-2…b1b0 (其中為0或1),則其對應的多項式為: bn-1Xn-1+bn-2Xn-2+…+b1X+b0 例如:數據“10010101”可以寫為多項式 X7+X4+X2+1。 循環冗余校驗CRC 循環冗余校驗方法的原理如下: (1) 設要發送的數據對應的多項式為P(x)。 (2) 發送方和接收方約定一個生成多項式G(x),設該生成多項式 的最高次冪為r。 (3) 在數據塊的末尾添加r個0,則其相對應的多項式為M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x),獲得商Q(x)和余式R(x),則 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x),采用模2運算,T(x)所對應的數據是在原數 據塊的末尾加上余式所對應的數據得到的。 (6) 發送T(x)所對應的數據。 (7) 設接收端接收到的數據對應的多項式為T’(x),將T’(x)除以G(x) ,若余式為0,則認為沒有錯誤,否則認為有錯

RTX-51 is a runtime library that, together with C51, allows real-time systems to be implemented for all processors of the 8051 family (e.g., 8051, 8052, 80515, etc.), except for the 8?C751 and 8?C752. RTX-251 extends the functionality of the RTX-51 to the new intel MCSÒ 251 family of processors. It is available as a set of runtime libraries supporting the binary and the source mode to be used with the C251.
