Yacc說(shuō)明及使用文檔
yacc(Yet Another Compiler Compiler),是Unix/Linux上一個(gè)用來(lái)生成編譯器的編譯器(編譯器代碼生成器)。yacc生成的編譯器主要是用C語(yǔ)言寫(xiě)成的語(yǔ)法解析器(Parser),需要與詞法解析器Lex一起使用,再把兩部份產(chǎn)生出來(lái)的C程序一併編譯。yacc本來(lái)只在Unix系統(tǒng)上才有,但現(xiàn)時(shí)已普遍移植往Windows及其他平臺(tái)。
我用matlab寫(xiě)的一個(gè)corner detector, 效果比現(xiàn)在流行的harris,susan,CSS等效果要好。
Algorithm is derived from:
X.C. He and N.H.C. Yung, Curvature Scale Space Corner Detector with Adaptive Threshold and Dynamic Region of Support , Proceedings of the 17th International Conference on Pattern Recognition, 2:791-794, August 2004.
Improved algorithm has been included in A Corner Detector based on Global and Local Curvature Properties and submitted to Optical Engineering.
C in A Nutshell
Learning a language--any language--involves a process wherein you learn to rely less and less on instruction and more increasingly on the aspects of the language you ve mastered. Whether you re learning French, Java, or C, at some point you ll set aside the tutorial and attempt to converse on your own. It s not necessary to know every subtle facet of French in order to speak it well, especially if there s a good dictionary available. Likewise, C programmers don t need to memorize every detail of C in order to write good programs. What they need instead is a reliable, comprehensive reference that they can keep nearby. C in a Nutshell is that reference.
RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digital signature . Its security based on Integer Factorization Problem (IFP). RSA uses an asymetric key. RSA was created by Rivest, Shamir, and Adleman in 1977. Every user have a pair of key, public key and private key. Public key (e) . You may choose any number for e with these requirements, 1< e <Æ (n), where Æ (n)= (p-1) (q-1) ( p and q are first-rate), gcd (e,Æ (n))=1 (gcd= greatest common divisor). Private key (d). d=(1/e) mod(Æ (n)) Encyption (C) . C=Mª mod(n), a = e (public key), n=pq Descryption (D) . D=C° mod(n), o = d (private key
