shc是一個加密shell腳本的工具.它的作用是把shell腳本轉(zhuǎn)換為一個可執(zhí)行的二進(jìn)制文件.
用shell腳本對系統(tǒng)進(jìn)行自動化維護(hù),簡單,便捷而且可移植性好.
但shell腳本是可讀寫的,很有可能會泄露敏感信息,如用戶名,密碼,路徑,IP等.
同樣,在shell腳本運行時會也泄露敏感信息.
shc是一個加密shell腳本的工具.它的作用是把shell腳本轉(zhuǎn)換為一個可執(zhí)行的二進(jìn)制文件.
這就很好的解決了上述問題.
tar zxvf shc-3.8.tgz
cd shc-3.8
make test
make
make test
make strings
make install 這一步需要root權(quán)限
使用方法:
shc -r -f script-name 注意:要有-r選項, -f 后跟要加密的腳本名.
運行后會生成兩個文件,script-name.x 和 script-name.x.c
script-name.x是加密后的可執(zhí)行的二進(jìn)制文件.
./script-name 即可運行.
script-name.x.c是生成script-name.x的原文件(c語言)

中心點漂移是一種非監(jiān)督聚類算法（與k-means算法相似，但應(yīng)用范圍更廣些),可用于圖像分割，基于Matlab實現(xiàn)的源碼。
MedoidShift is a unsupervised clustering algorithm(similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.
k-meansy算法源代碼。This directory contains code implementing the K-means algorithm. Source code
may be found in KMEANS.CPP. Sample data isfound in KM2.DAT. The KMEANS
program accepts input consisting of vectors and calculates the given
number of cluster centers using the K-means algorithm. Output is
directed to the screen.
